1st INVITEW from User-Agent: Cisco-CUCM14.0:
++++++++++++++++++++++++++++++++++++++++
Is it correct to send below param in SDP by Cisco-CUCM??
Video port 0
m=video 0 RTP/AVP 126 97 111
Audio port present but mode = recvonly
m=audio 24624 RTP/AVP 8 0 101
a=recvonly
Proxy is sending INVITE to next hop changing audio port to 0 and sending both m lines with both video and audio port 0
That is causing issue in the next Hop and sending 480 Temporarily Unavailable - claimg that against RFC 3264
