Hi

You can just put two m=audio... line there. But the big problem is that most of the devices will not support it, so it will be useless unless you plan to use it only between your sip phones

two audio streams in SIP

Posted:Tue 10 of Mar, 2009 (18:07 UTC)
Hi all,

I'm developing a SIP phone and I would like to know if there is a way to send two simultaneous audio streams in a SIP session. I have read that adding an extra SDP field "m" doesn't help (some SIP phones don't support it).

thanks in advance,
