In FIG. 1, a PC 100 used by a user of a telephone call, a call server 200 for realizing a call between the PC 100 and the telephone terminal 300, a telephone terminal 300 used by an operator of a telephone call destination, 2 shows an Internet 400 that connects a PC 100, a call server 200, and a telephone terminal 300 to each other.

  The telephone system shown in FIG. 1 is typically used when a user who is a purchaser of a product through so-called Internet shopping is used by the user and the telephone terminal 300 is used by a store clerk at a so-called Internet shopping store. be able to. In the case of such use, it becomes possible to make an inquiry to a store clerk by telephone using the call system of the present embodiment regarding a product that the user is considering purchasing.

The PC 100 needs to have at least a web browser installed. The PC 100 can download a web page stored in the call server 200 by starting a web browser. This web page is typically a web page managed at a store or the like for Internet mail order. The pop-up page is associated with a destination telephone number (including an extension number added) assigned to the telephone terminal 300. The PC 100 is an example, and a PDA (Personal
It is also possible to use a medium that has a web browser installed and can be connected to the Internet 400, such as Digital Assistant).

  The call server 200 calls the telephone terminal 300 in response to a request from the PC 100, and calls the PC 100 in response to a response from the telephone terminal 300. The call server 200 stores a plurality of the web pages and pop-up pages described above.

The telephone terminal 300 makes a call with the user of the PC 100 by receiving a call from the call server 200. The telephone terminal 300 is a VoIP compatible telephone terminal. The Internet protocol is SIP (Session
Initiation Protocol), H.I. Any of 323, IPv4, IPv6, etc. may be adopted.

  The Internet 400 mainly connects the PC 100 and the telephone terminal 300 in a so-called extension environment. The Internet 400 transmits and receives data packets corresponding to audio signals between the PC 100 and the telephone terminal 300.

  2 and 3 are diagrams showing examples of web pages stored in the call server 200 of FIG. 1 and examples of pop-up pages linked to the web pages.

  In FIG. 2, a display area 10 such as a store name, a display area 12 of product names of various sales target products, an image area 14 of each sales target product, and a link area 16 for making a download request for a pop-up page. It shows.

  When the user moves the mouse cursor to the link area 16 and selects the link area 16 by clicking or the like, the URL assigned to the pop-up page shown in FIG. The page is downloaded to the PC 100.

  FIG. 3 shows a display area 20 that displays whether or not a call can be made, a call button area 22 that is pressed when a telephone number assigned to the telephone terminal 300 is called, and a disconnect button that is pressed when the call is terminated. An area 24, a speaker volume setting area 26, and a microphone volume setting area 28 are shown.

  The call button area 22 is associated with the destination telephone number assigned to the telephone terminal 300. For this reason, when pressing of the call button area 22 is detected, it is possible to transmit the destination telephone number assigned to the telephone terminal 3000 to the call server 200 as will be described later.

  When a user wants to make an inquiry about a product or the like to a store, as an example, a headset including a microphone and a speaker is connected to the PC 100, a mouse cursor is placed on the call button area 22, and a call button is clicked. When the area 22 is selected, a call between the PC 100 and the telephone terminal 300 is started by a procedure described later. Then, the call volume may be set through the volume setting areas 26 and 28 as appropriate, and the call may be made.

  Thereafter, when the inquiry is completed, the user moves the mouse cursor to the disconnect button area 24 and selects the disconnect button area 24 by clicking or the like, so that the dial connection is released and the call ends.

  FIG. 4 is a diagram showing an operation example of the call system shown in FIG. When the web page and the pop-up page shown in FIGS. 2 and 3 are stored in the call server 200, when the user accesses the call server 200 by operating the PC 100 (step S1), it is shown in FIG. The web page is downloaded to the PC 100 and displayed on the display (step S2).

