[SIPForum-discussion] Offer in a 200OK for Invite transaction.

[Manpreet Singh]

For the INVITE transaction where the offer was sent in an INVITE and the
answer coming back in 183, would it be valid to send a new offer in the
200OK? So the question is whether the 200OK can be used to send a "new"
Offer ( different from the answer in 183 ) for the INVITE transaction once
183 has completed the offer/answer part of that transaction. Only UPDATE can
be used for early dialog changes as per my understanding and a 200OK still
constitutes early dialog so it wont be valid to send a new offer in 200OK?
Although 200OK can carry the same SDP as 183 which would mean nothing or
would not be considered as early dialog change in capability.
 
Please correct me if I am wrong.
 
Thanks
