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.
