This document describes a set of extensions to the Session Initiation
Protocol (SIP) which allow a caller to express preferences about
request handling in servers.  These preferences include the ability to
select which Uniform Resource Identifiers (URI) 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 header
fields, Accept-Contact, Reject-Contact, and Request-Disposition,
which specify the caller's preferences.

This document is a product of the Session Initiation Protocol Working
Group of the IETF.

This is now a Proposed Standard Protocol.

This document specifies an Internet standards track protocol for
the Internet community, and requests discussion and suggestions
for improvements.  Please refer to the current edition of the
"Internet Official Protocol Standards" (STD 1) for the
standardization state and status of this protocol.  Distribution
of this memo is unlimited.
