Hello all!
Thank you Evandro and Robison for the new emergency module. I bet the
community will find it useful.
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.
The wiki page contains the following information:
* The specifications and design of the NENA i2 architecture
* Use case scenarios
* Configuration examples

*Opensips: Emergency Module - Abstract*
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).
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.
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.
For details on usage scenarios, configuration params, etc, see the
online documentation at:
