Hello all,
I have some questions about SIP Transaction:
1. When UAS receives an INVITE request for the first time, does the Tansaction
Layer of UAS
create an INVITE Server Transaction for this INVITE, or does by TU?
2. When UAS has sent 200 OK to an INVITE, the INVITE Server Transaction for that
INVITE is
destroyed then, but when UAS receives ACK for the 200 OK, using rules described
in 17.2.3(RFC3261), no Transaction will match this ACK , and will the ACK be sent to
TU directly?
Thanks a lot!
