A real-time audio to data and data to audio converter for use in transmitting an audio converted to data signal, typically a telephone conversation, over a data transport system, such as the Internet. The converter is hardware and thereby eliminates delays inherent in a software converter and eliminates the need for computer calculation . The converter is positioned at the access site of a data transport system and comprises a telephone interface for linking telephone lines to the converter. The telephone interface is attached to a transmitter and a receiver, whereby the telephone interface receives audio signals and transmits the audio signal to a real-time converter. The real-time converter converts the audio signal received from the telephone interface to a data signal, the data signal is transmitted by the transmitter to a data transport system. The receiver receives the data signals from the data transport system, sends the data signals to the converter, whereby the data signals are converted back to audio signals to be routed to the recipient as audio signals. A method for converting audio signal to data signals and data signals to audio signals in real time is also disclosed.
