PURPOSE:To execute automatically a reception against a transmitter from a door-phone, even when an incoming side is absent, by connecting a control means for outputting a command for connecting the door-phone and a designated telephone set of the outside, to a main control means, at the time of absence. CONSTITUTION:In case when a visitor comes to a house and the family is absent, when a code for showing the absence and a telephone number of a contact destination are stored in advance in a storage means 14 of a telephone set attachment 1, a call signal from a door-phone 25 is transmitted to a main control means 11. The means 11 operates a channel switch means 7 and outputs a message for waiting for a little while to the door-phone 25. Subsequently, an auto dial means 8 is driven by a control means 15, and the telephone number which has been stored in advance is outputted. Next, the means 15 outputs a command for connecting the door-phone 25 and a telephone set 27 to the means 11 through an incoming side response detecting means 9, and the means 11 operates the means 7 and connects a subscriber's telephone line 5 and a call line 3. In this way, even when an incoming side is absent, an answering can be executed automatically to a transmitter.
