Abstract

A location device for associating a physical location with a communications device. The communications device has assigned device identification and uses an assigned network address for use in routing call data over a communications network. The location device comprises a memory for storing location information related to the physical location and a device port for coupling to the communications device and a network port for coupling to the communications network. The ports are configured for communicating the call data between the ports. The device also has a monitoring module configured for monitoring operation of at least one of the ports in order to detect an initialization process of the communications device, as well as to identify the assigned device identification. The device also has a location registration module configured for communicating a location update message over the communications network via the network port in response to the detected initialization process, such that the location update message including the location information and the identified device identification.
