The issue now is CUCM never sends an SDP. Not in the INVITE, not in the ACK. If the INVITE contained an SDP you'd be fine with the default configuration. If it didn't but the ACK did you'd be fine with 3pcc enabled. Right now CUCM isn't providing either. That's your problem, it's somewhere on the Cisco side, and I've never seen it before. Unfortunately I don't have any specific recommendations for you. On Thu, Jul 21, 2011 at 8:46 AM, David Martin <adavidm@gmail.com> wrote:

Kristian, Here are some screenshots from the trunk config. http://img200.imageshack.us/img200/9405/siptrunk.png and for the sip profile http://img191.imageshack.us/img191/3863/sipprofile.png I have tried the early media option both ways with the same result. Is the MTP payload type correct? Appreciate your help on this. David

David,
The problem here is that even with 3pcc enabled the ACK from CallManager doesn't have an SDP. CallManager never provides an SDP during this entire trace. Not in the INVITE (preferred) and not in the ACK (as I already mentioned).
This is odd, even for CallManager. Are you sure you have MTP enabled:

Line 7 is the 200 OK response to the INVITE.

Forgive my confusion, I'm new to freeswitch. Does the invite not start at line 7 on the pastebin?
