In this way, it is possible to answer a call received from the own machine and connect a communication line to the called party to make a call.

When making a call from the mobile phone terminal of this embodiment, for example, by pressing a numeric key provided on the key operation unit 114 of the mobile phone terminal, the intended recipient's phone is called. When a number is input, the pressed numeric key is detected by the press detection unit 113, and the CPU 119 is notified through the control line 101. The CPU 119 temporarily stores this in the RAM 110, for example, and when it detects that the call start key has been pressed, forms a transmission signal including the accepted telephone number and transmits it through the communication circuit 104 and the transmission / reception circuit 103.

This outgoing signal is transmitted to the intended telephone terminal of the other party through facilities on the telephone company side such as a base station and an exchange. Then, when the other party performs a response operation in response to this outgoing signal, a response signal is transmitted from the other party. Therefore, when this response signal is received, the communication circuit 104, under the control of the CPU 119, has its purpose. It is confirmed that the communication line is connected to the other party, and the transmission / reception antenna 103, the communication circuit 104, the D / A converter 10
