VOS3000 Position Keeper Dollar Sign: Best Strategic Dial Plan Variable Retention

April 28, 2026April 28, 2026 king

VOS3000 Position Keeper Dollar Sign: Strategic Dial Plan Variable Retention

📞 When transforming phone numbers in VOS3000 dial plans, there are times when you need to insert or change a prefix while preserving the exact digits that follow at their original positions. This is where the VOS3000 position keeper dollar sign ($) becomes indispensable. The dollar sign in a Target Prefix tells VOS3000 to keep and not change the digit at that position from the original number — essentially “passing through” the matched digit unchanged while allowing other transformations around it. 🔧

⚙️ The VOS3000 2.1.9.07 manual §4.3.1 provides the definitive example: Original Prefix “0134”, Target Prefix “$$$”, input number “0134131” becomes “013131”. The three dollar signs in the target prefix retain the last three digits (“131”) from the original number while the prefix “0134” is replaced. This behavior — preserving positional digits during transformation — makes the VOS3000 position keeper dollar sign one of the most powerful tools for building precise number manipulation rules. 📊

🎯 This guide covers every aspect of the VOS3000 position keeper dollar sign: how it preserves digit positions, practical transformation examples from the manual, how it interacts with wildcards and other dial plan features, and real-world scenarios where positional retention is essential.

🔐 What Is the VOS3000 Position Keeper Dollar Sign?

⏱️ The VOS3000 position keeper dollar sign ($) is a special character used in the Target Prefix field of dial plan rules. When VOS3000 encounters a dollar sign in the target prefix, it retains the digit at the corresponding position from the original dialed number without any modification. The manual §4.3.1 states it clearly: “$ means keep and not change dial plan the position.” 📞

💡 Why positional retention matters: Consider a scenario where you need to remove an area code prefix while preserving the subscriber number that follows. Without the position keeper, you would need to know the exact digits of every possible subscriber number — an impossibility in a production VoIP environment. The dollar sign lets you say “keep whatever digit is at this position” without knowing the actual digit value, enabling generic transformation rules that work across thousands of different numbers.

📋 Dollar Sign vs Asterisk Wildcard — Key Difference

🌐 Understanding the difference between the dollar sign ($) and the asterisk (*) is essential for correct dial plan configuration:

Feature	Dollar Sign ($)	Asterisk (*)
Used in	Target Prefix only	Both Original and Target Prefix
Behavior	Keeps one specific digit position unchanged	Carries forward all digits matched by * in original
Granularity	Per-digit — each $ preserves one position	Per-group — * preserves entire matched digit sequence
Position control	Exact position — $ at position 3 keeps digit at position 3	Relative — * appends all matched digits after the target prefix
Best for	Removing prefix while keeping known-length remainder	Adding prefix while keeping all remaining digits

🔑 Key distinction: The asterisk carries forward all digits as a group at the end of the target prefix, while the dollar sign preserves digits at specific individual positions. The dollar sign gives you positional precision — you can skip certain positions and keep others — while the asterisk is a bulk operation that preserves everything matched.

⚙️ How the Dollar Sign Position Keeper Works

🔧 The VOS3000 manual §4.3.1 provides the clearest example of the VOS3000 position keeper dollar sign in action:

Original Prefix	Target Prefix	Input Number	Result	Explanation
0134	$$$	0134131	013131	$ means keep and not change dial plan the position

💡 Breaking down the example: The input number is “0134131”. The Original Prefix “0134” matches the first four digits. The remaining digits after the prefix are “131” (three digits). The Target Prefix “$$$” contains three dollar signs, which means “keep the next three digits from the remaining portion unchanged.” The result “013131” can be understood as: “013” (first three digits of original) + “1” (first kept digit) + “3” (second kept digit) + “1” (third kept digit). The dollar signs preserve the positional digits from the portion after the matched original prefix.

📋 Understanding Position Mapping

Step	Description	Value
1. Match Original Prefix	“0134” matches first four digits of “0134131”	0134 → matched
2. Identify remaining digits	Digits after the matched prefix: “131”	131
3. Apply $ position keepers	Each $ preserves one digit position from the remaining portion	$=1, $=3, $=1
4. Construct result	Original prefix portion kept as-is + position-kept digits	013 + 131 = 013131

🔑 Important note: The exact behavior of how the original prefix digits are handled in the result depends on whether the Target Prefix contains only dollar signs or a combination of fixed digits and dollar signs. When the Target Prefix is “$$$” only, the result reconstructs using the positional mapping described above. The VOS3000 manual §4.3.1 confirms the example: “0134” → “$$$” transforms “0134131” to “013131”.

📊 Practical VOS3000 Position Keeper Examples

🎯 The VOS3000 position keeper dollar sign is most useful in scenarios where you need to strip or modify a prefix while preserving a known number of subsequent digits. Here are practical examples:

Scenario	Original Prefix	Target Prefix	Input	Output
Strip 4-digit area code, keep 7-digit subscriber	0134	$$$$$$$	01341234567	0131234567
Strip prefix and add new prefix with position keeping	0134	025$$$$$$	01341234567	0251234567

💡 Combining $ with fixed digits: The Target Prefix can mix dollar signs with literal digits. For example, Target Prefix “025$$$$$$” means: output the literal digits “025” followed by six position-kept digits from the remaining portion of the original number. This lets you remove one area code prefix and replace it with another while preserving the subscriber number — one of the most common VOS3000 position keeper dollar sign use cases in carrier interconnect scenarios.

🛡️ Common VOS3000 Position Keeper Problems and Solutions

❌ Problem 1: Wrong Number of Dollar Signs — Digits Truncated or Extra

🔍 Symptom: The transformed number has missing or extra digits compared to the expected result.

💡 Cause: The number of dollar signs in the Target Prefix does not match the number of remaining digits after the Original Prefix match.

✅ Solutions:

🔧 Count the remaining digits after the Original Prefix and use exactly that many dollar signs
📊 Test with representative numbers from your traffic to verify digit count
📞 Consider using the asterisk (*) instead if the remaining digit count varies

❌ Problem 2: Dollar Sign Not Preserving Digits — Literal $ Appearing in Output

🔍 Symptom: The transformed number contains literal dollar sign characters instead of preserved digits.

💡 Cause: The dial plan rule may not be matching the intended Original Prefix, causing the $ characters to be treated as literal text rather than position keeper operators.

✅ Solutions:

🔧 Verify the Original Prefix correctly matches the input number format
📊 Ensure the input number starts with the exact digits specified in Original Prefix
📞 Check for conflicting dial plan rules with higher priority in the call routing configuration

💡 VOS3000 Position Keeper Best Practices

Best Practice	Recommendation	Reason
📊 Count digits precisely	Use exactly the right number of $ signs for remaining digits	✅ Prevents truncation or padding errors
🔧 Use * for variable-length	Switch to * when remaining digit count varies	🎯 $ requires exact digit count knowledge
🔄 Combine $ with fixed digits	Prepend new prefix before $ signs when replacing area codes	🛡️ Enables prefix swap + digit preservation
📋 Test edge cases	Verify with shortest and longest expected numbers	📞 Ensures $ works across all number formats
📈 Document $ usage	Add memo comments explaining $ position mapping	🔧 Future maintainability

💡 Pro tip: The VOS3000 position keeper dollar sign is most effective when combined with callee rewrite rules and the rate prefix settings. For number formatting standards, see ITU-T E.164. Use dial plan $ rules for routing-level number transformation, callee rewrite rules for account-level adjustments, and rate prefixes to ensure the billing engine sees the correct number format.

❓ Frequently Asked Questions

❓ What is the VOS3000 position keeper dollar sign?

⏱️ The VOS3000 position keeper dollar sign ($) is a special character used in the Target Prefix field of dial plan rules. It tells VOS3000 to preserve the digit at the corresponding position from the original number without modification. According to the VOS3000 manual §4.3.1, “$ means keep and not change dial plan the position.” Each dollar sign preserves exactly one digit position, enabling precise number transformation where you remove or modify a prefix while keeping the subsequent digits intact at their exact positions.

❓ How is the dollar sign different from the asterisk in VOS3000 dial plans?

🔧 The dollar sign ($) preserves individual digit positions one at a time, while the asterisk (*) carries forward all matched digits as a group. With “$$$”, you preserve exactly three specific digit positions. With “*”, you preserve all remaining digits after the target prefix in a single operation. The dollar sign gives you positional precision — you can choose which positions to keep — while the asterisk is a bulk preservation of everything matched. Use $ when you know the exact number of digits to preserve, and * when the remaining digit count varies.

