9.1. Avaya Aura® Communication Manager Verifications
This section illustrates verifications from Communication Manager.

9.1.1 Example Incoming Call from PSTN via Verizon IPCC to Telephone

Incoming PSTN calls arrive from Verizon at Avaya SBCE, which sends the call to Session
Manager. Session Manager sends the call to Communication Manager. On Communication
Manager, the incoming call arrives via signaling group 2 and trunk group 2.
The following edited Communication Manager list trace tac trace output shows a call incoming
on trunk group 2. The PSTN telephone dialed 866-850-6850. Session Manager mapped the number
received from Verizon to the extension of a Communication Manager telephone (x12003).
Extension 12003 is an IP Telephone with IP address 10.64.91.157 in Region 1. Initially, the G450
Media Gateway (10.64.91.81) is used, but as can be seen in the final trace output, once the call is
answered, the final RTP media path is "ip-direct" from the IP Telephone (10.64.91.157) to the
"inside" of the Avaya SBCE (10.64.91.50) in Region 2.
