It is a flowchart which shows the flow of the process which transmits a transmission request.

  Hereinafter, embodiments of the present invention will be described with reference to the drawings.

  FIG. 1 is an overall configuration diagram including a call support device according to the present embodiment. The calling support device 1 is disposed in a user's home, and is connected to a client terminal 2 and extension telephones 3A and 3B. The client terminal 2 communicates with the outside via the call support device 1 and can browse electronic information such as Web pages, mails, and electronic advertisements. The extension telephones 3A and 3B are connected to the call support device 1 and can use a telephone service using SIP. When using the telephone service, the call support device 1 performs call control using SIP and connects to an external telephone 4 via the network 100.

  Hereinafter, the flow of the call operation for the telephone number displayed on the client terminal 2 using the call support device 1 will be described.

  When the user clicks and selects a telephone number displayed on the client terminal 2, the client terminal 2 transmits a call request including the call destination telephone number to the call support device 1 (step S1).

  When receiving the call request, the call support device 1 calls the extension telephones 3A and 3B and confirms the call request to the user (step S2). Here, all of the extension telephones 3A and 3B may be called, or only the designated extension telephones 3A and 3B may be read out. The confirmation of the outgoing call request is performed by the user operating a push button on the extension telephones 3A and 3B. When the user presses a push button after off-hooking one of the extension telephones 3A and 3B, a push button signal corresponding to the pressed push button is transmitted from the extension telephones 3A and 3B to the calling support device 1 to make a call. The support device 1 determines whether to allow or stop calling based on the received push button signal. For example, the transmission permission is associated with the “1” button, and the transmission suspension is associated with the “9” button.

  When the confirmation of the outgoing call request is completed, the outgoing call support device 1 sends an SIP message to an SIP server (not shown) on the network 100 to make an outgoing call to the telephone 4 (step S3). A call is made (step S4).

  When the telephone 4 is off-hooked and responded, the call connected to the telephone 4 is transferred to the extension telephones 3A and 3B to which the user has responded, and a call between the two parties becomes possible (step S5). The external telephone 4 may be a mobile phone or a telephone connected to a public switched telephone network.

  Next, the call support device 1 will be described.

  The call support device 1 according to the present embodiment includes a client terminal communication unit 11, an extension control unit 12, and a SIP cooperation unit 13. Each unit included in the call support device 1 may be configured by a computer including an arithmetic processing device, a storage device, and the like, and the processing of each unit may be executed by a program. This program is stored in a storage device included in the call support device 1, and can be recorded on a recording medium such as a magnetic disk, an optical disk, or a semiconductor memory, or provided through a network. By using the OSGi framework in the call support device 1 and mounting each part as a bundle, distribution and updating of the bundle can be performed without restarting the call support device 1, and function additions and bug fixes are also available. It becomes easy. All the units may be implemented as a bundle, or some of them may be cut out natively of the call support device 1 and operated in cooperation. When each part is mounted as a bundle, a function for managing the bundle is necessary, but description thereof is omitted here. Hereinafter, each part will be described.

  The client terminal communication unit 11 communicates with the client terminal 2 and accepts a call request including a destination telephone number.

  The extension control unit 12 makes a call to the extension telephones 3A and 3B based on the call request received from the client terminal 2. In addition, authentication of the client terminal 2 and confirmation of a transmission request are also performed.

  After confirming the outgoing call request, the SIP cooperation unit 13 sends an SIP message for call connection to the destination telephone 4 to the SIP server. After the telephone 4 responds and makes the call connection, the call connected to the telephone 4 is sent. The call is transferred to the extension telephones 3A and 3B off-hooked by the user, and the telephone 4 and the extension telephones 3A and 3B are connected to enable a call.

  Next, the process flow of the call support device 1 will be described.

  FIG. 2 is a flowchart showing a process flow of the call support device 1 in the present embodiment.

  When the user clicks on the client terminal 2 an icon on the Web page or an email or a telephone call link corresponding to this function embedded in the Web page, the client terminal 2 sends a call request to the call support device 1. Is sent. And the client terminal communication part 11 receives the transmission request | requirement transmitted from the client terminal 2 (step S11). The call origination request includes the destination telephone number and is transmitted by an HTTP GET or POST request.

  If the client terminal communication unit 11 receives the first call request for the time set out from the present time by a preset timeout time, the client terminal communication unit 11 performs authentication from the viewpoint of security (step S12). Authentication is performed by general digest authentication. At this time, the authentication information necessary for authentication is embedded in the browser add-in or compatible software, or the authentication information is stored in the browser so that the user does not have to input the authentication information each time. Increase convenience.

