Proxy servers play a central role as an intermediary in the
establishment of sessions in the Session Initiation Protocol (SIP).
In that role, they define and impact policies on call routing,
rendezvous, and other call features. However, there is currently no
standard means by which network elements can have any influence on
session policies, such as the codecs that are to be used. In this
document, we propose a complete and standards-based framework that
enables intermediaries to request the use of policies in a SIP
session.

In the body type:

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.
