Abstract

By moving a switch, the system can be put into an ENTER mode where a number can be programmed into a memory. Then by putting the switch into an ON mode, any telephone call which comes in will not cause a ringing signal in the tle telephone or extension telephone but will instead start the voice activation system. If the same digits previously entered are again entered, then an enunciation or ringing signal will be produced by the system. The numbers are entered by a voice or manual method so that the caller hears a repetition of numerals such as 'One, Two, Three, Four, etc'. Any sound which is made following any of these digits causes that particular digital value to be entered. When switched to an OFF mode, the telephone will ring normally. The switches can be combined into a single three-position switch. The system may be used in a radio telephone network.
