FIG. 1 shows the entire communication system of this embodiment. In this figure, the communication system
It comprises a call center 10, a client terminal 20, an Internet service provider 30, the Internet 40, a subscriber telephone network 50, a subscriber telephone 60, and the like. The client terminal 20 is connected to the Internet 40 via the Internet service provider 30. Usually, a dial-up connection is used by PPP. Of course, the client terminal 20 and the Internet 40 may be connected by a dedicated line. The call center 10
On the one hand, it is connected to the Internet 40 and, on the other hand, at the point of interconnection (POI) 51
Connected to 0. The subscriber telephone set 60 may be a fixed telephone set or a mobile station for mobile communication. Also PDA
And the like.

The call center 10 includes a web server 11, a call server 12, and a gateway 13. The web server 11 stores an HTML document and transmits a desired web page to the client in response to a request from the client. The web server 11 includes functions of an application server such as a CGI (Common Gateway Interface). The call server 12 instructs the gateway 13 to make a call based on the call data sent from the web server 11, receives the IP packetized voice information sent via the Internet 40, and sends it to the gateway 13. And the gateway 13
Is transmitted to the destination client device 20 via the Internet 40.
The gateway 13 converts between an IP packet and a voice signal.

The client terminal 20 is a personal computer, a portable terminal, or a portable telephone. The client terminal 20 has a web browser (browsing client) 2
1. A call client 22 is mounted. The web browser 21 is for using a browsing service provided by the web server 11, and receives a web page to be viewed from the web server 11 and displays the web page. The call client 22 makes a request to the call server 12 of the call center 10 to request the transfer of the IP packetized voice information. The call client 12 converts an audio signal input from a microphone (not shown) of the client terminal 20 into an IP packet. The call client 12 can be realized, for example, as plug-in software of the web browser 11 or a JAVA applet.

FIG. 2 shows a procedure for using the telephone system of this embodiment. In this figure, the user accesses the home page of the telephone service using the web browser 21 of the client terminal 20 (S10). . Thereafter, a user ID and a password are input (S11).
If the input contents are correct, the telephone directory of the user is displayed. FIG. 3 shows a display example of the telephone directory. Clicking on a desired destination in the telephone directory selects the destination. The information on the destination is sent to the telephone server 12 via the web server 11, and a call is made to the destination.

If the user registration of the call service has not been completed, the user registration is performed and a user ID and a password are obtained.

The web server 11 can operate various data by using the application server function. In the figure, telephone directory data 14 of a user is stored. The telephone directory data 14 is managed as a table as shown in FIG. 4, for example. A well-known relational database management system or the like can be used for data management.

FIG. 5 shows the exchange of data in the communication system of this embodiment, focusing on the exchange at the time of calling. First, when you select a destination on the web browser 21,
Destination selection data is sent from the client terminal 20 to the web server (application server) 11. The web server 11 generates destination data (dial data) based on the destination selection data, and sends the destination data to the call server 12. The call server 12 sends destination data and a call request to the gateway 13. The gateway 13 sends a call signal to the destination telephone 60. When the telephone 60 is picked up, a response signal (off-hook) is transmitted from the telephone 60 to the gateway 13 and response information is transmitted to the call server 12. The call server 12 sends the response information to the client terminal 20, and the client terminal 20 is notified that the call is possible. Thereafter, audio information is exchanged between the client terminal (microphone and speaker (not shown)) 20 and the telephone 60.

As described above, according to the communication system of this embodiment, a telephone call can be made using a web browser.

The present invention is not limited to the above-described embodiment, but can be variously modified without departing from the gist of the invention. For example, as shown in FIG. 5, the present invention can be applied to a mobile phone 70 capable of accessing the Internet. For example, the user accesses the Internet using the mobile phone 70 to browse the screen of the call service, selects a destination in the same manner as in the previous embodiment, and selects the call center 10.
Can be used to make calls. In the example shown in FIG. 5, the user can operate the IP button 71 to access the Internet.