❓ Can I combine dollar signs with fixed digits in the Target Prefix?

|carrier interconnect number formatting per ITU-T E.164 standards

❓ What happens if I use too many or too few dollar signs?

📋 If you use more dollar signs than there are remaining digits after the Original Prefix match, the extra dollar signs may produce unexpected results or be treated as having no corresponding digit to preserve. If you use fewer dollar signs, only the first N digits will be preserved and the rest truncated. Always count the exact number of digits that follow the Original Prefix in your input numbers and use exactly that many dollar signs. For variable-length numbers, consider using the asterisk (*) wildcard instead of the dollar sign.

❓ Does the dollar sign work in the Original Prefix field?

🔄 No, the dollar sign position keeper is designed for use in the Target Prefix field only. In the Original Prefix, use exact digits, the asterisk (*) wildcard, or the question mark (?) wildcard for pattern matching. The dollar sign’s purpose is specifically to preserve digit positions during the transformation output — it does not have a matching function in the input pattern. The VOS3000 manual §4.3.1 only documents the $ symbol’s behavior in the Target Prefix context.

❓ How does the position keeper interact with other dial plan features?

📊 The VOS3000 position keeper dollar sign works alongside other dial plan features including wildcards (* and ?), escape characters (L/E/G/F), and semicolons. However, mixing $ with ? in the same Target Prefix requires careful attention — the ? generates a random digit while $ preserves an existing digit. Similarly, using $ within semicolon-separated targets means each target option can independently use dollar signs for positional retention. Always test combined configurations thoroughly to verify the expected transformation behavior.

VOS3000 No-CDR Free Numbers Smart Zero-Record Configuration

April 19, 2026April 19, 2026 king

VOS3000 No-CDR Free Numbers Smart Zero-Record Configuration

Configuring VOS3000 no-CDR free numbers is a powerful optimization technique for VoIP operators who handle large volumes of free calls. The SERVER_BILLING_NO_CDR_E164S parameter goes beyond simple zero-charge billing — it eliminates CDR generation entirely for matching numbers, significantly reducing database write operations and storage requirements. Need expert guidance? Contact us on WhatsApp: +8801911119966.

Unlike the FREE_E164S parameter that still produces a zero-charge CDR record, NO_CDR_E164S ensures that calls to specified numbers leave no billing trace at all. This distinction is critical for high-volume environments where thousands of free calls per hour can unnecessarily bloat the CDR database and degrade system performance.

VOS3000 No-CDR Free Numbers Parameter Details

The SERVER_BILLING_NO_CDR_E164S parameter is defined in the VOS3000 server billing configuration, as documented in section §4.3.5.1 of the administration manual. It accepts a comma-separated list of E164 number patterns, using the same wildcard syntax as other billing parameters. When a call destination matches any pattern in this list, the billing engine skips CDR creation entirely.

📋 Property	📋 Value
Parameter Name	SERVER_BILLING_NO_CDR_E164S
Configuration File	mbx2008.conf or server billing config
Data Type	Comma-separated E164 patterns
Default Value	Empty (no numbers exempt from CDR)
Wildcard Support	Yes (asterisk * for prefix matching)
Manual Section	§4.3.5.1

NO_CDR_E164S vs FREE_E164S: Critical Differences

Understanding the distinction between these two VOS3000 billing parameters is fundamental. Both handle free calls, but their impact on the billing pipeline and database is completely different. This comparison is essential for any operator implementing VOS3000 no-CDR free numbers properly.

📋 Feature	📋 FREE_E164S	📋 NO_CDR_E164S
CDR Generated	Yes (zero-charge record)	No (no record at all)
Billing Amount	0.00	N/A (no record exists)
Database Write	Yes	No
Call Tracking	Full tracking available	No tracking from CDR
Rate Table Lookup	Skipped	Skipped
Audit Trail	Preserved	None
Performance Impact	Moderate (still writes CDR)	Minimal (skips write)

When to Use VOS3000 No-CDR Free Numbers

Choosing between FREE_E164S and NO_CDR_E164S depends on your business requirements for call tracking versus system performance. Our VOS3000 specialists can help you make the right choice — reach us on WhatsApp: +8801911119966. Here are the scenarios where skipping CDR generation makes the most sense.

📋 Scenario	📋 Recommended Parameter	📋 Reason
Emergency numbers (911, 112)	FREE_E164S	Audit trail required by regulation
High-volume test numbers	NO_CDR_E164S	No need for test call records
Internal PBX extensions	NO_CDR_E164S	On-net calls need no billing trace
Toll-free customer hotlines	FREE_E164S	Track call volume for capacity planning
Health-check probe numbers	NO_CDR_E164S	Frequent automated checks, no value in CDR
Regulatory-mandated free calls	FREE_E164S	Compliance requires call records

Configuration Steps for Zero-Record Setup

Setting up VOS3000 no-CDR free numbers follows the same configuration pattern as other billing parameters. Always create a backup before modifying your server configuration — our backup and restore guide walks you through the process.

📋 Step	📋 Action	📋 Command or Detail
1	Backup configuration	cp mbx2008.conf mbx2008.conf.bak
2	Edit configuration file	vi /etc/vos3000/mbx2008.conf
3	Add NO_CDR_E164S parameter	SERVER_BILLING_NO_CDR_E164S=5000,6000,7000
4	Save configuration	:wq in vi
5	Restart VOS3000 service	service vos3000 restart
6	Verify CDR absence	Test call then check CDR table — no record should exist

Database Performance Impact Analysis

The primary advantage of VOS3000 no-CDR free numbers is the reduction in database write operations. In high-volume VoIP environments where thousands of free calls occur hourly, eliminating unnecessary CDR inserts can dramatically improve MySQL performance. For more on monitoring your VOS3000 system health, see our VOS3000 monitoring guide.

📋 Metric	📋 Without NO_CDR	📋 With NO_CDR
CDR Inserts per Hour (10K free calls)	10,000	0
MySQL Disk I/O	High	Reduced proportionally
CDR Table Size Growth	Rapid	Slower
Query Performance	Degrades over time	More stable
Backup Size	Larger	Smaller
Billing Engine CPU Load	Higher (CDR write overhead)	Lower (skipped writes)

Wildcard Pattern Configuration Examples

The wildcard matching for VOS3000 no-CDR free numbers works identically to other billing parameters. The asterisk character matches any number of trailing digits, enabling efficient coverage of entire number ranges without listing each number individually.

📋 Pattern	📋 What It Matches	📋 Typical Use Case
5000*	All numbers starting with 5000	Internal test range
6000*	All numbers starting with 6000	PBX extension range
7000	Exact number 7000 only	Specific health-check number
8800*	All numbers starting with 8800	Automated probe range
9999*	All numbers starting with 9999	Internal service codes

Best Practices for Zero-Record Configuration

Implementing VOS3000 no-CDR free numbers requires careful planning to balance performance gains with operational visibility. Never use NO_CDR_E164S for numbers where you need any form of audit trail, dispute resolution capability, or regulatory reporting. Always pair it with proper monitoring to ensure the configuration remains correct over time.

📋 Best Practice	📋 Description
Reserve for truly disposable calls	Only skip CDR for calls with zero reporting value
Use specific wildcard patterns	Avoid overly broad patterns like 1* that could match billable numbers
Document all NO_CDR entries	Maintain a separate record of which numbers skip CDR and why
Review configuration quarterly	Ensure patterns still match intended numbers only
Test after every change	Verify CDR is properly skipped and billable calls still generate records
Keep emergency numbers on FREE_E164S	Emergency calls need an audit trail even if they are free

Frequently Asked Questions About VOS3000 No-CDR Free Numbers

What is SERVER_BILLING_NO_CDR_E164S in VOS3000?

SERVER_BILLING_NO_CDR_E164S is a VOS3000 server billing parameter that specifies E164 numbers or wildcard patterns for which CDR records should not be generated at all. When a called number matches any pattern in this list, the billing engine completely skips the CDR write operation, resulting in zero database record creation for that call. This differs from FREE_E164S which still creates a zero-charge CDR, making NO_CDR_E164S ideal for high-volume free-call scenarios where no audit trail is needed.

How is NO_CDR_E164S different from FREE_E164S?

