Hi all,
I recently ran into an intro issue with some unknown SIP device. My client uses
a per-stream SDP connection line, but when a stream is disabled (port set to 0)
the stream is just reduced to the m= line.
Technically I could put the connection line at the session level in some cases,
but it could be that I need to have it at the stream level. Should I also add
it for disabled streams? FWIW, doing so made the aforementioned SIP device
happy, but I couldn’t find any RFC reference which stated it’s always required.
Any clarification (or recommendation) would be appreciated, thanks!
As others have commented, I think you MUST have *some* c-line for each
m-line, whether disabled or not.
If it makes your logic simpler, you could *always* have a token c-line
(e.g., "c=IN IP4 0.0.0.0") at the session level, and then a separate
c-line for each non-disabled m-line.
Thanks,
Paul
