Hi all,
I have some questions:-
1) Why as per RFC 3262, the Offer-Answer is a MUST in the Provisional
Resp+PRACK phase?
2) If the 3262 is only for Reliability of Provisional responses, Why should
it mandate Offer-Answer completion?
3) As per current recommendations (that are evolved as per discussions in
the sip groups), Why we can not send new Offer in the 200 OK to the INVITE,
after establishing the early media?
4) If we can not change the media using 200 OK to INVITE, how this early
Media is useful?
5) Are we seriously missing some thing in 3262, that forced us to come up
with 3311 (UPDATE)?
Thanks in advance,
rgds,
Prince