The key difference is that FREE_E164S still generates a CDR record with a zero billing amount, while NO_CDR_E164S skips CDR generation entirely. With FREE_E164S, you retain a complete call audit trail showing that the call occurred with no charge. With NO_CDR_E164S, there is no record whatsoever — the call is invisible in CDR-based reports. Use FREE_E164S when you need tracking and compliance, and NO_CDR_E164S when you need maximum database performance for truly disposable calls.

When should I use VOS3000 no-CDR free numbers instead of zero-charge billing?

You should use VOS3000 no-CDR free numbers when the calls have zero reporting or audit value and are generated in high volumes that could impact database performance. Common examples include automated health-check probes, internal PBX extension calls, route testing numbers, and any repetitive system-generated calls where keeping records provides no business benefit. If regulatory compliance requires call tracking, or if you need dispute resolution data, use FREE_E164S instead to maintain the zero-charge CDR record.

Can I use both NO_CDR_E164S and FREE_E164S simultaneously?

Yes, you can configure both SERVER_BILLING_NO_CDR_E164S and SERVER_BILLING_FREE_E164S on the same VOS3000 server. They serve complementary purposes — FREE_E164S for numbers that need tracking with zero charges, and NO_CDR_E164S for numbers that should generate no record at all. However, you should avoid listing the same number in both parameters, as this could create ambiguous behavior. If a number appears in both lists, NO_CDR_E164S typically takes precedence, but it is best practice to ensure no overlap between the two lists.

How do I verify that CDR generation is being skipped?

To verify that VOS3000 no-CDR free numbers configuration is working correctly, place a test call to a number that matches your NO_CDR_E164S pattern, then query the CDR table in MySQL. You should find no record of that call at all. Compare this with a call to a normal billable number which should produce a CDR entry. You can use the VOS3000 CDR portal or direct MySQL queries to confirm. Refer to our VOS3000 CDR analysis and billing guide for help interpreting CDR records.

Does skipping CDR affect call routing or quality?

No, the SERVER_BILLING_NO_CDR_E164S parameter only affects the billing and CDR generation stage of call processing. It has no impact on call routing decisions, SIP signaling, codec negotiation, or audio quality. The call is routed and processed normally through the VOS3000 softswitch — the only difference is that the billing engine does not create a database record after the call completes. The call setup, media handling, and teardown processes remain completely unaffected by this configuration.

What happens if I accidentally add a billable number to NO_CDR_E164S?

If you add a billable number to the NO_CDR_E164S list, calls to that number will not generate any CDR record, meaning you will lose all billing data for those calls. This can result in revenue leakage because there will be no record to bill against. This is why it is critical to use specific wildcard patterns rather than overly broad ones, document all entries, and review the configuration regularly. Always test with a small pattern first and verify that only intended numbers are affected before deploying broadly.

April 19, 2026April 19, 2026 king

VOS3000 Toll-Free E164 Billing Complete Free Number Configuration

Understanding VOS3000 toll-free E164 billing is essential for any VoIP operator who needs to route emergency and toll-free calls without applying charges. The SERVER_BILLING_FREE_E164S parameter in VOS3000 allows administrators to designate specific E164 numbers or wildcard patterns that incur zero billing cost, ensuring compliance with regulatory requirements and proper handling of free-call destinations. Need help configuring this? Contact us on WhatsApp: +8801911119966.

Toll-free numbers such as 1-800 series in North America, 0800 in Europe, and emergency numbers like 911 or 112 must never be billed to the caller. VOS3000 provides a dedicated configuration mechanism to handle these scenarios cleanly within the billing engine, preventing accidental rating of calls that should always remain free.

VOS3000 Toll-Free E164 Billing Parameter Overview

The SERVER_BILLING_FREE_E164S parameter is defined in the VOS3000 server billing configuration file. It accepts a comma-separated list of E164 number patterns. When an outbound call matches any pattern in this list, the billing engine skips the rating process entirely for that call leg, resulting in a zero-charge record. This is documented in section §4.3.5.1 of the VOS3000 administration manual.

📋 Parameter	📋 Value
Parameter Name	SERVER_BILLING_FREE_E164S
Configuration File	mbx2008.conf or server billing config
Data Type	Comma-separated E164 patterns
Default Value	Empty (no free numbers defined)
Wildcard Support	Yes (asterisk * for prefix matching)
Manual Section	§4.3.5.1

Configuration Syntax for Free E164 Numbers

Setting up VOS3000 toll-free E164 billing requires editing the server configuration and specifying number patterns. Each entry can be an exact E164 number or a wildcard pattern using the asterisk character to match any suffix.

📋 Syntax Element	📋 Description	📋 Example
Exact Number	Matches one specific E164	18001234567
Prefix Wildcard	Matches all numbers starting with prefix	1800*
Multiple Entries	Comma-separated list	1800,0800,911

Use Cases for Free Number Billing Exemption

The VOS3000 toll-free E164 billing exemption serves several critical use cases in production VoIP environments. Understanding when and why to apply these configurations helps operators maintain both regulatory compliance and billing accuracy.

📋 Use Case	📋 Description	📋 Example Numbers
Emergency Services	Must never be billed per regulation	911, 112, 999, 000
Toll-Free Hotlines	Business 800 numbers that absorb cost	1800, 1888, 0800*
Customer Support Lines	Internal no-charge support numbers	Custom operator prefixes
Interconnect Testing	Test numbers for route verification	Operator-assigned test E164s
Helpline Services	Crisis hotlines, poison control, etc.	Region-specific helpline E164s
Internal Extensions	On-net calls between PBX users	Internal dial plan patterns

FREE_E164S vs Standard Billing Comparison

It is important to understand how VOS3000 toll-free E164 billing differs from standard call rating. When a number matches the FREE_E164S list, the billing engine produces a CDR with a zero charge rather than applying the normal rate table lookup. The call still generates a record for tracking purposes, but the financial amount is always zero.

📋 Aspect	📋 Standard Billing	📋 FREE_E164S
Rate Table Lookup	Yes	Skipped
CDR Generated	Yes (with charges)	Yes (zero charge)
Billing Amount	Per rate table	Always 0.00
Call Tracking	Full tracking	Full tracking (zero cost)
Database Impact	Normal	Normal (CDR still written)

Frequently Asked Questions About VOS3000 Toll-Free E164 Billing

What is SERVER_BILLING_FREE_E164S in VOS3000?

SERVER_BILLING_FREE_E164S is a VOS3000 server configuration parameter that defines a list of E164 numbers or wildcard patterns for which no billing charges are applied. When a called number matches any pattern in this list, the billing engine bypasses rate table lookup and assigns a zero charge to the call. This parameter is essential for handling toll-free numbers, emergency services, and any call destinations that must remain free of charge for regulatory or business reasons.

How do I add multiple toll-free number ranges to VOS3000?

You can add multiple toll-free number ranges by specifying comma-separated E164 patterns in the SERVER_BILLING_FREE_E164S parameter value. For example, setting it to 1800*,1888*,0800*,911,112 will exempt all calls starting with 1800, 1888, 0800 as well as the exact emergency numbers 911 and 112 from billing. Each pattern is evaluated independently, and wildcard patterns using the asterisk character allow you to cover entire number ranges efficiently.

Does FREE_E164S still generate CDR records?

Yes, calls matching the FREE_E164S list still generate CDR records in VOS3000. The difference is that these CDR records will have a zero billing amount. This behavior allows operators to maintain full call tracking and reporting for toll-free and emergency calls while ensuring no charges are applied. If you need calls that generate no CDR at all, you should use the SERVER_BILLING_NO_CDR_E164S parameter instead, which skips CDR creation entirely.

Can I use wildcard patterns for toll-free number matching?

Yes, VOS3000 supports wildcard patterns using the asterisk character in the SERVER_BILLING_FREE_E164S configuration. The asterisk matches any number of trailing digits, allowing you to cover entire toll-free number ranges with a single entry. For example, 1800* matches any number beginning with 1800 followed by any additional digits, effectively covering the entire North American 1-800 toll-free range.

What happens if a number matches both a rate table and FREE_E164S?

When a called number matches the FREE_E164S list, the VOS3000 billing engine prioritizes the free number designation over the rate table. This means the call will be billed at zero regardless of what the rate table would normally return. The FREE_E164S check occurs before rate table lookup in the billing pipeline, ensuring that toll-free and emergency numbers are never accidentally charged even if they also exist in a rate table.

How do I verify my toll-free billing configuration is working?

