Hi,
I have a question related to Sip extension called session-timers, and I would appreciate if you find a time to answer it.
From Session-timers draft I don't see how can refresher turn-offsession-timers in the middle of dialog?
In the draft (version 15) page 13 it is said: "In a session refresh
request sent within a dialog with an active session timer, the Session-Expires header field SHOULD be present". But it does not
say that if it is not present session-timers should be turned-off, is it supposed to say that?
However, for the other side it is explicitly said that sending 2xx replay to refresh without Session-Expires filed will turn extension off.
I think you just send a reinvite (or update) without a Session-Expires. This probably can't technically be considered a refresh request, since it isn't refreshing the timer. But you might was well consider it an "unrefresh" request. Either side should be able to do this at any time.
