An apparatus and method are disclosed for connecting a headset alternately to a telephone line and an audio device. The apparatus includes an audio connector for connecting the apparatus to the audio device, a telephone connector for connecting the apparatus to the telephone line, and a headset connector for connecting the apparatus to the headset. The apparatus also includes a switching circuit connected to the audio, telephone and headset connectors. The switching circuit connects the telephone connector to the headset connector in response to sensing a voltage greater than a predetermined threshold on the telephone line. When the voltage sensed returns to a value less than the predetermined threshold value, the switching circuit reconnects the headset connector to the audio connector.
