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 : An Extension to the Session Initiation Protocol for Request History Information
Author(s) : M. Barnes
Filename : draft-ietf-sip-history-info-01.txt
Pages : 25
Date : 2003-10-23
This draft defines a standard mechanism for capturing the history
information associated with a SIP request. This capability enables
many enhanced services by providing the information as to how and why
a call arrives at a specific application or user. This draft defines
a new optional SIP header, History-Info, for capturing the history
information in requests. A new option tag, HistInfo, to be included
in the Supported header is defined to allow UAs to indicate whether
the HistInfo should be returned in responses to a request which has
captured the history information.

In the body type:
"FILE /internet-drafts/draft-ietf-sip-history-info-01.txt".
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.
