Hi all,

I'm sending an INVITE with two m= lines, one audio, one video. The response I 
receive only accepts the audio stream - port = 0 for the video related m= line.
There is no global connection address and the audio description does contain a 
c= line. The video description does not.

As far as I can tell, a c= line is mandatory regardless of whether the port is 
zero or not but I can't think of any problem with accepting it anyway as the 
video is being rejected and the audio description is fine.
Can anyone think of any possible problems if I accept this SDP? Or perhaps 
point me to the spec that says this is fine if I've missed something? It is the 
simplest of changes for me to allow it but at the moment I'm clearing the call 
down which seems a bit harsh.

Cheers
