Abstract
A method and apparatus for one-touch recall and dialing of stored telephone or billing account numbers using only the numeric and special keys of a standard 12-key keypad. Upon momentary actuation of a numeric or special key of a standard keypad, the data input is entered into a buffer or directly dialed into a telephone network. If, however, the actuated key is actuated for more than a predetermined amount of time, a previously stored sequence of numbers is retrieved from a memory address location corresponding to the actuated key and is automatically dialed.
