[cisco-voip] transcoding from g711 to g729 with CME

[Hinson, Greg]

I have a client that is using CME at a remote store and Enterprise
CallManager at the host location. I have regions setup, forcing the
calls destined for the remote location to g729. The CME hardware is a
2821 platform running 12.3.14T7 spservices IOS with an NM-CUE module.
Using a gatekeeper to interconnect the two callmanagers, I can
successfully negotiate a g729 call across the network, but on a CME
call-forward-no answer condition to Unity Express, the call drops with a
fast busy. I followed the guidelines referenced in the doc below for
creating a dspfarm/sccp profiles and its assignment to
telephony-service, but with no success. I also upgraded the IOS to
12.4.3, thinking it was an incompatibility issue with 12.3.14, and I
have the same problem.  Any ideas?
