Hi,

If normal Re-invite or UPDATE are processed after session timer is 
negotiated in call, will it extend the session interval for refresh.

For example, A and B negotiates 3600 seconds for session refresh and A is 
the refresher.
Suppose A holds after 500 seconds,i.e A send Re-invite to B, will that 
reinvite refresh the session interval on both A and B.

>From my understanding, session interval will not be refreshed if Re-invite 
or UPDATE do not contain Session-Expires header.
Also, I have seen many UAs not implementing origin field of SDP to 
indicate the session refresh Re-INVITE as only session refresh and not 
offer-answer exchange. Does it mean then both session timer fnctionality 
and offer-answer exchange has to be done for the session-refresh REINVITEs

Please let me know if my understanding is correct.

Thanks,
Udit
