Hi all ,
I have been executing the following scenario :
UAC UAS
INVITE
----------------------------------------->
180(100rel and without SDP)
<------------------------------------------
200 OK
<--------------------------------------------
As per the RFC 3262 section 3 UAS Behavior :
" The UAS MAY send a final response to the initial request before
having received PRACKs for all unacknowledged reliable provisional
responses, unless the final response is 2xx and any of the
unacknowledged reliable provisional responses contained a session
description."
Does this implies that UAS can send 200 OK final response to initial INVITE
before receiving the PRACK for the unacknowledged provisional response without
SDP?
If the above scenario is possible than when should UAS free the RPR
transaction as the RFC 3262 states that UAS should be able to process the PRACK
for the unacknowledged provisional response even after sending the final
response.
Thanks and regards
Jatin Kohli
