Private Session Initiation Protocol Extensions for Media Authorization
RFC 3313, “Private Session Initiation Protocol Extensions for Media Authorization”, is an Informational document published in January 2003 by W. Marshall. The canonical text is published by the RFC Editor.
Abstract
This document describes the need for QoS and media authorization and defines a SIP extension that can be used to integrate QoS admission control with call signaling and help guard against denial of service attacks. The use of this extension is only applicable in administrative domains, or among federations of administrative domains with previously agreed-upon policies, where both the SIP proxy authorizing the QoS, and the policy control of the underlying network providing the QoS belong to that administrative domain or federation of domains.
