In SIP-based networks, there is a need to provide basic network
media services.  Such services include network announcements, user
interaction, and conferencing services.  These services are basic
building blocks, from which one can construct interesting
applications.  In order to have interoperability between servers
offering these building blocks (also known as Media Servers) and
application developers, one needs to be able to locate and invoke
such services in a well defined manner.

This document describes a mechanism for providing an interoperable
interface between Application Servers, which provide application
services to SIP-based networks, and Media Servers, which provide the
basic media processing building blocks.
