A Framework for Session Initiation Protocol User Agent Profile Delivery
Abstract
This document specifies a framework to enable configuration of
Session Initiation Protocol (SIP) user agents (UAs) in SIP
deployments. The framework provides a means to deliver profile data
that user agents need to be functional, automatically and with
minimal or no User and Administrative intervention. The framework
describes how SIP user agents can discover sources, request profiles,
and receive notifications related to profile modifications. As part
of this framework, a new SIP event package is defined for
notification of profile changes. The framework provides minimal data
retrieval options to ensure interoperability. The framework does not
include specification of the profile data within its scope.
