SIP Signaling traverses the Avaya Session Border Controller for Enterprise (SBCE) and the Media must bypass the SBCE.

As far as Avaya Aura® Session Manager (SM) is concerned, all Remote Worker phones are registering from an IP address equal to the Avaya Session Border Controller for Enterprise (SBCE) Remote Worker Private IP address.
