    摘要: The present invention is a circuit that is set in a communication apparatus. The circuit is co-operated with a button of an audio receiving/transmitting device for triggering an on-hook or off-hook function when the communication apparatus receives an incoming call. The button is normally closed. The on-hook and off-hook functions are triggered by a triggering signal which is higher than a threshold value. Thus, the present invention doesn't execute the on-hook or off-hook function by an on/off button set in the communication apparatus but directly execute the button set in the audio receiving/transmitting device, which improved the convenience of the communication apparatus.
