| 1. An emergency system, comprising:
a gateway;
a database in communication with the gateway; wherein the database comprises:
first routing information for establishing a first communication link between a communication device and a controller;
second routing information for establishing a second communication link between the gateway and the controller, wherein the
second routing information is correlated to the first routing information; and
location data associated with the communication device;
wherein upon receiving identification information related to the communication device, the gateway retrieves the first routing
information from the database and provides the first routing information to a switch, the gateway retrieves the second routing
information from the database and using the second routing information establishes a second communication link with the controller,
and the gateway retrieves the location data from the database.
