Description

The method of Internet telephony service using name that resembles telephone number}

Recently, the era of free telephone service using the Internet is coming. However, these services must pay for free. In other words, you don't want to see propaganda. In addition, to receive customer service, the company needs a C.O.line for customer service calls and a call center to prepare for the call.

The present invention provides a service providing method for allowing an Internet phone user using the Internet to use a customer service call free of charge using the Internet. The Internet is free (of course, you pay for local calls if you use a modem from a home), but the problem is that the agent must use a computer for customer service or a phone line if you use a regular phone. Has the disadvantage of visiting sites such as Dial-pad and seeing propaganda. In addition to providing services such as dial-pad, the system also provides a service that enables a call with an agent who uses a number of landline telephones on one Internet line by using the VOIP gateway for SOHO (Small or Home Office). have.

The present invention is based on the VOIP technology that allows voice to be transmitted between the Internet telephone terminal or the Internet telephone terminal and the existing telephone network terminal by transmitting voice on the Internet, thereby enabling effective connection service between them.

The technical background of the present invention is as follows.

The service scenario of PC-to-Phone type that is generally being serviced is as follows. First, visit the homepage that provides the service and press the call request button.

Internet phone client program is running. The user clicks the call partner on the web, or the Internet phone client program receives a telephone number from the user. The Internet phone client program receives the IP address information of the VOIP gateway from the server and attempts to connect to the VOIP gateway using the IP address information.

When the connection is complete, a phone call is made between the Internet phone and the VOIP gateway.

Here, among the VOIP gateways distributed according to the telephone number of the telephone network to be accessed, the allocation may be performed according to local information or busy information.

In a typical PC to PC service scenario, the IP address of the receiving terminal is known first, and a corresponding IP address is directly inputted.

In the above case, if the VOIP gateway is a phone that does not have a personal or special telephone network telephone number or is a pure Internet phone terminal, it is very cumbersome to enter the IP address of the other terminal directly from the Internet telephone terminal. Do. Therefore, there is a need for a solution.

Therefore, in the present invention, a telephone number is input from a user to connect an Internet telephone terminal or a VOIP gateway from an Internet telephone terminal device, and a number translation device and subscriber information for finding the IP address of the Internet telephone terminal and the VOIP gateway from the telephone number. It consists of a call center that allows users to easily register and search for subscribers, and registers a subscriber's telephone number equipped with a VOIP gateway using an existing telephone number.

The following shows the process of automatically registering a user in the process of installing an Internet phone terminal or VOIP gateway.

A user with a PC goes through the process of installing a program that performs the necessary client functions when he wants to receive Internet phone service. To do this, the user first visits a service center using a web browser and performs a user registration procedure.

For general users

Fill out the User Information Form, submit it, and have the user ID and password registered. At this time, duplicate user ID is excluded. After that, the client program is downloaded from the management server, and the process is terminated by installing the downloaded client program on the user's PC. After that, the Internet phone service will be used.

For VOIP Gateway Users

When the user inputs and submits the user information through the web, the contents input by the person and the contents set by the system are transmitted to the service center. In the information input by human, alias information of installed VOIP gateway is recorded, and the information of system is sent to service center.

6 shows a procedure for the occasional registration of an Internet telephone terminal or VOIP gateway using a variable IP. When a modem is used by a company or home user who has not been assigned a fixed IP address, the IP address of an Internet telephone terminal or a VoIP gateway is changed.

When the internet phone terminal is turned on or the internet phone terminal program is turned on, the registration procedure is performed at the service center (or address translation device) including the internal information, and the IP address of the internet phone terminal is checked. . If there is a change by checking the IP address of the Internet phone, the change is recorded in the address translator and the address conversion device is recorded that the corresponding Internet phone is activated.
