Abstract

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.

Claims

1. An automatic telephone call transfer apparatus in an internet connection mode, comprising:

an initial value setting portion which sets a telephone number of an exchange of a telephone office which performs a call transfer, a telephone number of an Internet Service Provider (ISP) subject to said call transfer, and an automatic/manual mode;

an automatic call transfer setting/canceling portion which outputs data corresponding to said telephone number of said exchange of said telephone office set at said initial value setting portion, call transfer request data, and said telephone number of said ISP subject to said call transfer upon connection to an Internet service, and at termination of the Internet service, outputs said telephone number of said exchange set at said initial value setting portion and data for canceling said call transfer;

a modem connected to a communication line;

a telephone connection portion which calls said telephone number of said exchange of said telephone office received at connection and termination of the Internet service;

a first switch, connected between said modem and said telephone connection portion, wherein at the connection and termination of the Internet service, said first switch transmits said data output from said automatic call transfer setting/canceling portion to said exchange of said telephone office;

a voice conversion portion which converts analog voice signals to digital signals, compresses said digital signals, and converts compressed signals into packet data when voice signals are transmitted, and restores received packet data into analog signals when a voice signal is received; and

a second switch which connects a telephone to said voice conversion portion in the Internet connection mode, and which connects said telephone to said telephone connection portion in a telephone connection mode.

2. A method for setting an automatic telephone call transfer in an Internet connection mode, comprising:

setting an initial value for a telephone number of an exchange of a telephone office which performs a call transfer, a telephone number of an Internet Service Provider (ISP) subject to said call transfer, and an automatic/manual mode;

converting said Internet connection mode to a telephone connection mode when said automatic/manual mode is set to an automatic mode;

requesting a call transfer by calling said telephone number of said exchange of said telephone office;

transmitting call transfer data for transmitting data on said telephone number of said ISP after completion of a call transfer request; and

converting said telephone connection mode to said Internet connection mode after completion of said call transfer transmitting step.

3. A method for canceling an automatic telephone call transfer in an Internet connection mode in a system in which a call transfer is automatically performed by using a telephone number of an exchange of a telephone office which performs a call transfer and a telephone number of an Internet Service Provider (ISP) subject to said call transfer, said method comprising:

determining whether Internet service is terminated;

converting said Internet connection mode to a telephone connection mode when the Internet service is terminated; and

transmitting data for requesting said call transfer by calling said exchange of said telephone office in said telephone connection mode.

4. An automatic telephone call transfer apparatus in an internet connection mode, comprising:

an automatic call transfer setting/canceling portion which outputs data corresponding to a telephone number of an exchange of a telephone office which performs call transfer, call transfer request data, and a telephone number of an Internet Service Provider (ISP) subject to said call transfer upon connection to an Internet service, and at termination of the Internet service, outputs said telephone number of said exchange and data for canceling said call transfer;

a modem connected to a communication line;

a telephone connection portion which calls said telephone number of said exchange of said telephone office received at connection and termination of the Internet service; and

a first switch, connected between said modem and said telephone connection portion, wherein at the connection and termination of the Internet service said first switch transmits said data from said automatic call transfer setting/canceling portion to said exchange of said telephone office.

5. A method for setting an automatic telephone call transfer in an Internet connection mode, comprising:

requesting a call transfer by calling a telephone number of an exchange of a telephone office which performs said call transfer;

transmitting call transfer data on a telephone number of an Internet service provider after completion of a call transfer request; and

converting a telephone connection mode to said Internet connection mode after completion of said call transfer transmitting step.
