However, in the related art, even when using a web phone, a user using a regular phone cannot make a call to the other phone through the Internet, and cannot receive an incoming call through the Internet through a general phone connected to a public telephone network. there was.

For this reason, there is a problem that even a user who uses an Internet phone having a low cost advantage cannot use the Internet phone when the receiver uses a regular phone. There was a problem.

Accordingly, the present invention for solving the above problems is a relay device having a first port connected to the Internet and a second port connected to the public telephone network, comprising: means for detecting a call from the first port, and a telephone through the Internet Means to dial a called telephone number connected to a public telephone network, which is stored in advance when a call is received, a means for detecting a telephone call from a second port, and a call message sent to a second port to send a message to the receiving telephone number. And means for inputting, and means for dialing and inputting the input telephone number to the first port, so that a user can receive a call from the Internet to a regular telephone connected to a public telephone network. You can make a call to the other phone connected to the internet network. And the relay transmission and reception of telephone calls using the Internet and telephone network that allows to send and receive low-cost international calls and long distance telephone calls for the purpose of providing a half.

Hereinafter, preferred embodiments of the present invention will be described with reference to the accompanying drawings, FIGS. 1 to 4.

The relay device 30 of the present invention for achieving the above object,

Key part consisting of a first port 10 connected to the Internet via a PC 23, a second port 11 connected to a public telephone network (PSTN), and a plurality of keys for entering a phone number and function (13), a handset 14 for a call, and a display section 16 for outputting a key input state,

An input / output unit 12 for inputting / outputting an electric signal through the first port 10 and the second port 11;

A memory 15 for storing a called number;

A first ring detector (17) for detecting a ring signal input through the first port (10);

A control unit 22 for controlling dialing to a called number stored in the memory 15 when the first ring detection unit 17 detects a call received through the Internet;

And a dialing unit 12 for dialing a phone number stored in the memory 15 through the second port 11 under the control of the control unit 22.

It is characterized in that the user can receive a call received through the Internet to the general telephone 24 connected to the public telephone network.

And a second ring detection unit 18 for detecting a ring signal of the telephone 24 coming into the second port 11;

When the ring signal is detected by the second ring detection unit 18, the voice message output unit 20 further outputs a predetermined guide message stored in advance to the transmitting side to induce the input of a desired telephone number. Make up,

The control unit 22 drives the dialing unit 21 to dial the telephone number input from the transmitting side so that dialing information is transmitted to the Internet through the first port 10 so that the user of the telephone 24 can access the Internet network. It is characterized in that through the call with the other party.

Reference numeral 23 that is not described indicates a PC to which the first port 10 of the relay device 30 is connected, and the PC 23 is connected to the Internet so that an Internet phone can be made.

Referring to the operation of the present invention configured as described above is as follows.

◆ Call Forwarding ◆

Incoming function is a function used when the user wants to receive a call from the Internet to the telephone 24 connected to the public telephone network, and for this purpose, the user receives the incoming telephone number (public) in the memory 15 of the relay device 30. Save the telephone number of the telephone connected to the telephone network.

In this state, when a call is made to the relay device 30 through the Internet, the first ring detector 17 of the relay device 30 detects a ring signal of the call coming to the first port 10 and controls the control unit 22. When the ring signal is detected at the first port 10, the controller 22 drives the dialing unit 21 to dial an incoming telephone number stored in the memory 15.

Accordingly, the dialing unit 21 dials the called number stored in the memory 15 and transmits the incoming number to the second port 11 through the input / output unit 12, and when the user receives the telephone 24, the control unit 22 ) Connects the incoming call to the first port 10 to the telephone 24 through the input / output unit 12 and the second port 11 so that the user is connected to the public telephone network (PSTN). It can be received by the telephone 24.

The incoming call function as described above is dialed directly to the called number when a call is made to the first port 10 by the input of a separate incoming call function key provided in the key part 13, and the user dials the call to the Internet as the telephone 24. The user may not receive the handset 14 even though a certain number of times rings at the relay device 30 by the call to the first port 10 as another side. You can automatically switch to the incoming call when.

◆ Send function ◆

The transmission function is a function that allows a user to make a phone call to another user who uses an Internet phone by using a telephone 24 connected to a public telephone network.

First, the user makes a call to the relay device 30 using the telephone 24.

Accordingly, the ring signal is input to the second port 11 of the relay device 30, and the second ring detector 18 detects the ring signal input to the second port 11 and outputs the ring signal to the controller 22. In addition, the controller 22 drives the voice message output unit 20 so that a guide message for inducing the input of the receiving telephone number is sent.

In other words, the voice message output unit 20 is a pre-stored message "Enter the phone number to connect" under the control of the control unit 22 to the phone 24 through the second port 11 The user who listens to the announcement message enters a key provided in the telephone 24 to input a desired telephone number.

When the receiving telephone number is input from the telephone 24, the control unit 22 drives the dialing unit 21 so that the input telephone number is dialed, and the dialing unit 21 controls the control of the control unit 22. The dialed telephone number is dialed and transmitted through the first port 10.

By the dialing operation of the dialing unit 21, a call signal is transmitted to the telephone of the receiver connected to the Internet, and when the receiver receives a telephone call, the user of the telephone 24 connected to the public telephone network connects a low-cost Internet telephone. You can easily talk to the user you are using.

The use of the relay device 30 of the present invention as described above has the advantage that a user using a general telephone connected to a public telephone network can use international calls, long distance calls, etc. using low-cost Internet calls. In addition, it is possible to receive a call from the Internet to the telephone 24 connected to the public telephone network, and furthermore, by setting the called phone number to his own mobile phone so that the user can receive a call from the Internet without regard to the place. do.

As described above, the present invention relates to a relay apparatus having a first port connected to the Internet and a second port connected to a public telephone network, comprising: means for detecting a call from the first port; Means for dialing an incoming telephone number connected to a public telephone network, which is stored in advance, means for detecting a call from a second port, and a call message sent to a second port for inputting a receiving telephone number. And means for dialing an input telephone number to a first port so that a user can receive a telephone call from the Internet to a regular telephone connected to a public telephone network. You can make calls to the other phone connected through the network. So you can send and receive standing low cost international calls and long distance calls can be expected to have the effect of providing a relay device that enables the sending and receiving Internet phone using the telephone and the telephone network.
