Abstract

A telephone system for a motor vehicle includes a transmit/receive unit that transmits data over a wireless communication channel, and receives data over the wireless communication channel and provides a received signal. The system also includes a control unit that communicates with the transmit/receive unit; a first memory device; and a computing device. The computing device receives the received signal and automatically stores the received signal data in the first memory device when the telephone system is configured in a stand-by mode, which allows incoming data to be stored in the memory device while selectively preventing the transmission of outgoing calls originated by the control unit to the transmit/receive unit. Data can be sent to the motor vehicle telephone system and can be stored there for retrieval by the operator when he returns to the vehicle. The data may include audio and/or video data.