  Subsequently, when the user clicks the link area 16 in the web page shown in FIG. 2 with a mouse, a script or the like is executed, and the URL of the pop-up page shown in FIG. 3 is uploaded to the call server 200 (step S3). As a result, the pop-up page shown in FIG. 3 is downloaded from the call server 200 and displayed on the display of the PC 100 (step S4).

  Thereafter, when the user clicks the call button area 22 shown in FIG. 3, the PC 100 reads out an identification number such as a MAC address uniquely assigned to the PC 100 at the time of manufacture by using middleware or the like, and passes through the Internet 400. Then, the call is sent to the call server 200 together with the desired telephone number and the destination telephone number assigned to the telephone terminal 3000 (step S5).

  As a result, the call server 200 receives the incoming telephone number, the identification number, and the destination telephone number assigned to the telephone terminal 3000. Note that the telephone number desired to be received corresponds to, for example, a telephone number assigned to a caller or a fixed telephone set in the office, a telephone number assigned to a mobile phone owned by the caller, or the like.

  The call server 200 stores the desired telephone number and identification number transmitted from the PC 100 in a built-in database (step S6). Next, the call server 200 filters the telephone numbers desired to be received (step S7).

For filtering here, when the sender number is included in the header of the data transmitted from the PC 100, the character string of the sender number part is removed, or any character string, etc. In this way, the call server 200 selectively notifies the identification number without notifying the desired telephone number, and calls the destination telephone number of the telephone terminal 300 via the Internet 400. (Step S8).

  That is, in the case of the present embodiment, the call server 200 functions as a gateway that connects the PC 100 and the telephone terminal 300 and blocks a telephone number desired to be received. When the telephone terminal 300 receives the call, the connection between the PC 100 and the telephone terminal 300 is established, and a VoIP call is possible between the PC 100 and the telephone terminal 300 (step S9).

  Here, in step S7, when the identification number is notified from the call server 200 to the telephone terminal 300, for example, the telephone terminal 300 can make a call to the telephone number desired to be received according to the PC 100 at a later date.

  That is, in the call server 200, a pair of the identification number and the desired telephone number for the PC 100 is registered in the database. Therefore, when the identification number is transmitted from the telephone terminal 300, the call server 200 can read out the telephone number desired to be received corresponding to the identification number and make a call.

  For this reason, for example, in the above-described example, the user of the PC 100 inquires about the product etc. to the store where the telephone terminal 300 is installed. At that time, the operator of the telephone terminal 300 makes an inquiry. Even if the answer cannot be made immediately, the operator of the telephone terminal 300 can answer the inquiry to the user of the PC 100 at a later date. Moreover, even in this case, the user of the PC 100 does not know the telephone number desired to be received by the operator of the telephone terminal 300 or the like.

  Note that it is not essential that the identification number is read and transmitted by the middleware of the PC 100. For example, in step S <b> 5, the PC 100 transmits the telephone number desired to be received and the destination telephone number assigned to the telephone terminal 3000 to the call server 200 via the Internet 400 by middleware or the like.

  When the call server 200 receives the desired telephone number transmitted from the PC 100, the call server 200 generates a unique identification number by generating a random number or the like. The call server 200 stores the generated identification number in a built-in database as a pair with the desired telephone number transmitted from the PC 100, and the call server 200 stores the destination telephone number of the telephone terminal 300 as an incoming call request. If the identification number is selectively notified and the call is made via the Internet 400 without notifying the telephone number, the call between the PC 100 and the telephone terminal 300 can be made as described above.

  The description that it is not essential to read and transmit the identification number by the middleware of the PC 100 is the same in the call system according to the second embodiment to be described later.

The telephone terminal 300 may be a general telephone (fixed telephone) or a mobile phone. In such a case, the call server 200 is connected to the Internet 400 and a public switched telephone network (PSTN).
By connecting to both the Switched Telephone Network), the telephone terminal 300 connected to the PSTN and the PC 100 connected to the Internet 400 can be connected.

Of course, instead of the mobile phone terminal 600, a fixed telephone can be adopted.

