A New Internet-Draft is available from the on-line Internet-Drafts directories.
This draft is a work item of the Session Initiation Proposal Investigation Working Group of the IETF.
Title : A Framework for Session Initiation Protocol (SIP) Session Policies
Author(s) : V. Hilt, et al.
Filename : draft-ietf-sipping-session-policy-framework-00.txt
Pages : 28
Date : 2006-4-5
Proxy servers play a central role as an intermediary in the Session
Initiation Protocol (SIP) as they define and impact policies on call
routing, rendezvous, and other call features. However, there is
currently no standard mechanism by which a proxy can influence
session policies such as the codecs or media types to be used. This
document specifies a framework for SIP session policies. It defines
two types of session policies, session-specific and session-
independent policies and introduces a model, an overall architecture
and the protocol components needed for session policies.

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
Internet-Draft.
