This document examines the scenarios within which SIP phones may be
used to contact emergency call centres. Beginning with an overview
of the high level system requirements for contacting emergency call
centres in the PSTN, the scenarios involving stationary or nomadic
SIP phones are described and then alternative strategies for
supporting the information flows for the scenarios needed to meet
these requirements are examined. The major finding from the point
of view of SIP standardization is it would be helpful in a number of
scenarios if a location header field could be added either by the
SIP phone or by a proxy to indicate the location of the phone in a
machine-readable way.

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
