ABSTRACT:
A system and method for communicating electronic messages between a remote device and a messaging server over telephone lines using acoustic coupling. Information is communicated between the remote device and the messaging server using acoustical tones corresponding to the information. The messaging server provides store-and-forward capability for messages received from external sources and which are then forwarded to the remote device. The remote device generates acoustical tones corresponding to information to be transmitted to the messaging server. The acoustical tones are transmitted to the messaging server over a telephone network which is acoustically coupled to the remote device. The messaging server performs processing based on information received from the remote device. The messaging server generates acoustical tones corresponding to information, including messages, to be transmitted to the remote device. These acoustical tones are transmitted by the messaging server over the telephone network and received by the remote device via the acoustic coupling between the remote device and the telephone network.
