Abstract:
     A PBX is connected to mobile telephony network (40) via a PSTN and via a LAN and data network. A mobile telephone served by the mobile network, has a separate data channel. The invention describes away to integrate mobile telephones as extensions of the PBX and to provide them with functionality similar to that of a wired digital PBX system telephone. The data channel of the mobile telephone is used to give the PBX access to the user interface devices of the telephone. The speech path between the PBX and the mobile telephone may be set up in the direction from the PBX to the mobile telephone, even when the call was initiated at the telephone. The invention relies only on the basic voice and data communications services of the mobile telephony network, and therefore provides independence from the network operator.
