Title : Using the Session Initiation Protocol REGISTER Method To Obtain an Emergency Dialstring
Author(s) : J. Polk
Filename : draft-polk-ecrit-emergency-dialstring-00.txt
Pages : 17
Date : 2006-2-28
Most efforts to address emergency calling challenges over IP (and
cellular technologies such as GSM, TDMA, CDMA, etc, for that matter)
have focused on locating the calling user in order to route the
emergency call set-up request to the appropriate Public Safety
Answering Point (PSAP). Little or no effort to date has focused on
informing the caller what dialstring sequence they may need to use
to initiate a call for emergency help. This document describes how
the Session Initiation Protocol (SIP) REGISTER Request message is
used to inform a user of which emergency dialstring (of the 60 known
dialstring choices around the world) they should use, for where they
are geographically.

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
