Technical Summary
This document is a rejected alternative proposal to work
completed in the SIP working group.
From the abstract:
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 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.

The IESG has concluded that this work is related to IETF work done
in the SIP and SIPCORE working groups, but this relationship does
not prevent publishing.
IESG Note
This document contains an early proposal to the IETF SIP Working Group
that was not chosen for standardization. Discussions on the topic
resulted in the informational RFC3325 "Private Extensions to the
Session Initiation Protocol (SIP) for Asserted Identity within Trusted
Networks", and the standard solution that was chosen can be found in
RFC 4244 "An Extension to the Session Initiation Protocol (SIP) for
Request History Information".
