In this section:
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.
At a high level, the functions performed by the EATF are:
SBC IMS Deployment - A-SBC as EATF Provisioning
EATF call flow