  If the authentication passes, the extension control unit 12 calls the extension telephone 3A (step S13). Note that all the extension telephones 3A and 3B connected to the calling support device 1 may be called, or only the designated extension telephones 3A and 3B may be called. Here, it is assumed that the call is made only to the extension telephone 3A.

  When the user off-hooks the extension telephone 3A, for example, a call for permission to send to the external telephone 4 such as “please press 1 to make a call or 9 to cancel” is requested to send a call. When the user presses the push button of the extension telephone 3A, a push button signal corresponding to the push button pressed from the extension telephone 3A is transmitted to the call support apparatus 1, and the call support apparatus 1 performs a call permission operation or a stop operation. It is confirmed. Note that the speech of the talk may include reading the phone number of the destination. Further, the destination telephone number may be displayed on the client terminal 2. The operation for requesting the outgoing call is from the viewpoint of security, and is always set to the outgoing call permitted state according to the user setting. When the extension telephone 3A is off-hooked, it is assumed that the outgoing call is permitted, and the process proceeds to the next process and automatically The calling process to the telephone 4 may be started.

  When the user permits outgoing calls to the external telephone 4, the SIP cooperation unit 13 calls the telephone 4, and the extension control unit 12 transmits a ringback tone to the extension telephone 3A (step S14). A call to the telephone 4 is made by transmitting a SIP message to the telephone 4 via the SIP server. The user can recognize that a call is made to the telephone 4 with a ringback tone heard from the extension telephone 3A.

  When the telephone 4 is off-hook and responds, the call connection between the call support device 1 and the telephone 4 is completed. The SIP cooperation unit 13 transfers the call connected to the telephone 4 to the extension telephone 3A, and connects the telephone 4 and the extension telephone 3A (step S15). Call transfer is performed using SIP REFER.

  With the above processing, a call can be made between the extension telephone 3A and the telephone 4.

  Next, the client terminal 2 will be described.

  As shown in FIG. 1, the client terminal 2 in the present embodiment includes an extraction unit 21, a user interface 22, and a transmission unit 23.

  The extraction unit 21 extracts a place where a telephone number is written from the received text part such as a web page or an e-mail, and adds a telephone call link for sending a call request to the call support device 1 at that place.

  The user interface 22 presents a Web page, an e-mail, or the like to the user, and accepts a click on a telephone call link.

  The transmission unit 23 transmits a call request to the call support device 1 when the user clicks a link for calling.

  As the client terminal 2, a browser in which a browser add-in is incorporated in a browser operating on a personal computer or a dedicated application in a portable terminal can be used.

  Next, the processing flow of the client terminal will be described.

  First, a process for extracting a telephone number from electronic information such as a web page and assigning a telephone call link will be described.

  FIG. 3 is a flowchart showing a flow of processing for extracting a telephone number from a web page or the like and providing a telephone call link. The process shown in FIG. 3 is started when a Web page download start event is detected during page transition or update. In the present embodiment, only the text element of the DOM (Document Object Model) node is targeted as a phone number extraction target.

  When the download of the web page is started, it waits for the download of the web page to be completed (step S21). Specifically, when a Web page download start event is detected, a monitoring timer with a fixed period (for example, 1 second) is started, and when the monitoring timer times out, the value of the ReadyState property of the WebBrowser control is acquired, and the document reading state of the browser To get. When the document reading state is not “READYSTATE_COMPLETE”, the monitoring timer is restarted. When the document reading state is “READYSTATE_COMPLETE”, it is determined that the download of the Web page is completed, and the process proceeds to the next process.

  When the download of the web page is completed, a telephone number is extracted from the downloaded web page (step S22). Specifically, all DOM nodes in the Web page are inspected to check whether or not the DOM node is a telephone number extraction target. If it is a DOM node from which a telephone number is to be extracted, it is checked whether or not the text in the DOM node matches the telephone number pattern represented by a regular expression. If the phone number pattern matches, the location where the phone number is written and the phone number are stored in a memory or the like.

  When the telephone number is extracted, a telephone call link is added to the location where the telephone number is written (step S23). Specifically, the phone number part in the DOM node is surrounded by a span element, and a mouse over event that occurs when the mouse pointer enters the area and a mouse pointer that exits from the area. Set a listener to monitor and detect the occurrence of an event to detect a mouse-out event. In addition, as a child element of the DOM node, an a element (href attribute = “#”, title attribute = none) that is the base of a clickable icon, and an icon indicating that it is a callable telephone number as a child element of the a element Add an image in a hidden state.

  Next, display / non-display processing of the clickable icon added in the above processing will be described.

  A clickable icon is displayed when a mouse-over event is detected, and a clickable icon is hidden when a mouse-out event is detected.

