This draft is a work item of the Session Initiation Protocol Working Group of the IETF.
Title : SIP Extensions for Media Authorization
Author(s) : W. Marshall et al.
Filename : draft-ietf-sip-call-auth-04.txt
Pages : 14
Date : 06-Mar-02
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.

NOTE: The mail server at ietf.org can return the document in
MIME-encoded form by using the "mpack" utility. To use this
feature, insert the command "ENCODING mime" before the "FILE"
command. To decode the response(s), you will need "munpack" or
a MIME-compliant mail reader. Different MIME-compliant mail readers
exhibit different behavior, especially when dealing with
"multipart" MIME messages (i.e. documents which have been split
up into multiple messages), so check your local documentation on
how to manipulate these messages.
Below is the data which will enable a MIME compliant mail reader
implementation to automatically retrieve the ASCII version of the