  The telephone system shown in FIG. 5 is suitable for a case where a telephone number is typically transmitted from the telephone terminal 300 to the mobile phone terminal 600 by transmitting the telephone number of the mobile phone terminal 600 from the PC 100. Can be used. In such a use, the user does not make a call with a telephone charge, or does not make a collect call or toll-free call. In addition, since the Internet 400 is used, it is possible to reduce telephone charges accordingly.

  FIG. 6 is a diagram showing an example of a pop-up page used instead of FIG. FIG. 6 shows a radio button 30 for selecting whether the callback is desired immediately / reserving the callback time, and a pull-down menu 32 for selecting the desired date and time zone when the callback time is reserved. A telephone number input area 34 assigned to the telephone terminal to be called back, a check box 36 for selecting whether or not the telephone number input in the input area 34 is stored, and a telephone input in the input area 34 A send button area 38 for sending a number to the call server 200 is shown.

  The send button area 38 is linked to the destination telephone number assigned to the telephone terminal 300. For this reason, when pressing of the transmission button area 38 is detected, it is possible to transmit the destination telephone number assigned to the telephone terminal 3000 to the call server 200 as will be described later.

  FIG. 7 is a diagram illustrating an operation example of the call system illustrated in FIG. When the web page and the pop-up page shown in FIGS. 2 and 6 are stored in the call server 200 and the user accesses the call server 200 by operating the PC 100 (step S11), the web page and pop-up page shown in FIG. The web page is downloaded to the PC 100 and displayed on the display (step S12).

  Next, when the user clicks the link area 16 in the web page shown in FIG. 2 with a mouse, a script or the like is executed, and the URL of the pop-up page shown in FIG. 6 is uploaded to the call server 200 (step S13). As a result, the pop-up page shown in FIG. 6 is downloaded from the call server 200 and displayed on the display of the PC 100 (step S14).

  Thereafter, the user selects, for example, by clicking the radio button 30 corresponding to “I want a callback now” shown in FIG. 6, and further selects the telephone number assigned to the mobile phone terminal 600 from the keyboard. It is assumed that an input is made in the input area 34 by an operation or the like and the transmission button area 38 is clicked and selected.

  Then, the PC 100 reads an identification number such as a MAC address uniquely assigned to the PC 100 at the time of manufacture, together with the telephone number input in the input area 34 and the destination telephone number assigned to the telephone terminal 3000. Then, it is transmitted to the call server 200 via the Internet 400 (step S15).

  As a result, the call server 200 receives the desired telephone number, the identification number, and the destination telephone number assigned to the telephone terminal 3000, which are input in the input area 34.

  The call server 200 stores the desired telephone number and identification number transmitted from the PC 100 in a database built in a pair (step S16). Next, the call server 200 filters the telephone numbers desired to be received (step S71). In this way, the call server 200 selectively notifies the identification number without notifying the telephone number desired to be received, without notifying the telephone number input in the input area 34, and making a call via the Internet 400. The destination telephone number of the terminal 300 is called (step S18).

  In contrast, when the telephone terminal 300 receives the call, the telephone terminal 300 and the call server 200 are connected. Subsequently, the call server 200 reads out the desired telephone number assigned to the mobile phone terminal 600 corresponding to the call from the built-in database (step S19), and receives the call request via the PSTN 500. Is called (step S20).

  On the other hand, when the outgoing call is received by the mobile phone terminal 600, the connection between the mobile phone terminal 600 and the call server 200 is made, and a call between the phone terminal 300 and the mobile phone terminal 600 becomes possible. (Step S21).

  The telephone terminal 300 can be a general telephone (fixed telephone) or a mobile phone. In such a case, the connection between the call server 200 and the telephone terminal 300 may be made via the PSTN 500.

  For example, when the user selects the radio button 30 corresponding to “callback reservation” and presses the send button area 38, the call server 200 uses the network time protocol or the like to set the reservation time. When a call arrives, a call may be made to the telephone terminal 300.
