In this section:
The SIP Param Filter Profile includes the following characteristics:
- This profile takes precedence over existing mechanism/flags when transparently passing Allow/Supported/Require headers, but does not impact corresponding configurations established by the operator. It is operators responsibility to ensure the system is configured properly so that transparently-passed values do not conflict with existing configurations. For example, do not configure 100rel as pass-through if 100rel support fro SIP Trunk Group Signaling is disabled.
- The settings of SIP Param Filter Profiles for both ingress and egress legs dictate the actual pass-through results (see SIP Param Filter Profile table below for details.)
- Pass-through of individual header values is configurable.
- SIP tags are provided for unknown SIP parameter transparency only. Known SIP parameter transparency is still determined using existing SBC application logic (from Ingress leg to Egress leg) and configurations.
For additional details, see SBC SIP Transparency Implementation Guide.
Ribbon recommends using the Transparency Profile to configure transparency on the SBC Core for new deployments, as well as applying additional transparency configurations to existing deployments. Do not use IP Signaling Profile flags in these scenarios because the flags will be retired in upcoming releases.
Refer to the SBC SIP Transparency Implementation Guide for additional information.
Command Syntax
The CLI syntax to configure the SIP Param Filter Profile is shown below:
