A New Internet-Draft is available from the on-line Internet-Drafts directories.
Title : 3G Wireless Support in the SIP/SDP Static
Dictionary for Signaling Compression (SigComp)

While using SIGComp [4] based compression in SIP/SDP [5] [6], it is
imperative to have access to a static dictionary to be used on the
first SIP message that the compressor sends out. The session set up
time can be reduced significantly if the compression rate of the
first SIP message is considerably high.
The existing static dictionary for SIP and SDP [2], however, does not
include some wireless specific data elements. This document
introduces these new data elements that are specific to various
wireless access technologies. These new data elements are part of the
first SIP message (i.e., originating SIP Invite) used to initiate a
session.

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.
