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.
