The above objects and various advantages of the present invention will become more apparent from the preferred embodiments of the invention described below with reference to the accompanying drawings by those skilled in the art.

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

2 is a block diagram of an IP voice terminal having an Internet fax function according to the present invention. The IP voice terminal connected to the general facsimile 100 includes a microphone 110, a switch unit 120, and a subscriber line connection circuit 130. ), A voice codec 140, a controller 150, and a LAN interface 160.

In such a configuration, the general facsimile machine 100 is a device capable of transmitting and receiving fax documents through a public telephone network, and the subscriber line access circuit 130 is connected to the general facsimile machine 100 to connect subscriber lines. Perform connections and interfaces.

The switch unit 120 alternately switches the microphone 110 (or a speaker, not shown) and the subscriber line connection circuit 130, which are voice transmission means of the IP voice terminal, based on a user's switching operation. The voice codec 140 is connected.

In addition, the speech codec 140 converts an analog voice or fax signal applied from the switch unit 120 into a digital voice or fax signal, and converts the digital voice or fax signal applied from the controller 150 to be described later. Two-way voice modulation and demodulation is performed by converting the voice signal to the subscriber line connection circuit 130 through the switch unit 120.

On the other hand, the controller 150 is a means for controlling the Internet network access, exchanges digital voice and fax signals in both directions with the voice codec 140, and controls the connection and interfacing with the Internet network.

In addition, the LAN interface 160 performs data exchange between the controller 150 and the Internet network by performing an access and interfacing with the Internet network.

Next, an operation process of the IP voice terminal having the Internet fax function according to the present invention having the above-described configuration will be described in detail.

First, in order for a user to make a voice call through the Internet network, the LAN interface 160 controls the Internet through the Internet network under the control of the control unit 150 through a predetermined access procedure such as input of a phone number corresponding to the other party's address. Attempt to connect with the other subscriber, it is possible to perform voice transmission and reception with the other subscriber via the microphone 110 and the speaker not shown in the connected state.

That is, the analog voice signal applied from the microphone 110 is applied to the voice codec 140 through the switch unit 120, and the voice codec 140 modulates the applied analog voice signal into a digital voice signal to control the controller 150. The digital voice signal applied to the control unit 150 is transmitted to the counterpart subscriber via the Internet server performing voice service through the Internet network, that is, the Internet network in the LAN interface 160.
