Abstract:
   This document defines an extension to the Session Initiation Protocol
   (SIP).  This extension allows for a periodic refresh of SIP sessions
   through a re-INVITE or UPDATE request.  The refresh allows both user
   agents and proxies to determine whether the SIP session is still
   active.  The extension defines two new header fields: Session-
   Expires, which conveys the lifetime of the session, and Min-SE, which
   conveys the minimum allowed value for the session timer.
