[cisco-voip] Routing calls from PRI inbound MGCP to outbound MGCP T1 CAS

[Wydra, Jason]

The PRI and CAS ports both show G711 when they connect. The PRI disconnect cause is 41 (temporary failure).
 
I should also mention that if I place a call from an internal IP phone directly to the T1 CAS, the call connects to the IVR no problem.

Calls getting dropped on connect are usually a sign of codec 
mismatch.   What is the disconnect cause on the PRI side?

Hello - I am trying to place an inbound call into a 2851 using a MGCP 
controlled PRI. When this call gets to CCM, I have a translation 
pattern that translates the called number to a 4 digit extension on 
my legacy IVR. The 4 digit extension is then sent out a H323 
controlled T1 CAS trunk on the same 2851. I can see the call go 
through when I call the number from my cell phone. It seizes a PRI 
channel and a CAS channel. I hear 1 ring from the IVR and then the 
call disconnects. I can see on the IVR GUI that a channel is also 
seized and it starts to play a greeting. I don't believe the IVR is 
hanging up because I lose my connection while I still see the IVR 
playing a greeting. Any thoughts on how I can fix this?

Thanks,
Jason
