Abstract
A method is provided for tracking the physical location of IP phones and IP devices in a network. According to the invention, the IP phone or IP device detects its own current location and then informs the PBX controller or the location database to which it is connected. The capability is integrated in every IP phone and IP device. The PBX or location database then takes appropriate action, such as updating the ALI mapping for the phone or location information for the IP device.
