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 Relevance2.5.1 Routing GatewayVendor gateway settingsCaller prefix, caller rewrite2.5.1.2 Mapping GatewayCustomer gateway settingsCaller rewrite rules2.5.2 Phone ManagementPhone/extension settingsDisplay caller ID4.3.5 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 CaseBlankAllow all lengthsNo restriction11Only 11-digit numbersUS/Canada mobile format10, 1110 or 11-digit numbersUS numbers with/without 10Block 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 ExampleAllowOnly specified prefixes passAllow 1,44,86 – only US, UK, China callersForbiddenSpecified prefixes blockedForbidden 88 – block Bangladesh prefixAllow (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 ExampleAdd PrefixPrepend digits to caller IDAdd 1 to US numbersRemove PrefixStrip leading digitsRemove 00 international prefixReplaceSubstitute 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 ConsiderationFrom HeaderStandard SIP caller IDMost common choiceRemote-Party-IDCarrier-provided CLIUsed by some carriersDisplay 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
