              The Session Initiation Protocol (SIP) OAuth
                    draft-yusef-sipcore-sip-oauth-01

Abstract

   This document defines an authorization framework for SIP that is
   based on the OAuth 2.0 framework, and adds a simple identity layer on
   top of that, based on the OpenID Connect Core 1.0, to enable Clients
   to verify the identity of the End-User based on the authentication
   performed by an Authorization Server, as well as to obtain basic
   profile information about the End-User.
