The
The SBC supports up to 20 parameters per SIP header to accommodate enhanced services such as IMS and VoLTE using call flows such as ICS and SRVCC.
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.
