A New Internet-Draft is available from the on-line Internet-Drafts directories. This draft is a work item of the Session Initiation Protocol Core WG of the IETF. Title : Session Timers in the Session Initiation Protocol (SIP) Authors : Christer Holmberg Steve Donovan Jonathan Rosenberg Filename : draft-ietf-sipcore-rfc4028bis-00.txt Pages : 26 Date : 2018-12-21 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.
