Analog/digital voice storage cellular telephone

A voice storage telephone operating in cooperation with one of a plurality of transceiver stations and answering calls without subscriber intervention having a transceiver for transmitting to and receiving voice messages from a remote caller via said one transceiver station, said voice storage telephone comprising:

• a receiving circuit responsive to a call notification signal from said one transceiver station;
• call answering circuitry automatically answering incoming calls from said one transceiver station, said call answering circuitry automatically activated without user intervention after a predetermined period of time subsequent to receiving said call notification signal and generating an off-hook enable signal;
• detection circuitry connected to said call answering circuitry, said detection circuitry sensing a clear channel signal transmitted from said one transceiver station and generating a detection enable signal;
• transmission circuitry connected to said detection circuitry, said transmission circuitry transmitting a prerecorded message to said one transceiver station responsive to said clear channel signal and said off-hook enable signal from said call answering circuitry;
• a message recording circuit digitally recording said voice messages, said message recording circuit responsive to an end of said pre-recorded message;
• and
• playback circuitry coupled to said message recording circuit and reproducing said voice messages.

A voice storage telephone operating in cooperation with one of a plurality of transceiver stations and answering calls without subscriber intervention having a transceiver for transmitting to and receiving voice messages from a remote caller via said one transceiver station, said voice storage telephone comprising:

• a receiving circuit responsive to a call notification signal from said one transceiver station;
• call answering circuitry automatically answering incoming calls from said one transceiver station, said call answering circuitry automatically activated without user intervention after a predetermined period of time subsequent to receiving said call notification signal and generating an off-hook enable signal;
• a message recording circuit digitally recording said voice messages transmitted at a first frequency by said one transceiver station, said message previously recorded at said one transceiver station at a second frequency, lower than said first frequency, said message recording circuit responsive to said off-hook enable signal from said cell answering circuitry;
• and
• playback circuitry coupled to said message recording circuit and reproducing said voice messages at a normal speech frequency.

A voice storage telephone operating in cooperation with one of a plurality of transceiver stations and answering calls without subscriber intervention having a transceiver for transmitting to and receiving voice messages from a remote transceiver via said one transceiver station without intervention by a subscriber, said voice storage telephone receiving a personal identification code entered by a caller at said remote transceiver and comprising:

• a receiving circuit responsive to a call notification signal from said one transceiver station;
• a detector for verifying the presence of a clear channel signal received from said one transceiver station;
• call answering circuitry responsive to said detector for generating an off-hook enable signal;
• a register having a prestored code;
• a comparator comprising said personal identification code with said prestored code;
• and
• call terminating circuitry responsive to said comparator for terminating a call when said personal identification code does not match said prestored code.

A method for receiving, recording and reproducing voice messages from a remote transceiver via one transceiver station and answering calls without intervention by a subscriber, said method comprising the steps of:

• receiving a call notification signal from said one transceiver station;
• automatically answering an incoming call from said one transceiver station without user intervention after verification of a clear channel subsequent to receiving said call notification signal and generating an off-hook enable signal;
• transmitting a pre-recorded message to said one transceiver station in response to said verification of said clear channel;
• digitally recording said voice messages in response to an end of said pre-recorded message;
• and
• reproducing said voice messages in response to an operator command.
