  • Patent number: 4807279
    Abstract: An apparatus and method is provided for remotely cancelling or reprogramming the call forwarding service provided by the telephone company on the customer/user's telephone line. A microprocessor is utilized in conjunction with external memory provisions as well as a keypad with DTMF-tone generator. The keypad and DTMF-tone generator are provided for inputting the call forwarding code data and preprogrammed telephone number into memory. A ring detector causes the microprocessor to seize the telephone line and automatically dial the preprogrammed telephone number. This allows the customer/user to answer the automatically dialed telephone call at the remote telephone location so that by inputting a proper code number into the line the user may take control of the operation of the device. At this point the preprogrammed telephone number can be cancelled or changed.