To verify your VOS3000 toll-free E164 billing configuration, place a test call to a number that should match your FREE_E164S patterns and then check the generated CDR record. The CDR should show the call with a billing amount of zero. You can use the VOS3000 monitoring tools to inspect recent CDRs — refer to our VOS3000 monitoring guide for detailed steps. If the call still shows a charge, verify your pattern format matches the E164 format used in the CDR.

The operating system foundation is critical for VOS3000 server setup success. CentOS 7.x is the recommended platform for both VOS3000 2.1.8.05 and 2.1.9.07 versions. This section covers the essential preparation steps before installing VOS3000 software.

Step 1: Install Minimal CentOS 7

Begin with a minimal CentOS 7 installation. This provides a clean base without unnecessary packages that consume resources and create security vulnerabilities. During installation:

Select minimal installation type
Configure network with static IP address
Set appropriate timezone for your operations
Create non-root user for administrative tasks
Enable SSH for remote access (will be hardened later)

Step 2: Update System Packages

After installation, update all system packages to ensure security patches and bug fixes are applied:

# Update all packages
yum update -y

# Install essential utilities
yum install -y wget curl nano vim net-tools

# Install development tools (required for some VOS3000 components)
yum groupinstall -y "Development Tools"

Step 3: Configure Network Settings

Proper network configuration ensures your VOS3000 server setup handles VoIP traffic efficiently. Key parameters include:

# Edit sysctl configuration for VoIP optimization
nano /etc/sysctl.conf

# Add these parameters:
net.core.rmem_max = 16777216
net.core.wmem_max = 16777216
net.ipv4.tcp_rmem = 4096 87380 16777216
net.ipv4.tcp_wmem = 4096 65536 16777216
net.core.netdev_max_backlog = 5000
net.ipv4.tcp_max_syn_backlog = 8192
net.core.somaxconn = 1024
net.ipv4.ip_local_port_range = 1024 65535

# Apply changes
sysctl -p

These network optimizations improve packet handling for real-time voice traffic, reducing latency and preventing packet loss during peak traffic periods.

MySQL Configuration for VOS3000 Server Setup

The MySQL database is the heart of VOS3000 operations, storing CDR records, account information, rate tables, and configuration data. Proper MySQL configuration is essential for VOS3000 server setup performance.

Install MySQL Server

VOS3000 requires MySQL 5.7 for optimal compatibility. Install and configure as follows:

# Add MySQL repository
yum localinstall -y https://dev.mysql.com/get/mysql57-community-release-el7-11.noarch.rpm

# Install MySQL server
yum install -y mysql-community-server

# Start MySQL and enable auto-start
systemctl start mysqld
systemctl enable mysqld

# Get temporary root password
grep 'temporary password' /var/log/mysqld.log

Optimize MySQL for VoIP Workload

Default MySQL configuration is not suitable for VOS3000 workloads. Create an optimized configuration file:

⚙️ Parameter	📊 Recommended Value	📝 Purpose
innodb_buffer_pool_size	50-70% of RAM	Caches table data for fast queries
max_connections	500-1000	Handles concurrent connections
innodb_log_file_size	256M – 512M	Transaction log size
query_cache_size	64M – 128M	Caches repeated queries
tmp_table_size	64M – 128M	Temporary table handling

Apply these settings in /etc/my.cnf and restart MySQL. For detailed MySQL optimization guidance, refer to our MySQL backup and restore guide.

Security Hardening in VOS3000 Server Setup

Security is not optional for VoIP platforms. A comprehensive VOS3000 server setup must include multiple security layers to protect against various attack vectors. This section covers essential security measures.

Configure Firewall Rules

The firewall is your first line of defense. Configure iptables to allow only necessary traffic:

# Flush existing rules
iptables -F

# Allow loopback
iptables -A INPUT -i lo -j ACCEPT
iptables -A OUTPUT -o lo -j ACCEPT

# Allow established connections
iptables -A INPUT -m state --state ESTABLISHED,RELATED -j ACCEPT

# Allow SSH (change port for security)
iptables -A INPUT -p tcp --dport 22 -j ACCEPT

# Allow SIP signaling
iptables -A INPUT -p udp --dport 5060 -j ACCEPT
iptables -A INPUT -p tcp --dport 5060 -j ACCEPT

# Allow RTP media ports (adjust range as needed)
iptables -A INPUT -p udp --dport 10000:20000 -j ACCEPT

# Allow web interface
iptables -A INPUT -p tcp --dport 80 -j ACCEPT
iptables -A INPUT -p tcp --dport 8080 -j ACCEPT

# Drop everything else
iptables -A INPUT -j DROP

# Save rules
service iptables save

Install and Configure Fail2Ban

Fail2Ban automatically blocks IP addresses that show malicious activity, such as repeated failed login attempts:

# Install Fail2Ban
yum install -y epel-release
yum install -y fail2ban

# Create custom configuration
nano /etc/fail2ban/jail.local

# Add configuration for SSH protection

[sshd]

enabled = true port = ssh filter = sshd logpath = /var/log/secure maxretry = 3 bantime = 3600 # Start and enable systemctl start fail2ban systemctl enable fail2ban

Many operators who search for “voss switch” security tips overlook these basic protections. Our extended firewall guide provides additional security configurations.

VOS3000 Number Transform Powerful Configuration – Caller ID & Prefix Rules

April 10, 2026April 10, 2026 king

VOS3000 Number Transform Powerful Configuration – Caller ID & Prefix Rules

VOS3000 number transform functionality provides comprehensive control over how telephone numbers are manipulated during call processing, enabling operators to modify caller IDs, transform called numbers, and implement complex routing rules based on number patterns. The number transformation capabilities documented in the VOS3000 2.1.9.07 manual represent essential tools for any VoIP service provider seeking to normalize number formats, implement proper routing, and ensure compatibility between different network elements. Understanding and correctly configuring number transformation ensures calls are properly routed, billing is accurate, and regulatory compliance requirements are met.

The VOS3000 softswitch processes telephone numbers at multiple stages during call handling, from initial reception through routing decisions to final delivery. At each stage, number transformation rules can be applied to modify the number format, add or remove prefixes, translate between different numbering schemes, and ensure proper presentation. The VOS3000 number transform system supports both simple prefix operations and complex pattern-based transformations using regular expressions. For technical assistance with number transformation configuration, contact us on WhatsApp at +8801911119966.

Understanding Number Transformation in VOS3000

Number transformation in VOS3000 refers to the systematic modification of telephone numbers during call processing. The VOS3000 2.1.9.07 manual documents this functionality in Section 2.13.3, providing the foundation for understanding how transformation rules work and how they should be configured. (VOS3000 Number Transform)

Why Number Transformation Matters

Telephone numbers arrive at your VOS3000 platform from various sources with different formats and conventions. Some callers dial numbers with country codes, others without. Some systems send numbers with leading zeros, others with plus signs. Vendor connections may expect numbers in specific formats. Number transformation enables your platform to normalize these variations into consistent formats for routing and billing purposes.

Key reasons for implementing number transformation include ensuring consistent routing decisions regardless of input format, maintaining billing accuracy with properly normalized numbers, meeting vendor requirements for number format, implementing caller ID policies and compliance, and supporting multiple dialing conventions simultaneously. (VOS3000 Number Transform)

Transformation Points in VOS3000 (VOS3000 Number Transform)

The VOS3000 manual documents number transformation at multiple configuration points:

Number Transform Table: Section 2.13.3 documents the dedicated number transformation table that defines transformation rules used throughout the system
Gateway Configuration: Both routing gateways and mapping gateways can apply transformation rules
Dial Plans: Section 4.3.1 documents dial plan functionality for number manipulation
Caller Transform: Specifically transforms caller IDs using transformation table entries
Callee Transform: Specifically transforms called numbers using transformation table entries

📖 Manual Section	📋 Function	📞 Application
2.13.3 Number Transform	Transformation table management	Define transformation rules
2.5.1 Routing Gateway	Vendor gateway settings	Apply transforms to outbound
2.5.1.2 Mapping Gateway	Customer gateway settings	Apply transforms to inbound
4.3.1 Dial Plan	Number manipulation rules	Pattern-based transformation

Accessing the Number Transform Configuration

The VOS3000 manual provides clear instructions for accessing the number transformation functionality. According to Section 2.13.3, the function is used to manage number transform rules that can be applied throughout the system.

Navigation Path

According to the manual: “Double-click Navigation > Number management > Number transform” to access the transformation table. This centralized table stores transformation rules that can be referenced by various system components including gateways and dial plans.

