	Title		: A Framework for Application Interaction in the 
			  Session Initiation Protocol (SIP)
	Author(s)	: J. Rosenberg
	Filename	: draft-ietf-sipping-app-interaction-framework-04.txt

This document describes a framework for the interaction between users
   and Session Initiation Protocol (SIP) based applications, and defines
   a new Refer-To header field parameter and option tag in support of
   that framework.  By interacting with applications, users can guide
   the way in which they operate.  The focus of this framework is
   stimulus signaling, which allows a user agent to interact with an
   application without knowledge of the semantics of that application.
   Stimulus signaling can occur to a user interface running locally with
   the client, or to a remote user interface, through media streams.
   Stimulus signaling encompasses a wide range of mechanisms, ranging
   from clicking on hyperlinks, to pressing buttons, to traditional Dual
   Tone Multi Frequency (DTMF) input.  In all cases, stimulus signaling
   is supported through the use of markup languages, which play a key
   role in this framework.

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
