When an emergency call is sent to a Public Safety Answering Point
(PSAP), the originating device, the access network provider to which
the device is connected, and all service providers in the path of the
call have information about the call, the caller, or the location,
which is helpful for the PSAP to have in handling the emergency.
This document describes data structures and mechanisms to convey such
data to the PSAP.  The intent is that every emergency call carry as
much of the information described here as possible using the
mechanisms described here.

The mechanisms permit the data to be conveyed by reference (as an
external resource) or by value (within the body of a SIP message or a
location object).  This follows the tradition of prior emergency
services standardization work where data can be conveyed by value
within the call signaling (i.e., in the body of the SIP message) or
by reference.

This document is a product of the Emergency Context Resolution with Internet Technologies Working Group of the IETF.

This is now a Proposed Standard.

STANDARDS TRACK: This document specifies an Internet Standards Track
protocol for the Internet community, and requests discussion and suggestions
for improvements.  Please refer to the current edition of the Official
Internet Protocol Standards (https://www.rfc-editor.org/standards) for the 
standardization state and status of this protocol.  Distribution of this 
memo is unlimited.
