Hereinafter, the present invention will be described in detail with reference to the accompanying drawings.

1 is a block diagram of a conventional Internet telephone, showing a general computer device versus a public telephone network. The Internet phone user having the computer device 20 uses the mouse 10 to connect the microphone 40 and the speaker 50 to the sound card 30 of the computer device in which the communication program for the Internet phone is embedded. Enter a phone number in the dial pad on the screen to dial. The modem / LAN card 60 of the computer device transmits the dialing information to the server 80 and the gateway 90 via the Internet 7, and the server 80 and the gateway 90 based on the received dialing information. By completing the call setup with the general telephone 110 connected to the public telephone network 100 so that the user of the computer device and the user of the ordinary telephone can make a telephone call over the Internet.

2 is a diagram illustrating the configuration of an Internet phone according to the present invention, in which a converter 130 is added between the general telephone 120 and the computer device 140. The conversion device 130 has a normal telephone mode and an internet telephone mode, and the general telephone mode allows a general telephone 120 to be connected to a public telephone network 200 so as to make a telephone call with another ordinary telephone 210. Mode, and the Internet phone mode is a mode in which the ordinary telephone 130 is connected to the computer device 140 connected to the Internet 170 by a modem / LAN card 160 to make an Internet telephone call with another ordinary telephone 210. to be. In the normal case, the conversion device 130 is in a normal phone mode, and the Internet phone mode of the conversion device 130 is a case where the conversion device 130 receives a signal for an internet phone by a function button of the general phone.

3 is a block diagram of a conversion device devised by the present invention. The conversion device of the present invention includes a control unit 242, an indicator light 243, an ASCII code transmission line 244, a switch 246, and a signal converter 248. Consists of. In the normal case, the conversion device 130 connects the ordinary telephone 220 to the public telephone network 300 using the transmission line 282 and the reception line 284 by the control unit 242 and the switch 246. There is a state of a general telephone mode that allows a telephone call with a regular telephone 310, which can be seen through an indicator 243 showing a color defined as a normal telephone mode. When the control unit 242 of the conversion device receives the signal promised in the Internet phone mode by the function button of the normal phone 220, the control unit 242 of the conversion device is controlled by the keypad of the normal phone 220. Converts the received dialing information into an ASCII code and then transmits the dialing information to the computer device 250 via an ASCII code transmission line 244 connected to the serial port 252 of the computer device. This is indicated by the light 243 which shows the color promised in the telephone mode. The computer device 250 incorporating a communication program designed for an Internet phone call using the conversion device 240 may receive the received Internet phone dialing information from a server 270 connected to the Internet 260 through a modem / LAN card 258. The gateway 290 establishes a call with another general telephone 310 connected to the public telephone network 300. After the call setup is completed, the control unit 242 of the conversion device connects the transmission line 225 and the reception line 230 of the ordinary telephone to the signal converter 248 using the switch 246 of the conversion device. 248 converts the transmission signal and the reception signal of the ordinary telephone to the sound card 254 signal of the computer device and transmits the sound signal to the sound card 254 so that an internet telephone can be made.

4 is a flowchart of the operation of the present invention. Operation start (S10) of the present invention is the first step (S20) of installing a communication program designed for the conversion device in the computer device. The program installed by the first step resides in the RAM of the computer device and is in a state of the second step S30 where the signal of the conversion device can always be received while the computer device is powered on. From the second step, the computer device becomes a third step (S40) in which the conversion signal is turned on to receive an ON signal of the conversion device and make an Internet phone call. The converter is in the state of the fourth step S50 that has received the dialing information due to the keypad of the ordinary telephone. From the fourth step, the control unit 242 of the conversion device performs a fifth step S60 of determining whether the received dialing information is for an Internet phone. In the fifth step, the control unit 242 of the conversion apparatus determines the received dialing information, and when the dialing information is for general telephones, connects the ordinary telephone 220 to the public telephone network 300 and displays a color corresponding to the normal telephone mode. Perform the sixth step shown in. When the control unit 242 of the conversion device receives the dialing information for the Internet telephone by the function button of the ordinary telephone, the indicator 243 makes the color of the Internet telephone mode appear, and then the received dialing information is stored in the ASCII code transmission line. By transmitting to serial port 252 of the computer device via 244, the computer device executes a seventh step S70 of processing the dialing information received from the serial port 252. The computer apparatus performs an eighth step S80 of performing an internet phone call. The computer apparatus that has performed the eighth step sets up the call of the Internet telephone, and the switch 246 of the converter connects the signal of the transmission line 225 and the receiver line 230 of the ordinary telephone to the signal converter 248 of the converter. The signal converter 248 of the conversion device converts the transmission signal of the ordinary telephone 220 received through the transmission line 225 into the sound card 254 of the computer device, and then the sound card 254 of the computer device. To send. Then, the call signal received from the other general telephone 310 on which the call of the Internet telephone is set is received by the signal converter 248 of the converter through the sound card of the computer device, converts the signal corresponding to the general telephone, and then receives the reception line 230. The ninth step (S90) is transmitted to the general telephone 220 through which the general telephone is transmitted and received via the Internet. When the telephone disconnection signal of the telephone is transmitted to the computer device after the telephone call is made between the ordinary telephones through the Internet of the ninth stage, the computer apparatus executes the tenth step S100 of performing the telephone disconnection. After executing the tenth step of hanging up, the computer device performs the eleventh step (S110) in a standby state.

With the conversion device and the program of the present invention, a telephone user can selectively use a public telephone network and an internet telephone network as a general telephone, so that there is no need for a separate Internet terminal for making an Internet telephone call. When the converter of the present invention is added to the fixed device of the cordless telephone and the serial port of the computer device, the telephone user can receive mobile Internet telephone service by the portable device of the cordless telephone.
