てなる電話装置。 In a telephone device equipped with an automatic call/receive function that transmits a dial signal corresponding to a pre-stored dial number of the other party to the other party, and then detects a response from the other party and becomes ready to make a call, the dial signal to the other party is transmitted to the other party. A control means for generating and outputting a control signal at the time of transmission and when detecting a response from the other party, a load having an impedance value approximately equal to that of the handset, and a control means for transmitting a control signal to the other party according to the control signal supplied from the control means. While transmitting a dial signal, the load is connected to the call line and the handset is electrically disconnected from the call line, and after a response is detected from the other party, the load is disconnected from the call line, and the handset is disconnected from the call line. 1. A telephone device comprising switching means for connecting to a telephone.
