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. Upon completion of the reprogramming and the release of the telephone line by the user the microprocessor automatically seizes the telephone line and dials the correct codes and telephone number into the telephone company system to either cancel or reprogram the call forwarding telephone number as required. Audio voice prompts as well as audio feedback of the actual numbers programmed into the dialer are provided.
