This document presents a list of requirements in support of Emergency
Telecommunications Service (ETS) within the context of IP telephony.
It is an extension to the general requirements presented in RFC 3689.
Solutions to these requirements are not presented in this document.
Effective telecommunications capabilities can be imperative to
facilitate immediate recovery operations for serious disaster events,
such as, hurricanes, floods, earthquakes, and terrorist attacks.
Disasters can happen unexpectedly, at any time or place. Quick
response for recovery operations requires immediate access to any
public telecommunications capabilities at hand. These capabilities
include: conventional telephone, cellular phones, and Internet
access via online terminals, IP telephones, and wireless Personal
Digital Assistants (PDAs). The commercial telecommunications
infrastructure is rapidly evolving to Internet-based technology.
Therefore, the Internet community needs to consider how it can best
support emergency management and recovery operations.
The key words "MUST", "MUST NOT", "REQUIRED", "SHALL", "SHALL NOT",
"SHOULD", "SHOULD NOT", "RECOMMENDED", "MAY", and "OPTIONAL" in this
document are to be interpreted as described in .

RFC 3690 ETS Telephony Requirements February 2004
Standards have been developed by other standards bodies concerning
emergency communications. As discussed in , some of these
standards, such as T1.631 , define specific indicators or labels
for emergency communications in Signaling System 7 (SS7) networks.
Certain requirements must be defined in order to achieve peering
across hybrid networks (networks that communicate between IP and
other types of networks, such as that realized by the Public Switched
Telephone Network) in order to achieve an interworking of services.
 has defined a set of general system requirements to support
Emergency Telecommunications Service (ETS). This document defines an
additional set of system requirements to achieve support for ETS
within the specific context of IP telephony (note that this document
views IP telephony within the context of an end-to-end application
layer service). Solutions to requirements are not defined. The
document does not specify protocol enhancements or specifications.
Note that , Requirements for Resource Priority Mechanisms for the
Session Initiation Protocol (SIP), is an RFC that shares some overlap
with this document. However...
