	Title		: SIP 183 Session Progress Message

This document describes a proposed extension of the Session Initia-
tion Protocol.  This extension would add the 183 Session Progress
response message.

The introduction of the 183 informational response message would
allow a called user agent to indicate to the calling user agent
whether or not the calling user agent should apply local alerting for
the session.  The existing 180 Ringing message would indicate that
the calling user agent has the option of providing local alerting
(and generally should).  The 183 Session Progress message would indi-
cate that the calling user agent should not provide local alerting
and should establish a media session to be used by the called user
agent to indicate the status of the session setup request as part of
the indicated media stream.

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.
