Abstract: A cordless telephone arrangement, such as a DECT Business Cordless Telecommunications (BCT) system, comprises a PBX base station (1) and a plurality of mobile stations in the form of portable handsets (2a, 2b . . . 2n). The handsets themselves include no means for independently dialing a telephone number. Instead of a conventional keypad the handsets each comprise only a single “TALK” key 7. The PBX 1 is adapted to dial on behalf of each handset in response to an instruction received by radio communication therefrom. In one embodiment the instructions are delivered orally to the handset. In this case the PBX includes a voice recognition device 12. A voice synthesizer 11 may also be included for returning spoken messages to the handset. The TALK key 7 is used to indicate that the handset is required to make a call, to terminate a call, or to accept an incoming call.

Abstract: A portable radio telephone operating under the control of a microprocessor includes a disturbance sensitive switch sensitive to shock, movement or other physical disturbance or to a voice which causes the telephone to go "off-hook" if the telephone is disturbed during an incoming call. The user can thus answer an incoming call very quickly before the system times-out the call by gently striking or simply moving the telephone or talking or shouting to it even when the telephone is in a relatively inaccessible location. In a preferred embodiment the user is required to confirm the off-hook condition by pressing one of the keys on the telephone keypad. The telephone may continue ringing until the confirmatory keystroke has been effected.
