Cisco to Avaya VDN on-net call - after announcement can not be heard both directions

Cisco to Avaya VDN on-net call - after announcement can not be heard both directions

Cisco to Avaya VDN on-net call - after announcement can not be heard both directions

(OP)

Hi All- I need some help, please. We have recently been acquired by a company using Cisco CUCM 9.2 and we use Avaya (Aura 6.2); both company's have multiple help-desk type offices internationally.
We are connected by H.323 ISDN lines.
Direct on-net Cisco/Avaya extension to extension calls are working fine.
The problem happens when Cisco VDN is forwarded to an Avaya DID VDN⇒vector with announcements to skilled agent. The calls get to the agent but can't be heard in either direction. This happens even with music- I can only get it to work if I send directly to skilled agent.
The trace looks like it should be working correctly:


We updated our codex set for the ip-network-region to include G.711 for the Cisco calls to hear the announcements.


The one thing I noticed during testing was the ring-back normally heard before agent picks up could not be heard by the cisco call.

We have created work a around that send the calls through Cisco VDN to POTS line to the Avaya VDN of the other office for the helpdesk calls.
I appreciate any help--
Becky

Thanks for the info. The media termination point is checked; any other suggestions.
