SIP integration Problems

Unanswered Question
Feb 11th, 2008

I have a CUCM 4.1 that I need to integrate with a VoiceBlue (SIP Trunk), but I'm having problems when it tries to call to a different region. All the calls with the regions that use G711 function normaly, but when I try to make a call to a region with G729 the call is dropped.

Does any one have an idea of how I can make this function?

I have this problem too.

u need to allow g.711 for MTP in your SIP trunk as CM 5.0 and below doesn't support G.729 for "INVITE with SDP".
