	Title		: Requirements for Session Initiation Protocol (SIP)-based Emergency Calls
	Author(s)	: H. Schulzrinne

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.
