Is there any way to get inbound called id to work on an MGCP gateway on a long distance T-1 CAS. It is configured as e&m wink start. I can see the *ANI*DNIS if I put a Tbird on the line, but callmanager seems to ignore it. All of the research that I have done leads me to believe that to get this to work I will need to convert to H.323 gateway and have carrier send e&m FGD. Is there any other way?
No, caller ID is not currently supported with T1 CAS and MGCP. See the following link. The only option currently is to convert to H.323. As you said, you will also need FGD.
Hope this helps.
