[MMUSIC] SDPCapNeg question
Hi
Reading the SDPCapNeg draft and esp. the syntax in 3.5.1 I get the idea that it is possible to formulate an SDP like
m=audio 54320 RTP/AVP 0
a=tcap:1 RTP/AVPF
a=pcfg:1
in other words just an empty potential configuration.
Even though this is close to stupidity I just want to make sure that it is possible (and no ... I don't see any use case at all). Also it does not seem to break the syntax as far as I can see in 3.5 and 3.6.
Speaking of the [...] and (...) in the syntax , I have tried to find the document that describes these and their exact meanings, where do I find this info ?(need to make the syntax in the image attribute draft correct).
