VOS3000 P-Asserted-Identity: Caller ID Manipulation Guide for VoIP

Configuring VOS3000 P-Asserted-Identity correctly is crucial for VoIP operators who need to control how caller ID information is presented to termination providers, regulatory bodies, and end users. The P-Asserted-Identity (PAI) header, defined in RFC 3325, is the industry-standard mechanism for asserting the identity of the calling party within trusted VoIP networks. Many termination vendors require specific PAI header configuration to accept calls, and incorrect PAI settings result in calls being rejected, caller ID not displaying correctly, or compliance violations that can jeopardize your entire operation. VOS3000 P-Asserted-Identity

This guide provides a complete walkthrough of VOS3000 P-Asserted-Identity configuration, including the related Privacy and P-Preferred-Identity headers, caller dial plans, and advanced caller ID manipulation techniques. All configuration details reference the official VOS3000 V2.1.9.07 Manual. For professional assistance, contact us on WhatsApp at +8801911119966.

Understanding VOS3000 P-Asserted-Identity Header

The P-Asserted-Identity header serves a specific purpose in SIP signaling that is fundamentally different from the standard From header. While the From header identifies the caller as claimed by the caller’s device, the PAI header asserts the caller’s identity as verified by a trusted network element — in this case, your VOS3000 softswitch. This distinction is critical because termination providers rely on the PAI header to determine the actual calling party for billing, routing, and regulatory compliance purposes.

Why P-Asserted-Identity Matters for VoIP Operators

In the VOS3000 ecosystem, the PAI header impacts several critical aspects of your VoIP business. Termination vendors increasingly require PAI headers to process calls correctly, especially for emergency services and regulatory compliance. Without proper PAI configuration, your calls may be rejected by vendors or flagged as suspicious. Additionally, the PAI header determines how your customers’ caller ID appears to the called party, which affects your customers’ business credibility and call completion rates.

Key reasons to configure VOS3000 P-Asserted-Identity correctly:

  • Vendor requirements: Many termination providers require PAI headers to accept calls and bill correctly
  • Regulatory compliance: Telecom regulations in many jurisdictions require accurate caller ID presentation
  • Call completion: Proper PAI configuration prevents calls from being blocked by downstream providers
  • Emergency services: Emergency call routing depends on accurate PAI for location identification
  • Anti-spoofing: PAI with Privacy headers provides controlled caller ID presentation that prevents spoofing accusations

Configuring VOS3000 P-Asserted-Identity on Routing Gateway

The PAI configuration for routing gateways is located in the Additional Settings > Protocol > SIP section. Navigate to Operation Management > Gateway Operation > Routing Gateway, double-click a gateway, and access the Protocol > SIP settings (VOS3000 Manual Section 2.5.1.1, Page 43). These settings control how VOS3000 handles caller identity information when sending calls to your termination vendors.

P-Asserted-Identity Settings

VOS3000 provides three options for the PAI header on routing gateways, as documented in VOS3000 Manual Section 2.5.1.1 (Page 43):

  • None: The PAI header is not included in outgoing SIP messages to this gateway. Use this when the vendor does not require or expect a PAI header
  • Pass through: VOS3000 forwards the PAI header exactly as received from the mapping gateway (caller side). This preserves the original PAI value without modification, which is useful when the upstream device has already set the correct PAI
  • Caller: VOS3000 generates a new PAI header using the caller’s number. This is the most common setting because it ensures the PAI contains the correct caller ID regardless of what the caller’s device sent

For most deployments, the “Caller” option is recommended because it guarantees that the PAI header contains the actual calling number from VOS3000’s perspective. The “Pass through” option should only be used when you trust the upstream device to provide accurate PAI values. VOS3000 P-Asserted-Identity

Privacy Header Configuration

The Privacy header works in conjunction with the PAI header to control whether the caller’s identity should be hidden from the called party. According to the VOS3000 Manual (Page 43), there are three Privacy options:

  • None: No Privacy header is included in outgoing messages. The caller ID is presented normally
  • Passthrough: VOS3000 forwards the Privacy header as received from the mapping gateway. If the caller requested privacy, that request is preserved
  • Id: VOS3000 adds a Privacy: id header, which requests that the called party’s network hide the caller’s identity from display

The Privacy header is particularly important for regulatory compliance. In many jurisdictions, callers have the right to withhold their caller ID, and the Privacy: id header signals this request to downstream networks. When a call with Privacy: id is received, the called party’s network should suppress the caller ID display while still using the PAI header internally for billing and emergency services.

⚙️ Setting🟢 Recommended📝 When to Use Other Options
P-Asserted-IdentityCallerPass through: upstream PAI trusted; None: vendor doesn’t use PAI
PrivacyPassthroughNone: never hide caller ID; Id: always hide caller ID
P-Preferred-IdentityNonePassthrough: preserve upstream PPI; Caller: set from caller number
Caller dial planAs neededWhen vendor requires specific number format in PAI

P-Preferred-Identity Configuration

The P-Preferred-Identity (PPI) header is similar to PAI but is used in a different context. While PAI is used by networks to assert identity, PPI is used by user agents (phones, PBXs) to indicate their preferred identity. In VOS3000, the PPI options (VOS3000 Manual, Page 43) are identical to PAI:

  • None: No PPI header is included
  • Passthrough: Forward the PPI header as received from the mapping gateway
  • Caller: Generate a new PPI header using the caller’s number

In most VOS3000 deployments, the PPI header is set to “None” because the PAI header is the primary mechanism for identity assertion at the softswitch level. PPI is more relevant for user-agent-to-proxy communication, while PAI is for proxy-to-proxy communication. However, some vendors may require specific PPI configuration, so understanding this option is important.

