Abstract

The present invention combines the advantages of existing systems such as a small exchange, a fax switch machine, an answering machine, etc., improves the problems, eases installation by miniaturizing and lightening the device, and can be easily used in a general home or a small office. Its purpose is to reduce waste of human resources by speedy call and exchange service and elimination of operator.

In order to achieve the above object, the present invention provides a connection between a microcomputer 10 for controlling the apparatus, a memory circuit 50 for storing voice data used in a program and a voice service of the apparatus, and internal telephones of the apparatus. Internal telephone connection circuit 60, a telephone line connection circuit 70 for connecting a telephone line, and a selection control circuit 40 for allowing the microcomputer 10 to selectively control a specific circuit; It is configured by being connected to the microcomputer monitoring furnace 30 for monitoring whether 10) operates normally and the external selection switch circuit 20 that can operate the microcomputer 10 by an option.

The present invention configured as described above is a telephone answering machine small switch that combines key functions such as a key phone system, an automatic answering machine, a fax switch, and the like. It can be easily installed in small offices and automatically send out voice guidance when a call is made, and if you press the two-digit exchange number, you can call the desired exchange number directly without a call center operator, so you can save fast exchange work and manpower. In addition, it has an inexpensive and economical effect that detects a fax call number and automatically connects it to a fax machine.
