If any of you know the answer, I would be happy with any suggestion.
1. INVITE goes advertising media address and port
2. 183 Ringing with RTP comes back
3. 200 OK (SDP) comes back
4. as the call is up another INVITE is being sent with new media address and port
Is this correct? Shouldn't this be a re-INVITE rather then a normal INVITE in the call?
Any thoughts?
