On the other hand, in the case of the so-called business phone system used in offices, etc., the call may be directly addressed to the original recipient (original recipient), but in many cases, it is the department or group to which you belong. Incoming call to common phone number. In this case, in many cases, a primary responder such as a newcomer takes over the incoming call and transfers it to the telephone terminal used by the original called party. In such a case, applying the techniques of Patent Document 1 and Patent Document 2 mentioned above solves the problem that when a person makes a call rejection registration, the call is rejected even if it is not a nuisance call for other people. occur. Therefore, the techniques disclosed in Patent Document 1 and Patent Document 2 cannot be simply applied.

Also, the original called party who received the forwarding can tell the primary responder that he does not want to forward incoming calls from XX in the future, and refuse forwarding thereafter. However, the primary responder needs to remember the caller who should not be forwarded for each called party, which poses a problem of a heavy burden on the primary responder.

In view of the above, it is an object of the present invention to transfer a call from a caller whose transfer is refused to a transferee without imposing an excessive load on the user of the transferor's telephone terminal. The purpose is to prevent

In order to solve the above problems, the telephone control device of the invention described in claim 1 comprises:
A telephone control device connected to an external telephone network and capable of accommodating two or more telephone terminals under its control,

a second reception means for receiving an extension number indicating a transfer destination of the telephone line from a transfer source telephone terminal connected to the telephone line;
When the extension number instructing the transfer destination is received through the second reception means, the transfer refusal information storage means is referred to based on the extension number, and the caller telephone number of the connected telephone line is transferred. determining means for determining whether or not the destination is the same as the telephone number of the caller whose transfer is refused;
When the determination means determines that the telephone number of the caller of the connected telephone line is the same as the telephone number of the caller whose transfer is rejected by the transfer destination, the telephone terminal of the transfer source is: and notification means for notifying that the forwarding destination has rejected the incoming call.

According to the telephone control apparatus of the first aspect of the invention, the telephone control apparatus is connected to an external telephone network and can accommodate two or more telephone terminals under its control. After the subordinate telephone terminal responds to the incoming call from the external telephone network by the first reception means and connects the telephone line (call line), the call can be made through this telephone line. You can receive a transfer rejection request. When the transfer request is accepted, the registration means registers the extension number of the transfer destination telephone terminal that transmitted the transfer refusal request and the caller's telephone number (caller's telephone number) of the connected telephone line to be transferred. It is associated and registered in the transfer refusal information storage means.

Assume that an extension number designating a transfer destination of the telephone line is accepted from the subordinate telephone terminal connected to the telephone line through the second acceptance means. In this case, the determination means refers to the transfer refusal information storage means based on the extension number, and the telephone number of the caller of the connected telephone line is the same as the telephone number of the caller whose transfer is rejected by the transfer destination. It is determined whether or not When the determination means determines that the telephone number of the caller of the connected telephone line is the same as the telephone number of the caller whose transfer is rejected by the transfer destination, the notification means notifies the transfer source telephone terminal , you will be notified that the forwarding destination has rejected the incoming call.

In this way, in response to the transfer rejection request, the extension number of the transfer destination telephone terminal that rejects the transfer and the caller's telephone number of the caller that rejects the transfer are registered in the transfer rejection information storage means. After that, the telephone control unit prevents the telephone line connected in response to the incoming call from the caller from being transferred to the transfer destination telephone terminal that has rejected the transfer.

According to the telephone control device of the present invention, when an incoming call is answered, a telephone line is connected, and the call is transferred, the caller of the incoming call is a party to which transfer is refused at the transfer destination. In some cases, the forwarding can be refused without the intervention of the forwarding user.

As shown in FIG. 7, the incoming call history DB 106 manages the history of incoming calls to the telephone control device 1, and includes the date and time of the call, the caller's telephone number, the answering terminal, the forwarding destination 1, the forwarding destination 2, Manage incoming call history data consisting of …, status, and call duration. The date and time of incoming call is the date and time (year, month, day and time) when the telephone control device 1 receives an incoming call. The caller's phone number is the phone number of the caller.

The response terminal is the extension number of the telephone terminal 3 that first responded to the incoming call, and the transfer destination 1, transfer destination 2, . In the case of the business phone system 10 of this embodiment, transfer can be repeated a plurality of times, with transfer destination 1 being the oldest, transfer destination 2, transfer destination 3, . . It is assumed that the telephone control device 1 of this embodiment can manage, for example, up to five transfer destination extension numbers. Of course, it is also possible to manage cases in which transfers are performed five times or more. For example, it is possible to configure the transfer destination management area to be variable.

