Incoming faxes failing on a 2911 MGCP Gateway

[ReallyRotten]

Inbound faxes are failing and I'm at a loss as to why. I see a "CC_EV_CALL_DIGIT_END" event in the debugs. I've attached the debugs - I ran debug vpm all, debug voip ccapi inout and debug fax relay t30 all-level-1.

If anyone has suggestions, I'll try anything

Can you post a show run?

I bet its because you have all those dial peers that arent needed but since you have them all using port 0/0/0 it might be getting confused. This is the only dial peer you should have:

Ok so let me understand - I don't need any outgoing dial peers? Only an incoming for the fax#?

 

[gnrslash4life]

Correct. MGCP is controlled by CM not the gateway.
