Title : Diversion Indication in SIP
Author(s) : S. Levy, B. Byerly, J. Yang
Filename : draft-levy-sip-diversion-09.txt
Pages : 50
Date : 2009-5-1
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.
