Counter question: why should a re-INVITE do not update the session timer? E.g. your receive a re-INVITE with a change SDP 2 seconds before the Session expires. Now you do not update the session but terminate the session 2 seconds later!? Is their some higher goal which you are trying to reach by not updating the Session Timer, which I currently do not see?
