Problem on Avaya side. You have to engage Avaya Experts

I have the same issue, I registered Avaya SIP phone to Cisco CUCM, and Avaya phone can make calls, but can't receive any calls. 

I've tested the same SIP extension on another soft SIP phone and it worked well. 

RTMT shows that the CUCM send the invite message to the Avaya phone but no response. the call hang after a few seconds. 

I see that this topic marked as solved, but where is the solution, anyone can lep please