  When a mouse-over event is detected, the child element (a element) of the inserted DOM node is displayed, and the destination telephone number is added to the title attribute of the child element and the memory stack used by the browser add-in. To do. As a general function, the browser has a function of displaying the text written in the title attribute at the position indicated by the mouse pointer as a tooltip, so that the destination telephone number is displayed by the function of the browser. At this time, an icon image indicating that the telephone number is callable is also displayed in a clickable form.

  On the other hand, when a mouse-out event is detected, the child element (a element) of the inserted DOM node is hidden.

  Next, processing for transmitting a call request when an icon image is clicked will be described.

  FIG. 4 is a flowchart showing a flow of processing in which the client terminal 2 transmits a call request to the call support device 1.

  When the clickable click of the clickable icon by the user is detected, a call processing thread is activated and a process of sending a call request is started with the telephone number included in the title attribute of the clickable icon as an argument. If the title attribute does not include a phone number, the phone number stored in the memory stack is used.

  First, a call start confirmation screen dialog in which the telephone number included in the title attribute is described is displayed (step S31). At this time, the telephone number in the dialog can be edited by the user in order to fulfill the desire to add a prefix of non-notification. In the dialog, a field for inputting extension numbers of the extension telephones 3A and 3B to be used is displayed. When 0 is designated as the extension number, it indicates that all the extension telephones 3A and 3B connected to the calling support device 1 are ringed. Of course, the extension telephones 3A and 3B to be used may be set in advance.

  When the OK button on the call start confirmation screen dialog is pressed, the telephone number is checked and a call request is transmitted (step S32). Since the telephone number in the dialog can be edited by the user, it is checked whether the input telephone number character includes illegal characters (characters other than numerical values, single-byte hyphens, single-byte brackets). When an illegal character is included, the user is prompted to input again. When an illegal character is not included, a call request is transmitted to the call support device 1, and the call start confirmation screen dialog is hidden, and a call status display screen dialog notifying that the call is started is displayed. When the cancel button is pressed, the dialog is hidden and the outgoing call processing thread is terminated.

  The call request includes an identifier indicating that the communication uses this function, an extension number to be called, and a telephone number of the call destination. The transmission request is transmitted by an HTTP GET or POST request. When a call request is transmitted, a response waiting timer (for example, 10 seconds) from the call support device 1 is started.

  When a response is received from the call support device 1, processing is performed according to the content of the response (step S33). Specifically, when a normal response is received, the response waiting timer is stopped, the call status display screen dialog is hidden, and the call processing thread is terminated. After the call support device 1 receives the call request, the extension telephones 3A and 3B are ringed to confirm the call request. Therefore, after the normal response is received, the call request is confirmed. The destination telephone number may be displayed on the client terminal 2.

  On the other hand, when an error response is received, the response waiting timer is stopped, the call status display screen dialog is hidden, a call result confirmation dialog including an error message corresponding to the error response parameter is displayed, and a call processing thread Exit. If the call request cannot be sent, the response waiting timer is stopped, the call status display screen dialog is hidden, and a call result confirmation dialog including a message indicating that the call request cannot be sent is displayed. Terminate the thread. Furthermore, when the response waiting timer times out, the call status display screen dialog is hidden, a call result confirmation dialog including a message indicating that the process has timed out is displayed, and the call processing thread is terminated.

  In the above example, the client terminal 2 has been described in which a browser add-in is incorporated or a telephone number is extracted from a Web page or the like by a dedicated application. However, a telephone call link should be described in advance on a Web page or an e-mail. Thus, it is not necessary to extract a telephone number, and it can also be used in a terminal such as a TV that cannot use a browser add-in or a dedicated application. When creating a telephone call link, an identifier indicating communication using this function, an extension number to be called, and information on a telephone number of a call destination are required. When the user clicks on this telephone call link, a call request containing the above information is transmitted to the call support device 1.

  As described above, according to the present embodiment, when a user clicks and selects a telephone number displayed on the client terminal 2, the client terminal 2 issues a call request including the telephone number. 1, the call support device 1 receives the call request, sends the call to the extension telephones 3A and 3B, and sends the call to the telephone number (the telephone number of the external telephone 4) included in the call request. By transferring the connected call to the extension telephones 3A and 3B, it is possible to easily make a call to the telephone 4 without manually inputting the telephone number while looking at the telephone number displayed on the client terminal 2.

  In other words, it is advantageous for the end user who is a caller to easily make a call to the outside line, greatly reducing the possibility of erroneous calls, and for a store or service center as a telephone receiver. In addition to telephone calls, it can be expected that there will be an increased number of incoming calls from fixed telephones starting from telephone numbers and links posted on Web pages, leading to increased profits.

  According to the present embodiment, since it is the call support device 1 that makes a call using SIP, it is possible to install the client terminal 2 without installing software having a SIP stack, and from a terminal that cannot be installed to the outside. The telephone 4 can be called.