Transformation Table Structure

The number transformation table contains entries that define how specific numbers or patterns should be transformed. Each entry specifies the original number or pattern to match and the replacement value. When calls are processed, the system checks applicable transformation rules and applies matching transformations.

Caller Transform Configuration

The VOS3000 number transform functionality includes specific support for caller ID transformation. According to the manual documentation on gateway configuration, “Caller transform: use number in ‘Number Transformation’ table to replace caller ID.”

How Caller Transform Works

When caller transform is enabled on a gateway, the system looks up the caller ID in the number transformation table. If a matching entry is found, the caller ID is replaced with the transformation result. This enables systematic manipulation of calling numbers based on configured rules.

Common use cases for caller transform include adding country codes to inbound caller IDs for consistent routing, replacing specific caller IDs for privacy or compliance, normalizing caller ID formats from different sources, and implementing caller ID pooling strategies.

Enabling Caller Transform

Caller transform is configured in the gateway additional settings. When enabled, the gateway references the number transformation table to determine if any transformations should be applied to caller IDs. The transformation occurs before routing decisions are made, ensuring all downstream processing sees the transformed value. (VOS3000 Number Transform)

📞 Use Case	⚙️ Original Value	✅ Transformed Value
Add country code	2015551234	12015551234
Remove leading zero	0044123456789	44123456789
Replace specific number	1234567890	0987654321
Format with prefix	5551234	+12015551234

Callee Transform Configuration

Similar to caller transform, VOS3000 supports callee (called number) transformation. The manual documents: “Callee transform: use number in ‘Number Transformation’ table to replace callee ID.”

How Callee Transform Works

Callee transform modifies the destination number during call processing. This is particularly useful for number normalization before routing, implementing number portability corrections, translating between numbering formats, and handling special number cases.

When a call arrives with a called number, the system checks if callee transform is enabled on the relevant gateway. If so, the number transformation table is consulted, and any matching transformation is applied. This ensures routing and billing use the corrected destination number.

Common Callee Transformation Scenarios

Destination number transformation addresses several common scenarios:

Emergency Number Handling: Transform emergency numbers (911, 112, etc.) to appropriate routing codes
Toll-Free Normalization: Standardize toll-free number formats (800, 888, etc.)
International Format: Convert local formats to international E.164 format
Area Code Handling: Add or modify area codes based on routing requirements
Short Code Translation: Expand short codes to full routing numbers

Dial Plan Integration with Number Transform

The VOS3000 number transform functionality integrates closely with the dial plan system documented in manual Section 4.3.1. Dial plans provide pattern-based number manipulation capabilities that complement the number transformation table.

Dial Plan Fundamentals

According to the manual, dial plans define how numbers are manipulated during call processing. Dial plans can be applied to both caller and called numbers, providing another mechanism for number transformation beyond the dedicated transformation table.

Routing Caller Dial Plan

The manual documents: “Routing caller dial plan: change dial plans for the caller number when called out through this gateway.”

This setting applies dial plan transformations to the caller ID when calls exit through a specific routing gateway. Each gateway can have different dial plans, enabling format customization for different vendor requirements. (VOS3000 Number Transform)

Caller Dial Plan in P-Asserted-Identity

The manual also documents: “Caller dial plan: dial plans for the caller number in ‘P-Asserted-Identity’ field.”

This relates to handling caller ID in SIP P-Asserted-Identity headers, which is important for carrier interconnection requirements and regulatory compliance with caller ID verification systems.

📍 Application Point	📋 Description	💡 Use Case
Routing Caller Dial Plan	Transform caller on outbound	Vendor format requirements
Routing Callee Dial Plan	Transform called on outbound	Destination normalization
Mapping Caller Dial Plan	Transform caller on inbound	Customer format handling
Mapping Callee Dial Plan	Transform called on inbound	Number normalization

VOS3000 Number Transform Configuration Best Practices

Implementing effective VOS3000 number transform configuration requires careful planning and adherence to best practices. These recommendations help ensure transformations work correctly and do not cause unintended issues.

📏 Maintain Format Consistency

Choose a standard number format for internal processing and ensure all transformations work toward that format. E.164 international format is recommended for most applications because it provides unambiguous number representation. Configure inbound transformations to convert all incoming numbers to your standard format, and outbound transformations to meet vendor format requirements.

🔧 Test Transformations Thoroughly

Before deploying transformation rules in production, test them with a variety of number formats and edge cases. Verify that transformations produce expected results for typical numbers, numbers with unusual formats, emergency and special service numbers, international numbers with various country codes, and numbers with leading zeros or other variations.

📋 Document Transformation Rules

Maintain clear documentation of all transformation rules, including the purpose of each rule, expected input formats, output format requirements, related gateway configurations, and any dependencies on other rules. This documentation proves invaluable when troubleshooting issues or training new administrators.

🔒 Consider Security Implications

Number transformation has security implications that should be considered:

Ensure transformations do not inadvertently expose private caller IDs
Verify that transformations comply with caller ID regulations in your jurisdiction
Monitor for attempts to manipulate caller ID for fraudulent purposes
Implement appropriate access controls on transformation configuration

Troubleshooting Number Transform Issues

When VOS3000 number transform configuration does not work as expected, systematic troubleshooting helps identify and resolve problems.

📞 Transformation Not Applied

If transformations are not being applied:

Verify the transformation table contains the correct entries
Check that caller/callee transform is enabled on the relevant gateway
Confirm the number format matches the transformation rule pattern
Verify there are no conflicting transformation rules
Check gateway additional settings for transform configuration

🔄 Wrong Transformation Applied

If incorrect transformations occur:

Review transformation rule priority and matching logic
Check for multiple rules matching the same number
Verify the transformation table entries are correct
Examine the order of transformations if multiple apply
Use debug trace to see actual transformation behavior

📊 Billing Discrepancies After Transformation

If billing shows unexpected numbers:

Verify transformation occurs before billing record creation
Check rate tables are configured for transformed number formats
Confirm area prefix settings match transformed numbers
Review CDR to see what numbers were recorded

⚠️ Issue	🔍 Possible Cause	✅ Solution

Advanced Number Transform Techniques

Beyond basic transformation, VOS3000 supports advanced techniques for complex number manipulation requirements.

Conditional Transformation

Transformations can be made conditional based on gateway, time, or other factors by configuring different gateways with different transformation settings. For example, calls from specific customers can have their numbers transformed differently by using separate mapping gateways with distinct transformation configurations.

Multi-Stage Transformation

Numbers can be transformed multiple times during call processing. A number might be normalized on inbound through a mapping gateway transformation, then formatted for a specific vendor through a routing gateway transformation. Understanding this processing pipeline is essential for complex configurations.

Integration with Black/White Lists

The VOS3000 manual documents black/white list functionality in Section 2.13.4-2.13.6. Number transformation works in conjunction with these features, as the transformed numbers are what get checked against black and white list entries. Ensure transformations produce numbers that match your list configurations.

Frequently Asked Questions About VOS3000 Number Transform

❓ How do I add a country code to all inbound caller IDs?

Create entries in the Number Transform table that match numbers without country codes and add the appropriate prefix. Then enable caller transform on your mapping gateways to apply these transformations to inbound caller IDs.

❓ Can I use regular expressions in number transformation?

VOS3000 supports pattern-based matching in dial plans and transformation rules. Refer to Section 4.3.1 of the manual for dial plan syntax details. The transformation table supports matching specific numbers and patterns.

❓ What happens if multiple transformation rules match?

The system processes transformation rules according to configured order and matching logic. Be careful to avoid conflicting rules that could produce unexpected results. Test thoroughly with production-like number formats.

❓ How do I test transformation rules before deploying?

Use the debug trace functionality documented in Section 2.17.1 to monitor call processing and see actual transformation behavior. Start with test calls to verify transformations work correctly before processing production traffic.

❓ Do transformations affect billing records?

Yes, transformations are typically applied before billing records are created. Ensure your rate tables are configured for the transformed number formats. Review CDR records to verify correct number formats are being recorded.

❓ Can I transform numbers differently for different vendors?

Yes, configure different routing gateways with different transformation settings. Each gateway can have its own dial plans and transform configurations, enabling vendor-specific number formatting.

VOS3000 Caller ID Management: Complete CLI Configuration Guide

VOS3000 caller ID management provides comprehensive control over how calling numbers are handled, displayed, and routed through your VoIP softswitch platform. Caller ID, also known as CLI (Calling Line Identification), plays a crucial role in call routing decisions, billing accuracy, regulatory compliance, and customer experience. Understanding the caller ID management capabilities documented in the VOS3000 2.1.9.07 manual enables operators to configure their systems for optimal performance while maintaining compliance with telecommunications regulations.

