Hi,
An offer can have 0 or more media streams and an answer must
have the same number. (RFC3264)
A media stream is rejected by using a 0 port value in the
answer. (RFC3264)
m=audio 0 RTP/AVP 99
A UA should return an answer with no media if it gets an
offer with no media. (3PCC)
So, if a UA receives an INVITE with an offer with media streams,
but can support none of them (no codecs in common), should it
return a 200 with an answer containing rejected streams or a
4XX? (488?)
Is the answer the same for an initial INVITE and a re-INVITE?
Thanks,
-troy
