Usage of the Session Description Protocol Alternative Network Address Types Semantics in the Session Initiation Protocol
RFC 4092, “Usage of the Session Description Protocol Alternative Network Address Types Semantics in the Session Initiation Protocol”, is a Proposed Standard document published in June 2005 by G. Camarillo, J. Rosenberg. It has been obsoleted by RFC 5245 — refer to the newer document for the authoritative version. The canonical text is published by the RFC Editor.
Abstract
This document describes how to use the Alternative Network Address Types (ANAT) semantics of the Session Description Protocol (SDP) grouping framework in SIP. In particular, we define the sdp-anat SIP option-tag. This SIP option-tag ensures that SDP session descriptions that use ANAT are only handled by SIP entities with ANAT support. To justify the need for such a SIP option-tag, we describe what could possibly happen if an ANAT-unaware SIP entity tried to handle media lines grouped with ANAT. [STANDARDS-TRACK]
What “Proposed Standard” means
An entry-level standards-track specification: stable, peer-reviewed and a solid basis for implementation, though it may still evolve before becoming an Internet Standard.
