ABSTRACT:
The present invention is directed to a method and system for detecting a wireless telephone communication in a vehicle, and once detected, when the vehicle exceeds a predefined speed limit, for generating and sending Dual-Tone Multi Frequency (DTMF) encoded information over the voice channel. The encoded information comprises the values of various physical parameters related to the moving vehicle. For instance, these parameters can include the current time at which the telephone communication started, and optionally, the position of the vehicle. In a particular embodiment, the values of the various parameters are sent at regular time intervals until the communication terminates.
