⚙️ Billing Calculation Example (VOS3000 Account Billing)

Billing Calculation Example:
===========================

Rate Configuration:
- First Time Rate: 0.21
- First Time Duration: 180 seconds
- Billing Rate: 0.15
- Billing Cycle: 60 seconds
- Tax Rate: 10%

Call Duration: 250 seconds

Calculation:
Step 1: First time rate applies for first 180 seconds
        Charge = 0.21

Step 2: Remaining duration = 250 - 180 = 70 seconds
        This falls into 2 billing cycles (60s each, rounded up)
        Charge = 0.15 × 2 = 0.30

Step 3: Total base charge = 0.21 + 0.30 = 0.51

Step 4: Tax = 0.51 × 10% = 0.051

Total Charge to Account = 0.51 + 0.051 = 0.561

Note: CDR shows base rate; reports show base + tax

📊 Longest Matching Prefix Principle (VOS3000 Account Billing)

🚨 Common Billing Issues & Solutions

📋 Billing Troubleshooting

Problem	Possible Cause	Solution
Calls not being billed	No matching rate prefix	Add rate for called number prefix
Wrong rate applied	Multiple prefixes match	Review longest matching prefix
Account shows wrong balance	Package charge or minimum consumption	Check package and minimum consumption settings
Rate type authorization failure	Account lacks permission	Update account authorization type
Tax not showing in CDR	Normal behavior	CDR shows base rate; reports show tax inclusive

❓ Frequently Asked Questions

How does VOS3000 select which rate to use for billing?

VOS3000 uses the longest matching prefix principle. When a call is made, the system looks for the rate prefix that matches the most digits of the called number. If multiple rates exist (account rate, phone private rate, package rate), the system selects the lowest cost option.

What is the difference between First Time Rate and Billing Rate?

First Time Rate is charged for the initial billing period (First Time Duration). After that period, Billing Rate is charged for each subsequent Billing Cycle. This allows for different pricing for the first minute versus subsequent minutes of a call.

How do packages affect billing?

Packages can provide free minutes, free credit, or discounted rates (period rates). When a package is active on an account, the system checks if the call qualifies for package benefits before applying standard rates. Free duration is consumed first, then package rates apply.

Can I have different rates for the same destination for different accounts?

Yes. Assign different rate groups to different accounts, or use private rate groups for specific accounts. Each account can have its own pricing structure through rate group assignment.

What happens if a called number doesn’t match any rate?

If no rate prefix matches the called number, the call will be terminated with “No Matching Rate” as the termination reason. Always ensure rate coverage for all destinations your customers may call.

❓ Frequently Asked Questions

What happens when I make a payment to an account?

When you perform a Payment operation, the specified amount is added to the account’s current balance. The payment is recorded in the payment records table with timestamp, operator ID, and any memo notes. If the SERVER_PAY_DELAY_CUSTOMER_EXPIRE_DAY parameter is configured, the account expiration date will also be extended.

What is the difference between Payment and Credit?

Payment adds funds directly to the account balance, increasing the available credit. Credit sets the overdraft limit, which allows the account to go negative up to that limit. Use Payment for normal recharges; use Credit to allow postpaid-style calling beyond current balance.

How do I track all payments made by an agent?

Navigate to Data query > Payment record and filter by the operator name. All payments made by that agent user will be displayed. You can export this report for accounting purposes.

Can payments be reversed or deleted?

Payment records cannot be directly deleted from the transaction history for audit purposes. To correct an erroneous payment, perform a negative adjustment (make a payment with negative impact by adjusting balance) or use the Make Zero function to reset balance, then add the correct amount.

How does the minimum consumption work with payments?

Minimum consumption (Monthly Min) ensures a minimum revenue per account. At the beginning of each month (configured time), if the account’s consumption for the previous month was below the minimum, the difference is charged from the account balance. Ensure accounts have adequate balance to cover minimum consumption charges.

❓ Frequently Asked Questions

What is the difference between static and registration gateway types?

Static gateways use a fixed IP address configured in VOS3000, and no SIP REGISTER is required. Registration gateways send SIP REGISTER messages to VOS3000 with credentials, supporting dynamic IP addresses and NAT traversal. Static is best for dedicated hardware with fixed IPs, while registration suits remote gateways and devices behind NAT.