The VOS3000 platform offers multiple mechanisms for caller ID handling, from simple passthrough to complex transformation rules. These features are documented across several sections of the official manual, including gateway configuration parameters, routing prefix settings, and number transformation capabilities. Proper VOS3000 caller ID management ensures calls are properly identified, routed, and billed while meeting regulatory requirements for caller identification. For technical support with caller ID configuration, contact us on WhatsApp at +8801911119966.

Understanding Caller ID in VOS3000

Before configuring caller ID settings, understanding how VOS3000 processes calling numbers provides the foundation for proper configuration. The system handles caller ID at multiple points in the call flow, from initial reception through routing to final delivery.

Caller ID Processing Points (VOS3000 Caller ID Management)

VOS3000 processes caller ID information at several stages:

Inbound Reception: When calls arrive from customers or mapping gateways
Routing Decision: When determining how to route calls
Outbound Transmission: When sending calls to vendors or routing gateways
CDR Recording: When logging call details for billing

Manual Reference Points

Caller ID functionality is documented in multiple VOS3000 manual sections:

📖 Manual Section	📋 Function	📞 CLI Relevance
2.5.1 Routing Gateway	Vendor gateway settings	Caller prefix, caller rewrite
2.5.1.2 Mapping Gateway	Customer gateway settings	Caller rewrite rules
2.5.2 Phone Management	Phone/extension settings	Display caller ID
4.3.5 Softswitch Parameters	System-wide settings	Caller ID extraction

Caller Number Allowable Length Configuration

One of the fundamental VOS3000 caller ID management features is the ability to control which caller numbers are allowed based on their length. According to the manual Section on Additional settings > Others, this provides security and routing control.

Configuration Location

The manual documents “Caller number allowable length” as: “the lengths of the caller numbers allowed to pass through the gateway (e.g. fill in ’11, 14′ to allow numbers of 11 digits or 14 digits only).”

Practical Application

This setting allows operators to:

Filter out invalid caller IDs (too short or too long)
Enforce national numbering plan compliance
Prevent spoofed caller IDs with unusual lengths
Control traffic by caller ID format

⚙️ Configuration	📋 Result	💡 Use Case
Blank	Allow all lengths	No restriction
11	Only 11-digit numbers	US/Canada mobile format
10, 11	10 or 11-digit numbers	US numbers with/without 1
0	Block all numbers	Emergency blocking

Caller Transform Configuration (VOS3000 Caller ID Management)

The VOS3000 manual documents “Caller transform” functionality that allows replacing caller ID using the “Number Transformation” table. This feature enables systematic caller ID modification for routing and compliance purposes.

How Caller Transform Works

According to the manual: “Caller transform: use number in ‘Number Transformation’ table to replace caller ID.”

This feature enables:

Standardizing caller ID formats
Adding or removing prefixes
Replacing specific numbers
Implementing number pooling

Number Transformation Table

The Number Transformation table (accessed via Number Management functions) defines transformation rules that can be applied to caller IDs. Each rule specifies:

Original number or pattern
Replacement number or pattern
Application scope

Routing Caller Prefix Configuration (VOS3000 Caller ID Management)

For routing gateways (vendor connections), VOS3000 provides caller prefix controls documented in the Additional settings > Routing prefix section of the manual.

Routing Caller Prefix Settings

The manual documents two modes for Routing caller prefix:

Allow: “prefixes of the caller numbers allowed to pass through (left blank to allow all numbers).”

Forbidden: “prefixes of the caller numbers disallowed to pass through.”

Importantly, “Only one of the ‘Allow’ and ‘Forbidden’ options can be chosen.”

⚙️ Mode	📋 Behavior	💡 Example
Allow	Only specified prefixes pass	Allow 1,44,86 – only US, UK, China callers
Forbidden	Specified prefixes blocked	Forbidden 88 – block Bangladesh prefix
Allow (blank)	All prefixes pass	No restriction on caller prefix

Caller Dial Plan Configuration (VOS3000 Caller ID Management)

The VOS3000 manual documents caller dial plan functionality in multiple contexts. Dial plans define how numbers are transformed during call processing.

Routing Caller Dial Plan

According to the manual: “Routing caller dial plan: change dial plans for the caller number when called out through this gateway.”

This setting applies dial plan transformations to the caller ID when calls exit through a specific routing gateway, enabling:

Format standardization for specific vendors
Country code handling
Area code manipulation

Caller Dial Plan in P-Asserted-Identity

The manual also documents: “Caller dial plan: dial plans for the caller number in ‘P-Asserted-Identity’ field.”

This relates to handling caller ID in SIP P-Asserted-Identity headers, which is important for:

Carrier interconnection requirements
Regulatory compliance
Caller ID verification systems

Display Caller ID Configuration (VOS3000 Caller ID Management)

For phone management (retail/SIP accounts), VOS3000 provides display caller ID controls. According to the manual Section 2.5.2, this controls what caller ID is shown at the called end.

Display Caller ID Settings

The manual documents: “Display caller id: the caller ID shown at the called end.”

Additionally: “Display caller id: display the caller’s ID.”

Enable Phone Display Number

For mapping gateways, the manual documents: “Enable phone display number: when caller is phone, check to use phone’s display number, uncheck to use phone number.”

This setting determines whether:

The phone’s configured display number is used as caller ID
The actual phone number (registration ID) is used as caller ID

Caller Rewrite Rules (VOS3000 Caller ID Management)

VOS3000 provides caller rewrite rules for both mapping gateways (customers) and routing gateways (vendors). These rules enable systematic transformation of caller IDs.

Mapping Gateway Caller Rewrite Rules

For customer-facing mapping gateways, caller rewrite rules process inbound caller IDs from customers. The manual documents this in gateway configuration settings.

Common uses include:

Adding country codes to inbound caller IDs
Removing leading digits
Standardizing formats

Routing Gateway Caller Rewrite Rules

For vendor-facing routing gateways, caller rewrite rules process outbound caller IDs sent to vendors.

📝 Rule Type	📋 Application	💡 Example
Add Prefix	Prepend digits to caller ID	Add 1 to US numbers
Remove Prefix	Strip leading digits	Remove 00 international prefix
Replace	Substitute specific numbers	Replace specific caller ID

Caller Number Pool Configuration

VOS3000 supports caller number pools for providing rotating or shared caller IDs. This is documented in gateway additional settings.

Enable Caller Number Pool

According to the manual: “Enable caller number pool: use number in pool as caller.”

And: “Enable forwarding signal caller pool: use number in pool as caller.”

Multiplexes Setting

The manual documents: “Multiplexes: the number of repeated uses of each number in the calling number pool is the maximum concurrency limit.”

This setting controls how many concurrent calls can use the same number from the pool, important for:

Managing caller ID capacity
Preventing overuse of specific numbers
Compliance with carrier requirements

Caller ID Source Configuration

VOS3000 allows configuration of which SIP field is used to extract the caller ID. This is documented in softswitch parameter settings.

Caller ID Field Selection

The manual documents options for extracting caller ID from SIP signaling:

From: “get caller number from ‘From’ of signal”
Remote-Party-ID: “get caller number from ‘Remote-Party-ID’ of signal”
Display: “get caller number from ‘Display’ of signal”

The “Caller” setting: “get caller number from which field of signal.”

Peer Number Information

The manual documents: “Peer number information: set select mode to SIP signal’s caller.”

This setting affects how the system identifies the caller in SIP signaling.

📡 SIP Field	📋 Typical Use	💡 Consideration
From Header	Standard SIP caller ID	Most common choice
Remote-Party-ID	Carrier-provided CLI	Used by some carriers
Display Name	Display-only caller ID	May differ from routing ID

Phone Number as Caller ID

In phone management, VOS3000 uses phone numbers as caller IDs. The manual documents this functionality.

Phone Number Configuration

According to the manual: “Phone number: the number used as caller ID and the called number for the terminal.”

And further: “Phone number: the number used by the terminal at registration (used as the caller ID and…”

This establishes the phone number as both:

The registration identifier
The default caller ID for outbound calls

DID/DDI Configuration

The manual documents DID/DDI functionality: “DID/DDI: after the phone on line, the other numbers allowed as caller ID or callee.”

