A PABX incorporating locating apparatus has a plurality of receivers each located in proximity to or within an extension telephone set and also has a plurality of transceivers. Each transceiver is intended to be carried by a person normally present within the building in which the PABX is installed and is arranged to transmit to the nearest receiver information about the identity and personal status of the carrier of that transceiver. The PABX is arranged to respond to that identity and personal status by, for example. routine incoming calls to the extension telephone set nearest the carrier of that transceiver. |
