(SIP)-based Emergency Calls

This document enumerates requirements for emergency calls in VoIP and
general Internet multimedia systems. We divide the requirements into
'last-mile' and 'end-to-end'. Last-mile solutions only exchange the
emergency call center's circuit-switched access by an IP-based
system. The requirements for end-to-end IP-based emergency calling
address functional and security issues for determining the correct
emergency address, for identifying the appropriate emergency call
center and for identifying the caller and its location. While we
focus on systems that employ the Session Initiation Protocol (SIP),
many of the requirements also apply to other environments, such as
those using H.248/Megaco or H.323.

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.