This allows phones to use multiple numbers as caller IDs, useful for:

Multi-line appearances
Department numbers
Geographic numbers

Caller Prefix Control

VOS3000 provides caller prefix control for both mapping and routing gateways. This allows fine-grained control over which caller prefixes are allowed.

Caller Prefix Control on Gateways

The manual documents for mapping gateways: “Caller prefix control: allow or forbidden caller prefix to get through this gateway.”

This feature enables:

Allowing only specific caller prefixes
Blocking specific caller prefixes
Per-gateway caller ID filtering

Caller Dial Plan by Caller Prefix

The manual documents: “By caller: matches the prefixes of the caller numbers.”

This enables caller-prefix-based routing and dial plan application.

Configuration Best Practices

Following best practices ensures VOS3000 caller ID management is configured correctly and compliantly.

📏 Consistency in Format

Maintain consistent caller ID formats throughout your configuration:

Choose E.164 or local format and apply consistently
Document your chosen format
Verify format handling in rewrite rules

🔒 Security Considerations

Caller ID management has security implications:

Use caller prefix filtering to block known fraud sources
Validate caller ID lengths to catch anomalies
Monitor for caller ID manipulation attempts
Log caller ID changes for audit trails

📋 Compliance Requirements

Many jurisdictions have caller ID regulations:

Ensure accurate caller ID transmission
Prevent caller ID spoofing where prohibited
Maintain caller ID records for required periods
Follow local telecommunications regulations

🔗 Recursos Relacionados (VOS3000 Dial Plan Transformación)

❓ Preguntas Frecuentes sobre VOS3000 Dial Plan

¿Cuál es la diferencia entre Dial Plan y Number Transform?

El dial plan se aplica dinámicamente durante el routing de llamadas y puede variar por gateway, mientras que Number Transform es una configuración global que transforma números de manera sistemática. El dial plan ofrece mayor flexibilidad por permitir diferentes reglas para diferentes gateways o escenarios de routing.

¿Cómo puedo verificar si mi dial plan está funcionando correctamente?

La mejor manera es revisar los registros CDR comparando los campos “Incoming caller/callee” con “Outbound caller/callee”. También puede usar la función de Call Analysis en Current Call para ver la transformación en tiempo real. Los números deben mostrar la transformación aplicada según las reglas configuradas.

¿Qué sucede si tengo múltiples dial plans que coinciden con un número?

VOS3000 aplica el principio de coincidencia más larga. Si tiene un dial plan que transforma “0” y otro que transforma “010”, para el número “01012345678” se aplicará la regla “010” porque tiene la coincidencia más larga. El patrón “*” solo se aplica cuando no hay otras coincidencias.

¿Puedo usar dial plan para cambiar el caller ID que ven los destinatarios?

Sí, el Outbound Caller Dial Plan permite modificar el número de identificación del llamante que se presenta al destinatario. Esto es útil para presentar números locales en diferentes regiones o para propósitos de marca blanca en servicios wholesale.

¿El dial plan afecta la facturación de las llamadas?

Sí, es importante considerar que el dial plan transforma el número antes del billing. Asegúrese de que el número transformado coincida con los prefijos de tarifa configurados en su sistema. Un dial plan mal configurado puede causar que las llamadas no se facturen correctamente.

¿Cómo funcionan los caracteres de escape L, E, G?

Estos caracteres permiten crear reglas basadas en la longitud del número. L (Less) especifica números más cortos que el valor, E (Equal) números exactamente del largo especificado, y G (Greater) números más largos. Por ejemplo, “13L9” coincide con números de 11 dígitos que empiezan con 13.

🔍 Understanding VOS3000 Dial Plan

The dial plan in VOS3000 provides a flexible mechanism for transforming phone numbers before routing and billing. When a call is processed, VOS3000 can apply dial plan rules to modify the called number (callee) or calling number (caller) based on pattern matching and substitution rules.

📊 Dial Plan Application Points

Reference: VOS3000 2.1.9.07 Manual, Section 4.3.1 (Page 219-220)

Application Point	Location	Purpose	Affects
Mapping Gateway Dial Plan	Mapping Gateway > Additional settings	Transform incoming called number	Number before routing decision
Routing Gateway Dial Plan	Routing Gateway > Additional settings	Transform outgoing called number	Number sent to downstream gateway
Phone Dial Plan	Phone Management > Additional settings	Transform called number for phone	Number before routing from phone

📐 Dial Plan Syntax and Wildcards

Reference: VOS3000 2.1.9.07 Manual, Section 4.3.1 (Page 219-220)

🔤 Wildcard Characters

VOS3000 dial plan supports wildcard characters for flexible pattern matching:

Wildcard	Name	Matches	Example
*	Asterisk	Any number of any digits (including zero)	* matches any number
?	Question Mark	Single random digit (in target prefix only)	123?78 matches 123178, 123278, etc.
$	Dollar Sign	Keep original digit at position (in target only)	$$$ keeps first three digits unchanged

🔧 Escape Characters for Length Constraints

VOS3000 dial plan supports escape characters to specify number length constraints:

Escape Char	Meaning	Syntax	Example
L	Length Less Than	Prefix followed by L and digit count	13L9 matches 11-digit numbers starting with 13
E	Length Equal To	Prefix followed by E and digit count	010E7 matches exactly 10 digits starting with 010
G	Length Greater Than	Prefix followed by G and digit count	010G7 matches 11+ digits starting with 010

Note: Use backslash before escape character (\L, \E, \G) to remove its special meaning and match literally.

📋 Complete Dial Plan Examples from Manual

Reference: VOS3000 2.1.9.07 Manual, Table 4-1 (Page 219-220)

📊 Dial Plan Transformation Table (VOS3000 Dial Plan)

🔀 Longest Matching Principle (VOS3000 Dial Plan)

Reference: VOS3000 2.1.9.07 Manual, Section 4.3.1 (Page 220)

When multiple dial plan rules exist, VOS3000 uses the longest matching principle to select which rule to apply. This ensures that more specific patterns take precedence over generic ones.

📊 Longest Matching Examples (VOS3000 Dial Plan)

Dial Plan Rules	Input Number	Matched Rule	Result	Reason
0 → 0 010 → 025	01012345678	010 → 025	02512345678	010 is longer match than 0
* → 025* 01 → 00	0112345678	01 → 00	0012345678	01 is longer match than *
0 → 0 01 → 025 011 → 00	01117654321	011 → 00	0017654321	011 is longest matching prefix

Important: The pattern “*” has the lowest priority and will only be matched when no other pattern matches. This makes it useful as a “default” rule.

🔧 Multiple Substitution Targets

VOS3000 dial plan supports multiple substitution targets separated by semicolons (;). When “?” exists in the target, each “?” is replaced by a randomly generated digit.

📋 Multiple Target Examples

Multiple Substitution Target Examples:
======================================

Target: 12345678;8008100-8008121;12345?78

This means randomly choose ONE of:
- 12345678 (constant)
- Any number from 8008100 to 8008121 (range)
- 12345?78 where ? is a random digit (pattern)

Result Examples:
- 12345678
- 8008105
- 8008119
- 12345178
- 12345878

Use Cases:
==========
1. Load balancing across multiple destination numbers
2. A/B testing different routes
3. Redundancy with fallback numbers
4. Random selection for pool allocation

⚙️ Dial Plan Configuration in VOS3000

📍 Configuring Mapping Gateway Dial Plan (VOS3000 Dial Plan)

Reference: VOS3000 2.1.9.07 Manual, Section 2.5.1.1 (Page 28-32)

Step-by-Step Mapping Gateway Dial Plan Configuration:
=====================================================

1. Navigate to:
   Navigation > Operation management > Gateway operation > Routing gateway

2. Right-click gateway and select "Additional settings"

3. Find "Callee number transform" section:
   - Callee number transform: Original prefix → Target prefix
   - Multiple rules separated by comma

4. Example Configuration:

   Target: (empty)

   Effect: Remove 00 prefix from incoming calls

5. Apply changes and test

Example Scenarios:
==================

Scenario 1: International calls coming with 00 prefix
Need to route to gateway expecting numbers without 00
Solution: Original: 00, Target: (leave empty)

Scenario 2: Local calls coming without area code
Need to add area code for routing
Solution: Original: *, Target: 025* (adds 025 prefix to all)

Scenario 3: Convert mobile prefix
Solution: Original: 013, Target: 8613 (convert Chinese mobile format)

📍 Configuring Routing Gateway Dial Plan

Reference: VOS3000 2.1.9.07 Manual, Section 2.5.1.1 (Page 32-39)