VOS3000 P-Asserted-Identity Caller Dial Plan

The “Caller dial plan” setting associated with the PAI configuration allows you to transform the caller number before it is inserted into the PAI header. This is essential when your vendor requires a specific number format in the PAI header that differs from how numbers are stored in VOS3000.

Common Caller Number Transformation Scenarios

Different vendors expect different number formats in the PAI header. Here are the most common scenarios that require caller dial plan configuration:

  • Country code addition: Your internal numbers may not include the country code, but the vendor requires it. A dial plan can prepend the country code (e.g., +880) to the caller number in the PAI header
  • Leading zero removal: Some vendors require numbers without leading zeros. A dial plan can strip leading zeros from the caller number
  • Number format conversion: Converting between E.164 format and national format as required by the vendor
  • Prefix addition: Adding a specific prefix that the vendor uses to identify your traffic
🔄 Transformation📝 Original Number✅ PAI Number🎯 Reason

Advanced VOS3000 P-Asserted-Identity Features

Beyond the basic PAI, Privacy, and PPI settings, VOS3000 provides several advanced features that give you more control over caller identity handling.

Allow All Extra Header Fields

The “Allow all extra header fields” option (VOS3000 Manual, Page 43) enables SIP header transparency, allowing all additional header domains from the incoming SIP message to pass through to the routing gateway. When enabled, any custom or non-standard SIP headers received from the mapping gateway are forwarded unchanged. This is useful when your upstream provider sends proprietary headers that your downstream vendor expects to receive.

Allow Specified Extra Header Fields

For more granular control, the “Allow specified extra header fields” option lets you define exactly which additional header fields should be forwarded. This provides better security than allowing all headers because you can restrict passthrough to only the headers your vendor requires. Add specific header field names to the list, and only those headers will be forwarded from the incoming SIP message to the outgoing message.

Peer Number Information

The “Peer number information” setting controls which field VOS3000 uses to extract the caller number from incoming SIP signals. Available options include extracting from the From header, Display field, or Remote-Party-ID header. This setting determines the source of the caller number that may be used in the PAI header when set to “Caller” mode.

Caller Number Pool for PAI

When you need to substitute the caller ID with numbers from a pool rather than using the actual caller number, VOS3000 provides the “Enable caller number pool” feature in the routing gateway additional settings (VOS3000 Manual Section 2.5.1.1, Page 51). This feature replaces the original caller number with a number from a configured pool, which then appears in both the From header and PAI header. The number sequence can be random (0) or poll (1), configured by the FORWARD_SIGNAL_REWRITE_SEQUENCE setting in softswitch.conf. The “Multiplexes” field controls how many times each pool number can be reused concurrently.

Configuring VOS3000 P-Asserted-Identity on Mapping Gateway

The mapping gateway (customer-side) also has caller identity configuration options in the Additional Settings > Protocol > SIP section (VOS3000 Manual Section 2.5.1.2, Page 57). The mapping gateway settings control how VOS3000 handles caller identity from your customers’ devices.

Mapping Gateway Caller Settings

On the mapping gateway, the key caller identity settings include:

  • Caller: Determines which field of the SIP signal to extract the caller number from. Options include “From” (from the From header), “Remote-Party-ID” (from the RPID header), and “Display” (from the Display field)
  • Support Privacy: Enables passthrough of the mapping gateway’s privacy domain settings
  • Recognize call forward signal: Identifies forwarding-formatted calls for proper handling

The mapping gateway’s caller extraction method determines the initial caller number that VOS3000 uses internally. This number then flows to the routing gateway where the PAI configuration determines how it is presented to the vendor. If the mapping gateway extracts the wrong caller number, the PAI header on the routing gateway will also be wrong.

Troubleshooting VOS3000 P-Asserted-Identity Issues

PAI configuration problems can be difficult to diagnose because the SIP headers are not visible in the VOS3000 client interface. Here are the most common issues and how to resolve them.

Issue 1: Vendor Rejects Calls Due to Missing PAI

If your vendor requires the PAI header but you have it set to “None” on the routing gateway, calls will be rejected. The fix is straightforward: change the PAI setting to “Caller” so VOS3000 generates the PAI header with the caller’s number. Some vendors may also require the number in a specific format, which you can achieve with the Caller dial plan setting.

Issue 2: Wrong Number in PAI Header

If the PAI header contains an incorrect number, check the chain of caller number extraction. Start with the mapping gateway’s Caller setting to verify the correct source field is being used. Then check if any dial plans on the mapping gateway are transforming the number before it reaches the routing gateway. Finally, verify the Caller dial plan on the routing gateway’s PAI configuration is applying the correct transformation.

