Title : Diversion Indication in SIP
Author(s) : S. Levy, B. Byerly, J. Yang
Filename : draft-levy-sip-diversion-04.txt
Pages : 40
Date : 04-Jun-02
This document proposes an extension to the Session Initiation
Protocol (SIP). This extension provides the ability for
the called SIP user agent to identify from whom the call
was diverted and why the call was diverted.
The extension defines a new general header, Diversion, which
conveys the diversion information from other SIP user agents
and proxies to the called user agent.
This extension allows enhanced support for various features,
including Unified Messaging, Third-Party Voicemail, and Automatic Call
Distribution (ACD). SIP user agents and SIP proxies which receive
diversion information may use this as supplemental information for
feature invocation decisions.

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.
