1. In a radio interface apparatus coupling a land-type telephone instrument to a radio transceiver for coupling the telephone instrument to a radio network, said interface comprising a microprocessor and memory means, a method of automatically determining the generation of a send-signal to the transceiver upon the detection of the end-of-dialing of a telephone number entered into the telephone instrument, said method comprising:

  • (a) storing a list of telephone numbers that have been previously-dialed telephone numbers on the telephone instrument coupled to the radio interface apparatus;

    (b) comparing a currently-dialed telephone number entered by the telephone instrument to the list of previously-dialed telephone numbers;

    (c) determining if the currently-dialed telephone number matches one of the previously-dialed telephone numbers of the list of previously-dialed telephone numbers;

    (d) determining an end-of-dialing detection method to utilize; and

    (e) generating a send-signal command in response to said step (d) to the transceiver for transmission over the radio network;

    said step (b) comprising comparing the first dialed digit of the currently-dialed telephone number with all of the first digits of the previously-dialed telephone numbers of the list of previously-dialed telephone numbers.