How do I enable debug tracing for registration issues?

Navigate to Online routing gateway or Online mapping gateway, right-click the specific gateway, and select “Register tracing” to enable. This captures SIP registration messages without affecting the system-wide debug trace settings. You can set duration for the trace capture period.

What authentication method should I use for vendor SIP trunks?

For vendor SIP trunks over public internet, use Password Authentication Required for highest security. This requires the gateway to authenticate with username/password via SIP digest authentication. For trusted private networks, IP authentication may be sufficient.

Why does my gateway keep losing registration?

Common causes include NAT binding timeouts, firewall blocking keepalive messages, or registration expiry being too short. Configure NAT keepalive settings (SS_SIP_NAT_KEEP_ALIVE_PERIOD), ensure firewall allows SIP traffic, and verify registration expiry times match between gateway and VOS3000.

Can multiple devices register with the same gateway ID?

Yes, but each registration will update the registered IP address. The last registration received will be the active one. For load balancing or failover, consider using multiple gateway configurations with different Device IDs.

📊 ASR-Based Routing Configuration

Reference: VOS3000 2.1.9.07 Manual, Section 4.3.5.2 (Page 235-236)

⚙️ ASR Routing Parameters (VOS3000 Routing Optimization)

Parameter	Default	Range	Description
SS_GATEWAY_ASR_CALCULATE	Off	On/Off	Enable real-time ASR calculation
SS_GATEWAY_ASR_RESERVE_TIME	600	300-86400 sec	Time window for ASR calculation
SS_GATEWAY_ASR_RESERVE_SEPARATE	10	5-24	Number of time segments for ASR calculation
SS_GATEWAYASRROUTESORTCONFIG	Before line usage	Position options	Where ASR sorting is inserted in algorithm

📐 How ASR is Calculated

Reference: VOS3000 2.1.9.07 Manual, Section 4.1.1 (Page 212)

VOS3000 ASR Calculation Method:
===============================

Formula: ASR = (Answered Calls / Total Call Attempts) × 100%

VOS3000 divides ASR calculation into time segments:
- Segment length = SS_GATEWAY_ASR_RESERVE_TIME / SS_GATEWAY_ASR_RESERVE_SEPARATE
- Example: 600 / 10 = 60 seconds per segment
- ASR at any point = mean of last 10 segments (rolling average)

Example Calculation:
===================
SS_GATEWAY_ASR_RESERVE_TIME = 600 (10 minutes)
SS_GATEWAY_ASR_RESERVE_SEPARATE = 10 segments

Time segments (each 60 seconds):
Segment 1: 0-60 sec    → 45 attempts, 25 answered = 55.6% ASR
Segment 2: 60-120 sec  → 50 attempts, 30 answered = 60.0% ASR
Segment 3: 120-180 sec → 40 attempts, 22 answered = 55.0% ASR

🔧 Enabling ASR-Based Routing

Step-by-Step ASR Routing Configuration:
=======================================

1. Enable Real-Time ASR Calculation:
   Location: Softswitch management > Additional settings > System parameter
   Parameter: SS_GATEWAY_ASR_CALCULATE
   Set to: On

2. Configure ASR Time Window:
   Parameter: SS_GATEWAY_ASR_RESERVE_TIME
   Recommended: 600 (10 minutes) for responsive routing
   Higher values = more stable but slower to react

3. Set Calculation Segments:
   Parameter: SS_GATEWAY_ASR_RESERVE_SEPARATE
   Recommended: 10 segments
   Each segment = 60 seconds in this example

4. Set ASR Sorting Position:
   Parameter: SS_GATEWAYASRROUTESORTCONFIG
   Options:
   - "Before line usage" (default)
   - "Before gateway ID"

5. Enable ASR Routing on Gateway:
   Location: Routing Gateway > Additional settings
   Check: "Calculate routing quality in real time"

6. Apply and Test:
   - Make test calls
   - Monitor CDR for gateway selection
   - Verify ASR-based routing is active

📊 ACD-Based Routing Configuration

Reference: VOS3000 2.1.9.07 Manual, Section 4.3.5.2 (Page 235-236)

