RFC4028 · Session Timers in the Session Initiation Protocol (SIP)

Session Timers in the Session Initiation Protocol (SIP)

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. [STANDARDS-TRACK]
