Third-Party Authentication for Session Initiation Protocol (SIP)
draft-ietf-sipcore-sip-authn-02
Abstract
This document defines an authentication mechanism for SIP, that is
based on the OAuth 2.0 and OpenID Connect Core 1.0 specifications, to
enable the delegation of the user authentication to a dedicated
third-party IdP entity that is separate from the SIP network elements
that provide the SIP service.
