A control unit 1A that transmits dial signals, controls incoming and outgoing calls, etc., and a communication unit 3 that performs 2-wire/4-wire conversion etc. are connected to the terminal. An operation unit 2A having a numeric keypad, tone adjustment keys, etc. is connected to the control unit 1A. The dialing signal is sent out in the same way as in the past, but when the sound quality adjustment key of the operation unit 2A is operated, the control unit 2A controls the voice generated from the receiver R of the handset 4 based on the data of this key operation. A sound quality control signal indicating what kind of change is to be caused in the frequency component of is sent to the sound quality adjustment section 6. In this way, the operation section 2A and the control section 1A constitute the sound quality control signal sending means 20. The sound quality adjustment section 6 is sent from the other party to the line 10.
．． The frequency characteristics of the audio signal arriving via the communication section 3,
It outputs a change based on a sound quality control signal, and is composed of, for example, a filter or an addition/subtraction circuit, and changes the sound quality by strengthening or weakening a desired frequency component.
