Abstract

Determining a physical location of a network device includes determining a network address associated with the network device and correlating the network address with a physical location. The network address associated with the network device is an address of the network device, an address of a router coupled to the network device or an address of an other device at a same physical location as the network device. The other device may be a gas meter or an electric meter. A table may be consulted for the location information.

Claims

1. A method of dispatching emergency services based on a communication from a network device, comprising:

receiving the communication from the network device, the communication initiated by a caller;

determining a network address associated with the network device;

determining whether the network address is associated with a single physical location using a test;

if the network address is associated with a single physical location, identifying location information associated with the network device;

if the network address is not associated with a single physical location;

determining whether the network address has an associated alternative service provider, wherein the alternative service provider is an Internet Service Provider that handles emergency calls on behalf of users of the Internet Service Provider; and

if the network address has an associated alternative service provider, determining whether the alternative service provider can handle the communication,

if the alternative service provider can handle the communication, transferring the communication to the alternative service provider;

if the alternative service provider cannot handle the communication, contacting the alternative service provider for location information;

determining whether contacting the alternative service provider resulted in receiving location information;

if contacting the alternative service provider did not result in receiving location information, having an attendant speak with the caller to obtain location information; and

correlating the location information to identify a public service access point and transferring the communication and the location information to the public service access point.

2. The method of claim 1, wherein the network device is a voice over internet protocol telephone.