The status stores information indicating the state of use of the telephone line at that time, such as "calling", "talking", "holding", and "call terminated". For example, when the transfer button of the telephone terminal 3 is operated, the status becomes "on hold", and the extension number (extension number of the transfer destination) entered from the telephone terminal 3 whose transfer button was operated is displayed in the transfer destination area. is entered (updated). As the call time, the time from when the telephone line is connected in response to the incoming call to when the telephone line is released is entered. This incoming call history data is formed by the control unit 102, recorded in the incoming call history DB 106, and updated.

The connection end 107T constitutes a connection end to the private network 2. FIG. A connection I/F (Interface) 107 enables communication between the telephone control device 1 and telephone terminals 3(1) to 3(n) accommodated in the telephone control device 1 through the private network 2. FIG. Accordingly, signals from the telephone control unit 1 to the telephone terminals 3(1) to 3(n) are converted into transmission format signals in the connection I/F 107 and sent to the telephone terminals 3(1) to 3(n). sent to. Signals from the telephone terminals 3(1) to 3(n) are converted into signals in a format that can be processed in the connection I/F 107 and captured.

Under the control of the control unit 102, the call control unit 108 uses the management information of the address management DB 104 to control the call origination, termination, response, and disconnection of the telephone terminals 3(1) to 3(n). The call control section 108 includes an outgoing call control section 1081 and an incoming call control section 1082, as shown in FIG. When the call control unit 108 receives a call (call request) from the telephone terminals 3(1) to 3(n) under its control, the call control unit 1081 functions to call the designated party, When the other party answers, the telephone line is connected to enable communication.

In addition, when the call control unit 108 receives an incoming call addressed to itself (call notification from the other party), the incoming call control unit 1082 functions to to notify you of an incoming call. As a result, in the telephone terminals 3(1) to 3(n), a ringing tone is emitted from the sound emitting unit 305 to notify the occurrence of an incoming call. When an operation to respond to an incoming call (off-hook operation) is performed on any of the telephone terminals 3(1) to 3(n), the incoming call control unit 1082 detects this, responds to the incoming call, and is off-hooked. A telephone line is connected to a subordinate telephone terminal 3 to enable communication.

After that, the process of holding, transferring, and releasing the connected telephone line is performed under the control of the control unit 102 in response to requests from the subordinate telephone terminals 3(1) to 3(n). processed to The control unit 102 also performs lighting/light-off control of LEDs (Light Emitting Diodes) included in the telephone terminals 3(1) to 3(n) under its control, display control on the display 304, and the like.

In FIG. 4, transfer refusal registration section 109, transfer refusal determination section 110, and transfer refusal notification processing section 111 are main parts for realizing the transfer refusal function in business phone system 10 of this embodiment. Transfer refusal requests (FIG. 3) from the telephone terminals 3(1) to 3(n) under the control of the telephone control device 1 are accepted through the connection terminal 107T and the connection I/F 107. FIG. In this case, under the control of the control unit 102 , the transfer refusal registration unit 109 functions to form the transfer refusal information explained using FIG. 6 and record it in the transfer refusal DB 105 .

In this case, the extension number of the requester of the transfer refusal request is used as the extension number of the transfer refusal information. In addition, the caller's phone number of the transfer refusal information is information recorded in the incoming call history DB 106, the status is "hold", and the latest transfer destination is the same extension number as the requester's extension number. The caller's telephone number of the historical information is used. In addition, the caller's phone number of the transfer refusal information is information recorded in the incoming call history DB 106, the status is "busy", and the latest transfer destination is the same extension number as the extension number of the requester. In some cases, the caller's telephone number in the call history information is used.

In this way, the transfer refusal registration unit 109 forms transfer refusal information based on the transfer refusal request from the telephone terminal 3 and the data stored in the incoming call history DB 106, and performs the process of recording this in the transfer refusal DB 105. . As the date of registration of the transfer refusal information, a system date provided by a clock circuit included in the telephone control device 1 can be used, although not shown.

When the transfer refusal determination unit 110 receives a transfer request and an extension number designating a transfer destination from the subordinate telephone terminal 3 connected to the telephone line, the caller of the currently connected telephone line is the telephone terminal 3 of the transfer destination. determines whether the transfer is rejected. Specifically, the transfer refusal determination unit 110 refers to the transfer refusal DB 105 based on the received extension number, and identifies the telephone number of the caller (caller's telephone number) for which the transfer is rejected. If the phone number of the caller who is rejecting the transfer can be identified, the incoming It is determined based on the corresponding information in the call history DB 106 . In this case, the corresponding information in the incoming call history DB 106 has the same extension number as the extension number accepted by the latest transfer destination together with the transfer request, and the status is pending.

