[Sip] I-D ACTION:draft-ietf-sip-session-timer-05.txt



A New Internet-Draft is available from the on-line Internet-Drafts directories.
This draft is a work item of the Session Initiation Protocol Working Group of the IETF.

	Title		: SIP Session Timer
	Author(s)	: S. Donovan, J. Rosenberg
	Filename	: draft-ietf-sip-session-timer-05.txt
	Pages		: 28
	Date		: 24-Jul-01
	
This document proposes an extension to the Session Initiation
Protocol (SIP). This extension allows for a periodic refresh of SIP
sessions through a re-INVITE. The refresh allows both user agents and
proxies to determine if the SIP session is still active. The
extension defines a new general header, Session-Expires, which
conveys the lifetime of the session.

In the body type:
	"FILE /internet-drafts/draft-ietf-sip-session-timer-05.txt".
	
NOTE:	The mail server at ietf.org can return the document in
	MIME-encoded form by using the "mpack" utility.  To use this
	feature, insert the command "ENCODING mime" before the "FILE"
	command.  To decode the response(s), you will need "munpack" or
	a MIME-compliant mail reader.  Different MIME-compliant mail readers
	exhibit different behavior, especially when dealing with
	"multipart" MIME messages (i.e. documents which have been split
	up into multiple messages), so check your local documentation on
	how to manipulate these messages.
		
		
Below is the data which will enable a MIME compliant mail reader
implementation to automatically retrieve the ASCII version of the
Internet-Draft.
