Title : Requirements for Session Policy for the Session
Initiation Protocol (SIP)
Author(s) : J. Rosenberg
Filename : draft-ietf-sipping-session-policy-req-01.txt
Pages : 16

The proxy server plays a central role as an intermediary in the
establishment of sessions in the Session Initiation Protocol (SIP).
In that role, they can define and impact policies on call routing,
rendezvous, and other call features. However, there is no standard
means by which proxies can have any influence on session policies,
such as the codecs that are to be used. As such, ad-hoc and
non-conformant techniques have been deployed to allow for such policy
mechanisms. There is a need for a standards-based and complete
mechanism for session policies. This document defines a set of
requirements for such a mechanism.

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.