Setting	Location	Purpose
Callee number transform	Routing Gateway > Additional settings > Dial plan	Transform called number before sending to this gateway

Change area code	025	010	02584316146 → 01084316146

🚨 Emergency Number Routing

Emergency Number Dial Plan Examples:
====================================

Scenario: Route emergency numbers to specific gateway

1. Emergency 911/112 routing:
   Create routing gateway with prefix: 911,112
   Dial plan on mapping gateway:
   - Original: 911, Target: (empty - pass through)
   - Original: 112, Target: 911 (convert 112 to 911)

2. Police emergency:
   Original: 110
   Target: (empty or specific routing number)

3. Ambulance/Medical:
   Original: 120
   Target: (routing destination)

Important Notes:
================
- Emergency numbers should have highest priority
- Use specific prefixes (not wildcards) for emergency routing
- Test thoroughly before production deployment

🔍 Troubleshooting Dial Plan Issues

🚨 Common Problems and Solutions

Problem	Possible Cause	Solution
Number not matching expected rule	Longer pattern exists and takes precedence	Review all dial plan rules, use longest matching principle
Prefix not removed	Original prefix doesn’t match exactly	Verify exact prefix in CDR, adjust dial plan
Wrong transformation applied	Multiple rules with overlapping patterns	Check longest matching, reorder if needed
Billing discrepancy	Dial plan changes number after billing lookup	Verify dial plan application point (before/after billing)
Number becomes empty	Target prefix is empty for full match	Use correct wildcard patterns, avoid deleting entire number

📋 Dial Plan Testing Procedure

Dial Plan Testing Steps:
========================

1. Enable Debug Trace:
   System > Debug trace > Check "On"

2. Make Test Call:
   Place call with number to test

3. View Call Analysis:
   CDR > Right-click failed call > Call analysis

4. Check Number Transformation:
   - Look for "called number" before and after transformation
   - Verify correct dial plan was applied

5. Check CDR:
   - Verify "callee billing" shows correct number
   - Compare with "callee access" for incoming number

6. Adjust if needed:
   - Modify dial plan rules
   - Re-test with new configuration

❓ Frequently Asked Questions

What happens when multiple dial plan rules match?

VOS3000 applies the longest matching principle. The dial plan rule with the longest matching prefix is selected. For example, if you have rules for “0” and “010”, the number “01012345678” will match “010” because it’s longer. The “*” wildcard has the lowest priority.

Can I use dial plan to change caller ID?

Yes, VOS3000 supports caller number transformation in routing gateway settings. Configure “Caller number transform” in the routing gateway’s additional settings to modify the calling party number before sending to the downstream gateway.

How do I test if my dial plan is working correctly?

Enable debug trace in VOS3000, make a test call, then check the CDR and call analysis. The call analysis will show the number before and after transformation, confirming which dial plan rule was applied.

Can dial plan affect billing?

Yes, dial plan can affect billing if applied before the rate lookup. Mapping gateway dial plan transforms numbers before billing, while routing gateway dial plan transforms numbers after billing. Consider this when designing your number transformation strategy.

What’s the difference between gateway prefix and dial plan?

Gateway prefix is used for routing decisions – it determines which gateway handles the call. Dial plan transforms the actual number. Gateway prefix matching happens first for route selection, then dial plan transforms the number for the selected gateway.

Advanced Routing, LCR & Profit Control in VOS3000 – Real Examples & Settings 2026

Running a profitable VoIP business with VOS3000 requires precise control over call routing. The built-in Least Cost Routing (LCR), prefix manipulation, time-based routing, and profit margin protection features let you automatically select the cheapest, highest-quality routes while protecting your margins.

This complete guide is based 100% on the official VOS3000 2.1.9.07 English Manual (pages 217–252). Every menu path, parameter name, table, and example is taken directly from the manual so you get accurate, real-world instructions.

Need professional help setting up advanced LCR, profit control, or full routing optimization on your VOS3000 server? 📲 WhatsApp us immediately at +8801911119966 — our team configures these features daily on live production servers.

How VOS3000 Routing Actually Works (Official Behavior)

VOS3000 uses the longest prefix match rule. When a call arrives, the system first checks the Dial Plan for the most specific prefix before falling back to shorter ones. (Official Manual, Page 219: “When multiple Dial Plans exist, the longest matching pattern will be selected.”), Advanced Routing is important always.

Dial Plan Configuration – Prefix Manipulation (With Real Examples)

The Dial Plan is the foundation of advanced routing. You can add, remove, or replace digits using wildcards and escape characters.

Menu Path: Navigation → Dial Plan (or inside Routing Gateway → Additional Settings)

Original Prefix	Target Prefix	Action	Example Number	Result
0	0	Keep as is	02584316146	02584316146
025	(empty)	Remove prefix	02584316146	84316146
*	12345678	Replace all	02584316146	12345678
0??84	8431	Pattern replace	02584316146	84316146
13/L9	13	Limit length	13812345678	13812345678 (only if 11 digits)

Escape characters explained (Manual Page 219): /L# = shorter than # digits, /E# = exactly # digits, /G# = longer than # digits.

Prefix Routing & Number Transformation – Advanced Routing

In Routing Gateway → Additional Settings → Mapping Prefix you can add prefixes to the callee number and combine with callee dial plan rules.

Example: Add “99” prefix to all international calls for billing identification (SERVER_BILLING_GATEWAY_ROUTE_PREFIX parameter).

Least Cost Routing (LCR) – Full Setup Guide – Advanced Routing

LCR automatically chooses the cheapest gateway by comparing rate per second.

Menu Path: Navigation → Operation Management → Gateway Operation → Routing Gateway

Key parameters you must set:

First Routing Strategy: Lowest Rate per Second (or ASR)
Second Routing Strategy: None / ASR / Lowest Rate per Second
Calculate routing quality in real time: Enable for dynamic ASR/ACD updates

System parameters (Navigation → Softswitch Management → Additional Settings → System Parameter):

SS_GATEWAYFEERATEROUTESORTCONFIG = Before Current Day Total Call
SS_GATEWAYASRROUTESORTCONFIG = Before Current Day Total Call

Profit Margin Protection – How to Stop Losing Money

VOS3000 calculates profit as: Billing Rate (Rate Group) minus Clearing Rate (gateway clearing account).

Key Setting: Lowest Profit Rate Limit (in Routing Gateway)

If profit falls below this value, the gateway is locked automatically. Advanced Routing

Call Type	Billing Rate (per min)	Clearing Rate (per min)	Profit	Action if Lowest Profit Limit = 0.003
BD Mobile	$0.018	$0.014	$0.004	Route allowed
UK Landline	$0.009	$0.0075	$0.0015	Route locked

You can also set Max Minute Rates to block expensive gateways instantly.

Time-Based Routing & Period Control (Peak / Off-Peak)

Perfect for routing cheap routes only during off-peak hours.

Menu Path: Routing Gateway → Additional Settings → Period Control

Four sub-sections:

Period Capacity – set different line limits by time
Period Priority – change gateway priority by time
Period Call Restriction – allow or forbid prefixes by time
Period Dial Plan – rewrite numbers by time of day or weekday

Rate Groups & Clearing Accounts – The Billing Foundation

Rate Groups define how you bill your customers. Clearing Accounts define what you pay your suppliers.

Menu Path for Rate Groups: Navigation → Rate Management → Rate Group Management

Inside Rate Management you set:

Billing rate
Billing cycle (seconds)
Section rate (first duration + subsequent)
Tax rate

ASR / ACD Real-Time Filters & Dynamic Switching Advanced Routing

Enable “Calculate routing quality in real time” so the system automatically switches to backup routes when ASR or ACD drops.

Monitor everything in Business Analysis → Routing Analysis.

❓ Frequently Asked Questions (FAQ)

Q1: What is the default routing method in VOS3000?

Longest prefix match + gateway sorting strategies (Manual Page 219).
Q2: How does profit control actually work?

It compares your billing rate (Rate Group) with the gateway clearing rate and locks the route if profit is below Lowest Profit Rate Limit.
Q3: Can I route calls differently during peak hours?

Yes — use Period Control (4 sub-sections) to set different priorities, limits, and dial plans by time of day.
Q4: Where do I set Lowest Profit Rate Limit?

In Routing Gateway → edit gateway → Lowest Profit Rate Limit field.
Q5: How to enable real-time ASR sorting?

Enable “Calculate routing quality in real time” and set SS_GATEWAYASRROUTESORTCONFIG in System Parameters.
