A New Internet-Draft is available from the on-line Internet-Drafts directories.
Title : An Extension to the Session Initiation Protocol for
Request History Information
Author(s) : M. Barnes et al.
Filename : draft-barnes-sipping-history-info-01.txt

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. The draft
suggests the use of a secure transport mechanism such as TLS and
the use of S/MIME for ensuring the security of the HistInfo.

In the body type:
"FILE /internet-drafts/draft-barnes-sipping-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.
