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

[Jason Aarons (US)]

If you select use MTP resource it may work (CCMAdmin/Gateway), but this
is bad as it uses MTP resources. I'd only test with it and open a TAC
case.

This is a hairpinned call.  I've seen caveats in 12.4T with this
scenario only using Unity to forward back out same H323/PRI.
TAC/Multiservice Voice Team never had a fix and we gave up on the
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
