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,

 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:
