The SIP routing system creates a new TLS connection if none exists towards the CCE ASM server (10.32.15.8:5061) using the Source IP Address: Port from the Signaling Interface CCE-Sig-Interface configured in CCE-ASM Server Flow.

Finally the call is routed to CCE ASM server. All the responses are routed on the same connection using the same Server Flows that are matched during the INVITE request process.

All media ports are released when the SIP call is disconnected using the BYE method. The counters Maximum concurrent sessions per endpoint/policy for each Endpoint Policy Group PSTN-default-low, CCE-default-low are decreased as the call is released.
