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		: The SIP Replaces Header
	Author(s)	: B. Biggs, R. Dean, R. Mahy
	Filename	: draft-ietf-sip-replaces-01.txt
	Pages		: 25

This document proposes a new header for use with the SIP call control
architecture.  The Replaces header is used in peer-to-peer call
control to logically replace an existing SIP dialog with a new SIP
dialog.  This primitive can be used to enable a variety of features,
for example: 'Attended Transfer' and 'Retrieve from Call Park'.  Note
that definition of these example features is non-normative.

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.
