Description

  The present invention relates to a telephone system used for an extension telephone system in an office.

A basic function of the telephone system is an incoming call transfer function (see, for example, Patent Documents 1 to 4). In a general telephone system, when group absence transfer / extension absence transfer is set, all incoming calls are transferred regardless of the type of incoming call from an outside line (especially an important customer) or an extension. In such an operation, for example, when an absent forwarding destination is set in a conference room in an intra-office conference or the like, absent forwarding is performed even for an incoming call from an extension (in-house). For this reason, the meeting was interrupted unnecessarily, and there were aspects that could not be said to be a detailed service.

As described above, the existing incoming call transfer function transfers all incoming calls blindly, which is inconvenient in some cases.
The present invention has been made in view of the above circumstances, and an object of the present invention is to provide a telephone system capable of performing call forwarding only for a necessary incoming call and thereby providing a detailed service. is there.

  In order to achieve the above object, according to one aspect of the present invention, in a telephone system including a plurality of telephone devices, a calling number registration table in which a caller number and a transfer destination thereof are associated with each other for the plurality of telephone devices. And a specifying means for searching the calling number registration table based on the caller number of the caller included in the incoming call and specifying a transfer destination corresponding to the incoming call number of the incoming call, and specified by the specifying means There is provided a telephone system comprising transfer control means for transferring the incoming call to a transfer destination.

  By taking such means, the calling number registration table is searched when an incoming call occurs, and the calling number registration table is searched based on the caller number of the caller included in the incoming call. The forwarding destination corresponding to the incoming call number is specified. Then, the incoming call is transferred to the specified transfer destination. That is, since the transfer destination is specified for each caller number, it is possible to perform detailed transfer processing.

  According to the present invention, missed transfer can be performed only for a necessary incoming call, and a telephone system capable of providing a detailed service can be provided.

  FIG. 1 is a system diagram showing an embodiment of a telephone system according to the present invention. This system has an IP (Internet Protocol) network as a core, and implements telephone communication via this IP network, and forms a so-called VoIP (Voice over IP) system. The IP network is realized as an intranet formed in an office, for example. A group A composed of a plurality of IP telephones A1 to Am and a conference room terminal B are connected to the IP network.

  The IP network is connected to a PBX (Private Branch eXchange) device 20 via a router 30. The PBX device 20 controls the mutual call connection of the IP telephones A1 to Am or the conference terminal B, thereby realizing an extension call within the IP network. The PBX device 20 connects the IP network and an external public network, and communicates with the IP telephones of the groups A and B and the facsimile apparatus 11, telephone set 12, softphone apparatus 13, and mobile terminal 14 belonging to the public network. Also possible. Further, the PBX device 20 includes a database 40, and a calling number registration table to be described later is stored in the database 40.

  FIG. 2 is a functional block diagram showing the PBX device 20 of FIG. The PBX device 20 includes a central processing unit 31, a memory 32 that stores programs and data used for various controls by the central processing unit 31, and an exchange processing unit 33. The exchange processing unit 33 is connected to the public network and the router 30, and performs various incoming processing (group incoming etc.) under the control of the central processing unit 31.

  The central processing unit 31 includes a specific processing unit 31a and a transfer control unit 31b as processing functions according to this embodiment. The identification processing unit 31a accesses the database 40 when an incoming call arrives, searches the calling number registration table based on the calling party's calling number included in the incoming call, and specifies the transfer destination corresponding to the called number. To do. The transfer control unit 31b transfers the incoming call to the transfer destination specified by the specification processing unit 31a.

  FIG. 3 is a diagram showing an example of the calling number registration table stored in the database 40 of FIG. The calling number registration table is a table in which a caller number and a transfer destination thereof are associated with each incoming number of the IP telephones A1 to Am. The incoming numbers of the IP telephones A1 to Am may be extension numbers or group incoming numbers. In the above configuration, each operation during group absent transfer and extension absent transfer will be described.

(Operation during group absence transfer)
This operation is a function for automatically transferring an incoming call to a conference room or group phone when the user (extension group) leaves the seat at a conference or the like. First, in the calling number registration table of the database 40, a calling number for performing group absent transfer is registered in advance. Next, the “group absence transfer destination” of the extension group A is set in the conference room terminal B.

  In this state, when there is an incoming call to the extension group A, the PBX device 20 acquires the calling party's calling number (for example, 03-XXXX-YYYY), and compares this calling number with the calling number registration table. If this calling number is registered in the calling number registration table, the group absence transfer is performed and the incoming call is received at the conference room terminal B (extension bbb). On the other hand, if it is an incoming call from a caller not registered in the calling number registration table, the PBX device 20 does not carry out the group absence transfer and makes the incoming call to the extension group A as it is.

