Hi, All I have a client have legacy Avaya Communication manager 5.2.1 and he needs to replace it with 3cx server but in phases due to his budget limitation so requested to make a POC and integrate Avaya CM with 3CX via SIP trunk.. we did the SIP trunking and right now all Avaya h323 endpoint can dial all 3cx users successfully without any issues while the 3cx users are not able to dial Avaya users at all.
troubleshooting that I did is like the following:
1- both trunks are in service and ideal without any issues from Avaya side and from 3CX side
2- trace from Avaya side while 3cx user is dial Avaya user and I didn't find any call is hitting Avaya cm trunk
2- I did trace from 3cx side errors 407 proxy authentication required, sip 408 request timeout.
anyone faced this issue before I really need urgent help as the project might be canceled if we didn't fix it from 3CX side.
