CONSTITUTION: A signal analyzing unit(120) analyzes a number input signal and a call signal generated according to the pushed degree of a hook button of an ear microphone. A signal processing unit(130) detects a number key corresponding to the number input signal analyzed in the signal analyzing unit(120), and stores the detected number key in a memory unit(160). A control unit(140) receives the signals of the signal analyzing unit(120) and the signal processing unit(130), and performs a call connection.