(Operation during extension absence transfer)
This operation is a function for automatically transferring an incoming call to a conference room or group phone when the user (extension) leaves the seat at a conference or the like. First, in the calling number registration table of the database 40, the calling number for executing the extension absence transfer is registered in advance. Next, for example, “extension absent transfer destination” of the IP telephone set A1 is set in the conference room terminal B.

  In this state, when there is an incoming call to the IP telephone A1, the PBX device 20 obtains the calling party's calling number, compares it with the calling number registration table, and forwards the group only to the incoming call from the registered calling party. To the conference room terminal B. If it is an incoming call from a caller that is not registered in the calling number registration table, the group absence transfer is not performed and the extension group A is made to receive the incoming call.

  As described above, in this embodiment, a calling number registration table in which a caller number and a transfer destination thereof are associated with each incoming number of the IP telephones A1 to Am is stored in the database 40 of the PBX device 20 in advance. When an incoming call occurs, the calling number registration table is searched based on the caller number of the caller included in the incoming call, and the transfer destination corresponding to the incoming call number of the incoming call is specified. Then, the incoming call is transferred to the transfer destination only when the transfer destination is specified, and when the transfer destination is not specified, that is, when it is not registered in the calling number registration table, normal incoming call processing is performed. Yes.

  Since it did in this way, it can prevent that an incoming call is transferred blindly, and the transfer to the transfer destination according to a user's setting is realized. Therefore, the missed transfer can be performed only for a necessary incoming call, and this makes it possible to provide a telephone system that can provide a fine service.

[Second Embodiment]
In the first embodiment, when the group absence transfer / extension transfer function is implemented, the calling number registration table is collated based on the caller ID (external line) of the caller, and the missed transfer is performed only for necessary incoming calls. I was trying to do it. In this embodiment, a technique for realizing the following functions in addition to this function is disclosed. In other words, even for telephone numbers registered in the calling number registration table, it may not be necessary to transfer an incoming call from a partner company, for example. In the present embodiment, a description will be given of a telephone system that can cope with a user's request more finely by preventing transfer in such a case.

  FIG. 4 is a diagram showing another example of the calling number registration table stored in the database 40 of FIG. The calling number registration table of this embodiment is obtained by grouping the calling number registration table of FIG. 3 in advance for each caller number, and associating the on / off attribute of incoming call forwarding with each group. The operation using this table will be described below.

(Operation during group absence transfer)
This function is a function for automatically transferring an incoming call to a conference room or a group phone when the user (extension group) leaves the seat at a conference or the like. First, in the table of FIG. 4, a calling number that may carry out group absence transfer is registered in advance for each group such as “customer”, “cooperating company”, and “business partner”. Next, for the extension group A, the group absence transfer whose calling number registration group is “customer” is enabled (On), and the transfer destination is set to the conference room terminal B.

  If there is an incoming call to the extension group A from this state, the PBX device 20 obtains the calling party's calling number, collates the telephone number in the calling number registration group “customer” for which the group absent forwarding is valid, The group absence transfer is performed only for incoming calls from registered senders, and the conference room terminal B receives the incoming calls.

  On the other hand, if a call is received from a telephone number registered in the calling party registration group “cooperating company” for which the group absence forwarding is disabled (Off), or a telephone number not registered in any calling party registration group For example, the PBX device 20 does not carry out the group absence transfer but makes the incoming call to the extension group A as it is.

(Operation during extension absence transfer)
This function is a function for automatically transferring an incoming call to a conference room or a group phone when the user (extension) leaves the seat at a conference or the like. In the above setting, when there is an incoming call to the IP phone A1, the PBX device 20 acquires the caller's calling party number, and collates the telephone number in the calling party registration group “customer” for which the extension extension forwarding is valid. The extension absence transfer is executed only for the incoming call from the registered transmission source, and the conference room terminal B is made to receive the incoming call.

  If the incoming call is from a telephone number registered in the calling number registration group “Cooperating company” for which the extension extension forwarding is disabled (Off), and a telephone number not registered in any calling number registration group, PBX The device 20 does not carry out the extension absence transfer and causes the IP telephone A1 to receive the call as it is.

  As described above, in the present embodiment, when the group absent transfer / extension transfer function is performed, the calling number registration table for determining whether or not to perform the group absent transfer / extension transfer function is divided into groups, and for each group. Unattended transfer is implemented. Since it did in this way, the service with respect to a user can be made still finer.

  Note that the present invention is not limited to the above-described embodiment as it is, and can be embodied by modifying the constituent elements without departing from the scope of the invention in the implementation stage. In addition, various inventions can be formed by appropriately combining a plurality of components disclosed in the embodiment. For example, some components may be deleted from all the components shown in the embodiment. Furthermore, constituent elements over different embodiments may be appropriately combined.
