摘要

A location device for associating a physical location with a communicationsdevice. The communications device has assigned device identification and usesan assigned network address for use in routing call data over a communicationsnetwork. The location device comprises a memory for storing location informationrelated to the physical location and a device port for coupling to the communicationsdevice and a network port for coupling to the communications network. The portsare configured for communicating the call data between the ports. The devicealso has a monitoring module configured for monitoring operation of at leastone of the ports in order to detect and initialization process of the communicationsdevice, as well as to identify the assigned device identification. The devicealso has a location registration module configured for communicating a locationupdate message over the communications network via the network port in responseto the detected initialization process, such that the location update messageincluding the location information and the identified device identification.
