Abstract: An apparatus and method are disclosed for connecting a headset microphone alternately to a telephone line and an alternative device. The apparatus includes a device connector for connecting the apparatus to the alternative device, a telephone connector for connecting the apparatus to the telephone line, and a microphone connector for connecting the apparatus to the microphone. The apparatus also includes a switching circuit connected to the device, telephone, and headset connectors. The switching circuit can be used with or included in a CTI module. 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 device connector.
