ABSTRACT:
A telephone set provided with a telephone ringer for producing a ringing sound, a telephone number storing device for storing a telephone number of a specific party in response to a registration operation performed by a user, a telephone number detecting device for detecting telephone number data input from a telephone line and a control device for controlling and causing the ringer to produce a ringing sound when a telephone number indicated by the telephone number detected by the telephone number detecting device matches the telephone number stored in the telephone number storing device. Thereby, when the specific party phones the user, the user can easily know this. For example, if the user is going to concentrate his mind upon his work, or if the user is immersed in his work at a distance from the telephone set, the user can readily know whether or not a caller is the specific party, the telephone number of which is registered in the telephone set. Consequently, the telephone set can prevent the user from making an unnecessary response to a call given by a calling party other than the specific party.