⚙️ ACD Routing Parameters (VOS3000 Routing Optimization)

Parameter	Default	Range	Description
SS_GATEWAY_ACD_CALCULATE	Off	On/Off	Enable real-time ACD calculation
SS_GATEWAY_ACD_RESERVE_TIME	600	300-86400 sec	Time window for ACD calculation
SS_GATEWAY_ACD_RESERVE_SEPARATE	10	5-24	Number of time segments for ACD calculation

📐 ACD Calculation Method

VOS3000 ACD Calculation:
========================

Formula: ACD = Total Duration of Answered Calls / Number of Answered Calls

Example:
- 30 answered calls in time window
- Total duration: 4500 seconds
- ACD = 4500 / 30 = 150 seconds (2.5 minutes)

ACD indicates call quality:
- High ACD (> 180 sec): Good voice quality, engaged conversations
- Medium ACD (60-180 sec): Normal for most destinations
- Low ACD (< 60 sec): Possible quality issues, quick hangups

Use Cases for ACD Routing:
==========================
1. Route to gateways with longer average call duration
2. Avoid gateways where calls drop quickly
3. Balance quality with cost considerations
4. Detect and avoid fraud routes (unusually high ACD)

💰 Rate-Based Routing Configuration

Reference: VOS3000 2.1.9.07 Manual, Section 4.3.3 (Page 220-221)

⚙️ Rate Routing Parameters

Parameter	Default	Description
SS_GATEWAYFEERATEROUTESORTCONFIG	Before line usage	Position for rate-based sorting in algorithm
SS_GATEWAY_FEE_RATE_ROUTE_BEFORE_ASR	Off	Rate routing priority over ASR routing

⚖️ Balancing Cost vs Quality (VOS3000 Routing Optimization)

The key decision in routing optimization is balancing cost (rate) against quality (ASR/ACD). VOS3000 provides multiple strategies:

Strategy	Configuration	Best For	Trade-off
Lowest Cost First	Rate routing before ASR, ASR disabled	Wholesale, high margin routes	May have quality issues
Best Quality First	ASR routing before rate, rate disabled	Premium services, retail	Higher cost per minute
Balanced Approach	Both enabled, rate before ASR	General wholesale operations	Moderate cost, moderate quality
Quality with Cost Fallback	ASR before rate, rate as secondary	Premium with cost management	Quality prioritized when available

🔄 Gateway Switch Configuration

Reference: VOS3000 2.1.9.07 Manual, Section 4.3.5.2 (Page 236)

⚙️ Gateway Switch Parameters

Parameter	Default	Description
SS_GATEWAY_SWITCH_LIMIT	None	Maximum auto-switch attempts before stopping
SS_GATEWAY_SWITCH_STOP_AFTER_RTP_START	On	Stop switching after RTP media starts
SS_GATEWAY_SWITCH_STOP_AFTER_USER_BUSY	On	Stop switching when user is busy
SS_GATEWAY_SWITCH_UNTIL_CONNECT	Off	Keep switching until call connects

📐 Gateway Switch Behavior (VOS3000 Routing Optimization)

How Gateway Switching Works:
============================

When a call fails on one gateway, VOS3000 can automatically try the next available gateway.

Example with SS_GATEWAY_SWITCH_LIMIT = 3:
=========================================
Call attempt 1: Gateway A (fails)
Call attempt 2: Gateway B (fails)
Call attempt 3: Gateway C (fails)
→ Stop trying, return failure to caller

Example with SS_GATEWAY_SWITCH_LIMIT = None:
============================================
Call attempt 1: Gateway A (fails)
Call attempt 2: Gateway B (fails)
Call attempt 3: Gateway C (connects)
→ Success!

Configuration Recommendations:
=============================
- High-value routes: SS_GATEWAY_SWITCH_LIMIT = None (unlimited retries)
- Standard routes: SS_GATEWAY_SWITCH_LIMIT = 3-5
- Capacity-limited: SS_GATEWAY_SWITCH_LIMIT = 2-3

Stop Conditions:
================
- RTP Started: Stop after media established (prevents disruption)
- User Busy: Don't retry on busy destination
- Until Connect: Keep trying until connected or all gateways exhausted

📊 Quality Reserve Time System

Reference: VOS3000 2.1.9.07 Manual, Section 4.1.1 (Page 212)

The quality reserve time system controls how VOS3000 calculates and uses quality metrics for routing decisions.

