<tt>Hello all!<br>
<br>
Thank you Evandro and Robison for the new emergency module. I bet
the community will find it useful.<br>
<br>
I've added the extra documentation you provided on the wiki[1].
Therefore, anybody who is looking to deploy this feature on their
platform can read and get some ideas about what the module does
and how.<br>
The wiki page contains the following information:<br>
* The specifications and design of the NENA i2 architecture <br>
* Use case scenarios<br>
* Configuration examples<br>
<br>

<div><b>Opensips: Emergency Module - Abstract</b><br>
To make as emergency call using a single code (e.g.: 911 in US
or 112 in Europe) has been a challenge for VOIP technology.
This is a problem because a crucial information is missing:
the user's location and the location is essential to route the
call to the closest PSAP(call center responsible for answering
emergency calls).<br>
<br>
This has been studied by many entities, such as the IETF, who
created several RFC on the topic, and the American NENA
(National Emergency Number Association), who devised a
solution based on the concepts of the IETF. The main elements
of this solution are, LIS (Location information server ,which
is the node that determines the location of the VoIP
terminal), ERDB (servers that determines the area's emergency
closest PSAP due this location ), VPC (servers that manage the
location and routing information associated with a call) and,
most importantly, the SIP PROXY that can make routing the call
according to the data sent by these servers.<br>
<br>
The OpenSIPS can be an element in this architecture acting as
a SIP proxy, but need to meet the requirements of this
solution. To provide this we have developed the Emergency
Module, which basically makes the interface with the servers
mentioned and adds the new SIP extensions that the IETF has
created for this purpose. Including only two commands and some
parameters in your configuration file, we enable OpenSIPS to
be an important component in the solution of this problem,
with great potential to meet American market or other
countries that could adopt a similar architecture.<br>
