A New Internet-Draft is available from the on-line Internet-Drafts directories.
This draft is a work item of the Session Initiation Protocol Working Group of the IETF.
Title : SIP Caller Preferences and Callee Capabilities
Author(s) : H. Schulzrinne, J. Rosenberg
Filename : draft-ietf-sip-callerprefs-04.txt
Pages : 27
Date : 15-Jun-01
This document describes a set of extensions to SIP which allow a
caller to express preferences about request handling in servers.
These preferences include the ability to select which URIs a request
gets routed to, and to specify certain request handling directives in
proxies and redirect servers. It does so by defining three new
request headers, Accept-Contact, Reject-Contact and Request-
Disposition, which specify the callers preferences. The extension
also defines new parameters for the Contact header that describe the
characterstics of a UA.

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.
