[cisco-voip] Cisco 2821 & Nortel MICS Back-to-Back (PRI) Issues

[Gary T. Giesen]

I've got a Cisco 2821 with a PRI card configured with SIP trunking. I'm
trying to interface with a PRI card on a Nortel MICS. Incoming calls work
fine, but outgoing calls (from the perspective of the MICS) ring and die a
half second after the called party picks up.

I've including some debug, but not sure what's relevant (I'm not a TDM guy)
so let me know what else you need...
