Hi,
I have a doubt regarding draft-ietf-sip-session-timer-09.txt. The
draft specifies that UPDATE request can be used to refresh session. The
doubt here is how should the UAS behave if an UPDATE comes without
Session-Expires header.
1. Should it treat that UAC is requesting the removal of Session-Timer
feature (As is done in case of re-INVITE without Session-Expires).
2. Should it process the current UPDATE normally and still expect a
re-INVITE or UPDATE to refresh the session.
TIA,
-Vasanth
