Abstract:
A user-operated system for causing a land-line telephone to dial a destination includes a mobile telephony device having a speaker and an internal dual tone multiple frequency (DTMF) dialer, and a dialer extension integrated with a microphone on the land line telephone for capturing a DTMF telephone number sequence. A telephone number is selected on the mobile telephony device, which generates an audible DTMF for the telephone number over the speaker, and the DTMF is captured by the microphone, and the land-line telephone dials the destination.
