A New Internet-Draft is available from the on-line Internet-Drafts directories.
This draft is a work item of the SIP for Instant Messaging and Presence Leveraging Extensions Working Group of the IETF.

	Title		: SIP Extensions for Presence
	Author(s)	: J. Rosenberg
	Filename	: draft-ietf-simple-presence-04.txt
	Pages		: 39
	Date		: 30-Nov-01
	
This document proposes an extension to SIP for subscriptions and
notifications of user presence. User presence is defined as the
willingness and ability of a user to communicate with other users on
the network. Historically, presence has been limited to 'on-line' and
'off-line' indicators; the notion of presence here is broader.
Subscriptions and notifications of user presence are supported by
defining an event package within the general SIP event notification
framework. This protocol is also compliant with the Common Presence
and Instant Messaging (CPIM) framework.

In the body type:

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.
