Title : Requirements for Session Initiation Protocol (SIP)-based Emergency Calls
Author(s) : H. Schulzrinne
Filename : draft-schulzrinne-sipping-emergency-req-01.txt,.pdf

This document enumerates requirements for emergency calls in VoIP and
general Internet multimedia systems. We divide the requirements into
'trunk replacement' and 'end-to-end'. Trunking 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 may also apply to other environments,
such as those using H.248/Megaco, MGCP 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.
Below is the data which will enable a MIME compliant mail reader
implementation to automatically retrieve the ASCII version of the
