Abstract
A hands-free apparatus determines whether there is an incoming call, and then determines whether the incoming call is to be answered by switching from a current call or to be rejected. When the incoming call is determined to be answered, the current call in a hands-free communication is put on hold for switching to the incoming call, and call partner information of the current call is spared from being displayed on a display unit to represent that the incoming call is now being established.
