CCM 4.1 to Avaya integration

[tanmaydevare]

Hi,

We have integrated Avaya S8720 with CCM 4.1 as a H323 gateway and also configured appropriate route patterns on CallManager pointing to this gateway. Now, we are able to make calls from IP phones registered to CCM to IP phone registered to Avaya PBX but vice-versa not working.

Help us to troubleshoot this issue.

Tanmay, crossverify if you have done appropriate configuration on the Avaya PBX.
