Claim:
A system for generating number tones for dialing a telephone device comprising: a first housing associated with the telephone device; a socket assembly defining at least one socket, where the socket assembly is supported by the first housing and the socket is electrically connected to the telephone device; a first memory device for storing a sequence of numbers; a first data entry device associated with the first memory device; a converter for generating an electrical DTMF signal comprising a sequence of DTMF tones; a plug electrically connected to the converter; and a second housing for supporting the first memory device, the first data entry device, the converter, and the plug; whereby socket assembly receives the second housing such that the plug engages the socket to electrically connect the converter to the telephone device; operation of the switch device causes the converter to generate the electrical DTMF signal based on the sequence of numbers stored by the memory device; and the electrical DTMF signal is transmitted to the telephone device through the plug and the socket.