Issue 3: Caller ID Displayed When Privacy Is Requested

If a caller requests privacy but their number is still displayed to the called party, check that the Privacy setting on the routing gateway is not set to “None”. It should be “Passthrough” to honor the caller’s privacy request, or “Id” to always add the privacy header. Also verify that the mapping gateway’s “Support Privacy” option is enabled so that privacy requests from the caller’s device are forwarded.

Standard SIP trunkCallerPassthroughMost common configuration
Legacy H323 gatewayNoneNoneH323 does not use PAI
Emergency servicesCallerNoneMust always show caller ID
Privacy-required routeCallerIdAlways hide caller ID display

Testing PAI Configuration

After configuring VOS3000 P-Asserted-Identity, test with actual calls to verify the headers are being set correctly. Use a SIP phone or softphone to place a test call and examine the SIP messages at the vendor’s side. Verify that the PAI header contains the correct number in the expected format, and that the Privacy header is present when required. For detailed call testing instructions, see our VOS3000 call test and troubleshooting guide.

Frequently Asked Questions About VOS3000 P-Asserted-Identity

❓ What is the difference between PAI and P-Preferred-Identity in VOS3000?

P-Asserted-Identity (PAI) is used by network servers (like VOS3000) to assert the identity of the calling party to other trusted network elements. P-Preferred-Identity (PPI) is used by user agents (like SIP phones) to indicate their preferred identity to the network. In VOS3000, PAI is the primary header for caller ID presentation to vendors, while PPI is rarely needed and is typically set to “None” in most deployments.

❓ Should I set PAI to “Passthrough” or “Caller”?

Use “Caller” in most cases because it ensures VOS3000 generates the PAI header from the verified caller number in its database. Use “Passthrough” only when you fully trust the upstream device to provide accurate PAI values and you want to preserve them unchanged. The risk with “Passthrough” is that incorrect or spoofed PAI values from the upstream could be forwarded to your vendor.

❓ Why does my vendor require a specific number format in the PAI header?

Vendors use the PAI header for billing, routing, and regulatory compliance. They need the number in a consistent format (usually E.164 with country code and plus sign) to correctly identify the calling party and apply the appropriate rates. Use the Caller dial plan on the routing gateway to transform the number into the format your vendor requires.

❓ How do I hide caller ID using VOS3000 P-Asserted-Identity?

Set the Privacy option to “Id” on the routing gateway to add a Privacy: id header to all outgoing calls. This signals to the called party’s network that the caller’s identity should be hidden from display. Note that the PAI header is still included (for billing and emergency purposes), but the called party’s device should not show the caller ID to the end user.

❓ Can I set different PAI configurations for different vendors?

Yes, each routing gateway in VOS3000 has its own independent PAI configuration. This means you can configure one vendor with PAI set to “Caller” and a specific dial plan, while another vendor uses “Passthrough” or “None”. This flexibility is essential when working with multiple vendors that have different caller ID requirements.

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.

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 GatewayVendor gateway settingsCaller prefix, caller rewrite
2.5.1.2 Mapping GatewayCustomer gateway settingsCaller rewrite rules
2.5.2 Phone ManagementPhone/extension settingsDisplay caller ID
4.3.5 Softswitch ParametersSystem-wide settingsCaller 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
BlankAllow all lengthsNo restriction
11Only 11-digit numbersUS/Canada mobile format
10, 1110 or 11-digit numbersUS numbers with/without 1
0Block all numbersEmergency 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
AllowOnly specified prefixes passAllow 1,44,86 – only US, UK, China callers
ForbiddenSpecified prefixes blockedForbidden 88 – block Bangladesh prefix
Allow (blank)All prefixes passNo 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 PrefixPrepend digits to caller IDAdd 1 to US numbers
Remove PrefixStrip leading digitsRemove 00 international prefix
ReplaceSubstitute specific numbersReplace 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 HeaderStandard SIP caller IDMost common choice
Remote-Party-IDCarrier-provided CLIUsed by some carriers
Display NameDisplay-only caller IDMay 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

❓ Frequently Asked Questions

Can I use multiple calendars for the same gateway?

No, each gateway can only be associated with one calendar period at a time. However, you can create multiple gateways with different calendars and use priority to control which gateway is selected during different time periods.

What happens if no calendar matches the current time?

If no calendar period matches the current time, VOS3000 uses the default routing rules based on gateway priority and prefix matching. It’s recommended to have a default gateway configured as a fallback.

How do I configure different routing for different timezones?

VOS3000 uses the server’s local timezone for calendar evaluation. For multi-timezone operations, you need to either adjust calendar times to match the server timezone or deploy separate VOS3000 instances in different timezones.

Can I test calendar routing without making actual calls?

The best way to test is to make test calls during different time periods and verify the gateway selection in CDR. Some operators temporarily adjust calendar times to test without waiting for actual time periods.

Do calendar changes require service restart?

Most calendar changes take effect immediately after applying. However, for major configuration changes or if changes don’t seem to take effect, refreshing the softswitch configuration may be necessary.