⚙️ Quality Reserve Parameters (VOS3000 Routing Optimization)

Parameter	Default	Purpose
SS_GATEWAY_QUALITY_RESERVE_TIME	600	Total time window for quality calculation (seconds)
SS_GATEWAY_QUALITY_RESERVE_SEPARATE	10	Number of segments to divide the time window

📐 Quality Calculation Example

Quality Reserve Time Calculation:
=================================

Given:
- SS_GATEWAY_QUALITY_RESERVE_TIME = 600 seconds (10 minutes)
- SS_GATEWAY_QUALITY_RESERVE_SEPARATE = 10 segments

Each segment = 600 / 10 = 60 seconds

Gateway ASR over 10 minutes:
Segment 1 (0-60s):    55% ASR
Segment 2 (60-120s):  58% ASR
Segment 3 (120-180s): 52% ASR
Segment 4 (180-240s): 60% ASR
Segment 5 (240-300s): 57% ASR
Segment 6 (300-360s): 54% ASR
Segment 7 (360-420s): 59% ASR
Segment 8 (420-480s): 56% ASR
Segment 9 (480-540s): 61% ASR
Segment 10 (540-600s): 58% ASR

Current Gateway ASR = Average of all 10 segments = 57%

This rolling average provides:
- Smooth response to quality changes
- Protection from temporary spikes
- Historical context for decisions

❓ Frequently Asked Questions

What is a good ASR value for VoIP routes?

ASR values vary significantly by destination type. International routes typically see 30-50% ASR, while domestic routes may achieve 50-70%. Premium routes can reach 70%+. Compare your ASR against industry benchmarks for similar destinations rather than absolute values.

Should I use ASR or rate-based routing?

It depends on your business model. For wholesale operations with thin margins, rate-based routing may be appropriate. For retail or premium services where customer satisfaction is critical, ASR-based routing ensures better quality. Many operators use a balanced approach with rate routing as primary and ASR as quality threshold.

How often does VOS3000 update ASR calculations?

VOS3000 calculates ASR continuously in real-time when SS_GATEWAY_ASR_CALCULATE is enabled. The quality reserve time parameters determine the time window and granularity. With default settings (600 seconds, 10 segments), each 60-second period contributes to the rolling average.

Can gateway switching cause duplicate calls?

No, VOS3000 handles gateway switching at the signaling level. When a call fails on one gateway, the system tries the next gateway before responding to the caller. The caller sees only one call attempt, even if VOS3000 tried multiple gateways internally.

How do I monitor route quality in VOS3000?

Use the Gateway Performance reports in VOS3000: Navigation > Data query > CDR Analysis > Historical Performance. This shows ASR, ACD, and call volume trends. You can also enable gateway analysis reports in system parameters.

📞 Need help with VOS3000 dial plan? WhatsApp: +8801911119966

🔍 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)

0134	$$$	0134131	013131	$ keeps original digit position

🔀 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

🚨 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.

VOS3000 High Availability and Load Balancing Setup Easy Guide

March 10, 2026March 10, 2026 king

Easy Guide to VOS3000 High Availability and Load Balancing Setup

VOS3000 High availability represents a critical requirement for telecommunications service providers who must maintain continuous operation to meet customer expectations and contractual service level agreements. The VOS3000 softswitch platform provides comprehensive high availability capabilities through master-slave server architecture, automatic failover mechanisms, and sophisticated load balancing features that distribute traffic across multiple processing nodes.

Understanding how to properly configure and maintain these capabilities is essential for building resilient VoIP networks that can withstand hardware failures, software issues, and unexpected traffic spikes without service interruption. VOS3000 High Availability

📌 Understanding High Availability Architecture

The VOS3000 high availability architecture operates on a primary-backup model where a master server handles active call processing while one or more slave servers maintain synchronized copies of configuration and runtime data. The synchronization process continuously replicates database changes, registration information, and operational state from the master to slave nodes. VOS3000 High Availability

For disaster recovery planning, see our comprehensive guide on VOS3000 Disaster Recovery.

