The SBC Core supports downstream forking call flows when Dialog Transparency is enabled. This section describes CLI syntax and parameters for the SIP Trunk Group 'downstreamForkingSupport' object.

For feature functionality and configuration guidance, refer to Downstream Forking Support and Configuring Downstream Forking with Dialog Transparency.

 

IMPORTANT

The Transparency Profile is the recommended method of configuring transparency on the SBC Core for new deployments as well as when 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.
