Hi list,
Just joined and hope that this is not too dumb of a question nor has it been answered before:
given a UA receives an SDP offer in a resonse (e.g. the 200 OK of its previous INVITE), and realizes it has no
means of dealing with the offered media (e.g. one medai entry with a single codec description which is not compatible with the one of the receiving UA). RFC 6337 state that:
"When a UA receives a response with an offer that it cannot accept,
the UA does not have a way to reject it explicitly. Therefore, a UA
should respond to the offer with the correct session description and
rearrange the session parameters by initiating a new offer/answer
exchange, or alternatively terminate the session"
the UA does not have a way to reject it explicitly. Therefore, a UA
should respond to the offer with the correct session description and
rearrange the session parameters by initiating a new offer/answer
exchange, or alternatively terminate the session"
What does "correct" session description mean in this context?
1- the SDP the UA would be able to accept (basically like sending an offer?
2- an answer according to RFC3264, where the media entry has a RTP port of 0 indicating that the media is not accepted?
(I would vote for 2 since it would follow the more general SDP offer/answer procedure, but not sure)
Thanx and regards
Harry
