A handset module (10) forms a remote unit in combination with the handset (12) and has a casing (14) with circuit means (fig. 3) in the casing (10). The circuit means (fig. 3) includes a transmitting portion (78) and a receiving portion (80) for audio signals. A means (70) electrically connects the transmitting portion (78) of the circuit means (fig. 3) to a microphone in the telephone handset (12). The electrical connection means (70) also connects the receiving portion (80) of the circuit means (fig. 3) to a headphone of the handset (12). The handset module (10) also includes a means (22) for fastening the casing (14) to the handset (12). A console module (150) forms a base unit of the system in combination with the console (152). The console module (150) incorporates transmitting and receiving circuits (182, 184) and couplers (180) for supplying and receving signals from the console (152).