🔧 Master-Slave Server Configuration

The master-slave configuration in VOS3000 establishes the foundation for high availability operation:

🔹 Master Server Role

Handles all active call processing and routing decisions
Maintains the primary database with all write operations
Processes all signaling traffic from endpoints
Serves as the primary client connection point

🔹 Slave Server Role

Operates in standby mode, ready for failover
Continuously receives synchronized data from master
Monitors master health through heartbeat mechanisms
Maintains complete copy of all configuration and billing data

🔹 Server Requirements Matrix

Requirement	Master Server	Slave Server
VOS3000 Version	2.1.8.05 / 2.1.9.07	Same version as master
Operating System	CentOS 6/7	CentOS 6/7
Network	Static IP, low latency	Same network preferred
License	HA-enabled license	HA-enabled license

🔄 Failover Mechanisms and Detection

VOS3000 implements multiple detection mechanisms that identify when failover is necessary. The clock deviation alarm monitors the time synchronization between master and slave servers, detecting situations where server clocks drift apart. Accurate time synchronization is critical for proper database replication.

The master synchronize status alarm triggers when host synchronization stops working, indicating potential problems with the master server that may require failover. Similarly, the slave synchronize status alarm monitors the health of backup servers. VOS3000 High Availability

For backup procedures, see our guide on How to Backup Restore VOS3000 MySQL Database.

📊 Gateway Group Load Balancing

Beyond server-level redundancy, VOS3000 provides gateway group capabilities that enable load balancing and redundancy at the termination layer. Gateway groups organize multiple routing gateways into logical collections with defined capacity limits, enabling intelligent distribution of call traffic across multiple termination points.

The line limit parameter at the gateway group level establishes the maximum concurrent calls that can be processed through all gateways in the group collectively. Individual gateway line limits work in conjunction with group limits, ensuring that no single gateway can consume all available group capacity.

🔹 Load Balancing Configuration Example

Gateway Group	Total Line Limit	Gateway A Limit	Gateway B Limit
Group_Premium	600	400 (Priority 1)	200 (Priority 2)
Group_Standard	300	150 (Priority 1)	150 (Priority 1)

For multiple IP configurations, see our guide on Multiple IP License in VOS3000.

🎯 Priority-Based Traffic Distribution

Priority settings on routing gateways provide the primary mechanism for controlling traffic distribution in load balancing scenarios. When multiple gateways are available for a destination, those with lower priority numbers receive traffic first, implementing a preferred routing hierarchy.

VOS3000 enhances this basic priority model with additional factors that influence gateway selection. The ratio of current calls to maximum channels is considered when multiple gateways share the same priority, naturally distributing load across equally-preferred termination points based on available capacity. VOS3000 High Availability

📈 Period Capacity Management

VOS3000 period capacity features enable time-based load balancing configurations that adapt to predictable traffic patterns. The period capacity settings allow gateway line limits to vary based on time of day and day of week, enabling higher capacity during peak traffic hours and reduced capacity during low-traffic periods.

✅ Peak Hours (9AM-6PM): Higher capacity allocations
✅ Off-Peak Hours (6PM-9AM): Reduced capacity, cost-optimized
✅ Weekends: Special routing configurations

For server rental options across different regions, see VOS3000 Rental Server.

⚙️ System Monitoring for VOS3000 High Availability

Comprehensive monitoring is essential for maintaining high availability, and VOS3000 provides extensive alarm capabilities that detect conditions requiring attention:

Alarm Type	Trigger	Severity
CPU Alarm	CPU usage exceeds threshold	Major/Critical
Memory Alarm	Memory usage exceeds threshold	Major
Database Alarm	Database errors detected	Critical
Pending CDR Alarm	CDR processing backlog	Major
Clock Deviation	Time sync issues between servers	Major

💡 Best Practices Summary – VOS3000 High Availability

✅ Ensure accurate NTP time synchronization across all servers
✅ Configure all relevant alarms with email notifications
✅ Regularly test failover procedures (monthly recommended)
✅ Monitor performance metrics continuously
✅ Maintain current backups of all configuration data
✅ Document all HA configurations and procedures
✅ Use dedicated network links for replication traffic

🔧 Maintenance Procedures

When performing maintenance on the master server, proper failover procedures ensure that slave servers assume processing duties without service interruption. The Master Server Lock function in VOS3000 enables controlled failover by preventing a server from assuming master status.

