HI All,
If the intial INVITE contains an SDP offer and the next 200 OK for that
INVITE carries the answer, but the answer (in the 200 OK) is not acceptable

resonable offer in the ACK (where would be the answer?) and send a fresh
UAC will ACK the 200 OK and then send BYE.
But why would the answer be not acceptable? It is a subset of the offer
from UAC.

Hi All,

wishes to add a resource type to the existing session. So UAC sends a re-INVITE
to the UAS and UAS responds with a 200 OK. Now my query is, whether there will
be a case in which, the answer sent in the 200
