Hello guys,
I'm trying to integrate CUCM with Ericsson PBX via H323 Gateway. The communication from IP Phone to PBX is fine.
But communication from PBX to IP Phone is not working. When i pick up the call, there's no sound for both side, then the call disconnected after awhile. I did submit this case to TAC and sent some log. They said PBX is sending release complete, like normal hang up. Seem like PBX expecting something from IP Phone. After the ip phone picked up, the PBX keep waiting until time out. I don't have an access to the PBX system, so i can't see the debug from PBX side about why they send release complete and what is missing from
Anyone here went through this issue?
I did enable debug h245 events: (2.2.2.2 = PBX; 1.1.1.1 = CUCM)
