Abstract

A telephone terminal has a plurality of handsets and at least one button to input a demand for starting an outgoing call or receiving an incoming call. The terminal includes a demand recognition unit for recognizing the input demand through the one button. The terminal also includes a search unit for searching for handsets in the idle status when the input demand has been recognized. The terminal further includes a select unit for selecting one of the searched handsets that are in the idle status as a selected handset. The terminal also includes a call connection unit for controlling a call connection of the operation corresponding to the input demand, when a handset in the idle status has been selected. The terminal still further includes a nullification unit for nullifying the input demand when no handset in the idle status has been selected.
