Title : Proxy Authentication of the Emergency Status of SIP Calls
Author(s) : R. Barnes
Filename : draft-barnes-ecrit-auth-00.txt
Pages : 9
Date : 2007-7-5
In order to prevent abuse of emergency calling resources for non-
emergency purposes, operators of SIP proxies require a capability to
distinguish emergency calls from non-emergency calls. This document
describes several mechanisms by which the entities participating in a
call can include in SIP headers a verifiable assertion that the
signaled call is an emergency call.

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.
