| Abstract
|
This document describes a framework and requirements for the
interaction between users and Session Initiation Protocol (SIP) based
applications. 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.
