Abstract
This document specifies the Diameter Session Initiation Protocol
(SIP) application. This is a Diameter application that allows a
Diameter client to request authentication and authorization
information. This application is designed to be used in conjunction
with SIP and provides a Diameter client co-located with a SIP server,
with the ability to request the authentication of users and
authorization of SIP resources usage from a Diameter server.