Regular testing of failover capabilities is essential for validating that high availability configurations function correctly when needed. Schedule periodic failover tests that verify slave servers can successfully assume master duties.

For dynamic gateways, the gateway name serves as the unique identifier used for authentication, while the configuration password provides secure credential verification during the registration process. Static gateways should be restricted to specific IP addresses for additional security. VoIP Fraud Prevention

🔐 Password Security and User Management

VOS3000 implements comprehensive password security policies that align with industry best practices for preventing unauthorized access. Password requirements mandate a minimum of six characters for standard users and eight characters for administrator accounts, with complexity requirements specifying at least two of the following: lowercase letters, uppercase letters, numbers, or special characters.

The dynamic password feature provides an additional security layer through time-based one-time password (TOTP) technology. Users can enable this feature for their accounts, which then requires a continuously changing password generated by a mobile authenticator application. The VOS3000 OTP application generates authentication codes that change every 30 seconds.

⚠️ Alarm System for Fraud Detection – VoIP Fraud Prevention

VOS3000 includes a sophisticated alarm management system that provides real-time detection of suspicious activities that may indicate fraudulent behavior. The system alarm configuration includes specific alarm types designed to identify potential fraud:

Account call duration too long: Triggers when call durations exceed configured thresholds
Illegal call: Monitors for calls that violate configured restrictions
Balance alarm: Alerts when balances fall below thresholds
Unusual traffic patterns: Detects spikes in call volume

For comprehensive alarm setup, see our VOS3000 Monitoring Alarms Statistics guide.

📊 Balance Monitoring and Financial Controls

Balance alarm capabilities in VOS3000 provide essential financial controls that help prevent fraud-related losses from accumulating unnoticed. The system can monitor account balances and generate alerts when balances fall below configured thresholds, enabling operators to identify accounts that may have been compromised.

The anti-overdraft feature, when enabled, prevents calls from exceeding preset amounts by calculating advance amounts for ongoing calls. This real-time credit management capability ensures that accounts cannot continue to incur charges beyond their available balance plus authorized overdraft, creating a hard stop that limits potential fraud losses. VoIP Fraud Prevention

🎯 Gateway-Level Security Controls

Individual gateway configurations in VOS3000 include multiple security parameters that contribute to overall fraud prevention. The caller and callee prefix controls allow operators to specify exactly which number patterns are permitted or prohibited from passing through each gateway.

These controls operate independently for caller and called numbers, enabling granular restrictions such as allowing domestic calls while blocking high-cost international destinations that are commonly targeted in toll fraud schemes.

For advanced security measures, refer to our VOS3000 Anti Hack guide.

🔍 Black and White List Management

VOS3000 provides comprehensive black and white list management capabilities that enable operators to implement explicit allow and deny policies for specific numbers or number patterns. The Black/White List Group feature allows creation of named groups containing specific number patterns that can then be applied to gateway configurations.

List Type	Function	Use Case
White List	Allow only specified numbers	Restrict to approved destinations
Black List	Block specified numbers	Block known fraud sources
Dynamic Black List	Auto-block suspicious numbers	Real-time fraud protection

📡 SIP Security Configuration Options

The SIP protocol configuration options in VOS3000 include several parameters that enhance security for SIP-based connections. The Reply address setting controls how the system responds to SIP requests, with three options: Socket (recommended), Via port, and Via. The recommended Socket option ensures that responses are sent to the actual source of the request.

Privacy header settings support SIP privacy mechanisms that help protect caller identity information. These protocol-level security settings should be configured in conjunction with network security measures to create a comprehensive security framework.

🚨 DDoS Protection and Rate Limiting

VOS3000 provides protection against denial of service attacks through configurable rate limiting parameters. Calls per second (CPS) limits can be set per gateway to prevent any single source from overwhelming system resources. These limits also help contain the impact of compromised credentials by restricting the maximum rate of fraudulent calls.

For DDoS protection strategies, see our detailed guide on DDoS Attack in VOS3000 Servers.
