In an automatic telephone call transfer apparatus in an Internet connection mode, an initial value setting portion sets a telephone number of an exchange of a telephone office which will perform a call transfer, a telephone number of an ISP to be subject to the call transfer, and an automatic/manual mode. An automatic call transfer setting/canceling portion transmits data corresponding to the telephone number of an exchange of a telephone office set at the initial value setting portion, call transfer request data, and the telephone number of the ISP to be subject to the call transfer at the connection of an Internet service, and at the termination of the Internet service, transmits the number of the exchange of the telephone number set at the initial value setting portion and data for canceling the call transfer. A modem is connected to a communication line. A telephone connection portion makes a telephone call at the telephone number of the exchange of the telephone office received at the connection and termination of the Internet. A first switch is connected to the telephone connection portion at the connection and termination of the Internet to transmit the data from the automatic call transfer setting/canceling portion to the exchange of the telephone office through a network and then connects to the modem. A voice conversion portion converts analog voice signals to digital signals to perform modulation and compresses and converts the signals into packet data when the voice signals are transmitted, and restores the packet data into analog signals when the voice signal is received. A second switch is connected a telephone to the voice conversion portion in the Internet connection mode and to telephone connection portion in the other mode.