It is assumed that the transfer refusal determination unit 110 determines that the caller of the currently connected telephone line is the caller whose transfer is rejected by the telephone terminal 3 of the transfer destination. In this case, the transfer refusal notification processing unit 111 functions under the control of the control unit 102 to transmit the transfer refusal notification to the telephone terminal 3 that has transmitted the transfer request. The forwarding refusal notice is "The forwarding destination refuses forwarding." ” and so on. As a result, the user of the telephone terminal of the transfer source notifies the caller that the call cannot be connected, performs an on-hook operation, and releases the telephone line connected to the caller. Become.

As described above, the user of the telephone terminal 3 of the business phone system 10 of this embodiment assumes that the caller of the telephone line to which the call is transferred to him is the other party whom he does not want to answer. In this case, the user of the telephone terminal 3 can form and register forwarding rejection information in the telephone control device 1 by pressing the forwarding rejection button 306A. After the transfer refusal information is registered in the telephone control unit 1, the user of the telephone terminal 3 which is the transfer destination can accept the transfer without touching the telephone terminal 3 used by himself/herself. To reliably reject transfer of a call from a rejected caller.

[Transfer refusal registration process and transfer refusal process]
Next, transfer refusal registration processing for forming and registering transfer refusal information performed by the business phone system 10 of this embodiment comprising the telephone terminal 3 and the telephone control unit 1 having the above-described configuration, and actually transferring will be described. In the following, an example will be described in which the telephone terminal (1) is used to respond to an incoming call and the call is transferred from the telephone terminal 3(1) to the telephone terminal 3(n).

The transfer refusal registration process includes a process of registering transfer refusal at the transfer destination without contacting the originator (transfer refusal registration process 1), and a process of contacting the originator at the transfer destination and then registering the transfer refusal. processing (transfer refusal registration processing 2). Further, in the transfer refusal process, the incoming call is answered and the transfer destination is instructed, but if the transfer destination rejects the incoming call, the process of notifying the transfer source of the transfer refusal (transfer refusal process 1). , and the telephone control unit 1 performs all the processing related to transfer refusal (transfer refusal processing 2). Each of these will be specifically described below.

[Transfer refusal registration process 1]
FIG. 8 is a sequence diagram for explaining transfer refusal registration processing 1 performed in the business phone system 10. As shown in FIG. First, as shown in the upper right corner of FIG. Suppose that it is hung (step S1). In the telephone control device 1 notified of the incoming call from the calling terminal 5, the incoming call control unit 1082 functions and notifies the subordinate telephone terminals 3(1) to 3(n) of the incoming call (step S2). As a result, each of the telephone terminals 3(1) to 3(n) rings an incoming call to notify the user of the incoming call.

In this case, when the telephone terminal 3(1) responds to the incoming call as the primary response terminal, this is notified to the telephone control device 1 (step S3). The telephone control device 1 notifies the calling terminal 5 of the response (step S4), connects the telephone line between the calling terminal 5 and the telephone terminal 3(1) which is the primary response terminal, and starts the call. It is made ready (step S5). As a result, the user (originator) of the originating terminal 5 and the user of the telephone terminal 3(1) make a call, so that the transfer destination intended by the originator is the user of the telephone terminal 3(n). Suppose it turns out that

The user of the telephone terminal 3(1) informs the user of the calling terminal 5 through the connected telephone line that the call will be connected to the intended transfer destination, so please wait. Press the transfer button. As a result, a transfer request is transmitted from the telephone terminal 3(1) to the telephone control device 1 (step S6). In this case, the telephone terminal 3(1) is the transfer source telephone terminal. Upon receiving the transfer request, the telephone control device 1 puts the telephone line connected to the calling terminal 5 on hold, and provides the calling terminal 5 with a holding tone (such as a melody tone indicating the holding state) through the telephone line. Then, a hold notification is issued (step S7).

The user of the transfer source telephone terminal 3(1) inputs the extension number of the telephone terminal 3(n), which is the telephone terminal of the transfer destination, through the transfer source telephone terminal 3(1). (step S8). When receiving the extension number of the telephone terminal 3(n), which is the telephone terminal of the transfer destination, the telephone control device 1 makes a call by ringing the telephone terminal 3(n) (step S9). When the user of the telephone terminal 3(n) performs a response operation (off-hook operation) in response to this call, this is notified to the telephone control device 1 (step S10). As a result, the telephone control device 1 connects the extension line between the transfer source telephone terminal 3(1) and the transfer destination telephone terminal 3(n) to enable communication (step S11). Also, in this case, the telephone terminal 3(n) becomes the transfer destination telephone terminal.

The user of the transfer source telephone terminal 3(1) makes a call to the user of the transfer destination telephone terminal 3(n), for example, "A call from Mr. XX of AAA Corporation." It will be communicated through the connected extension line that the call will be connected. In this case, it is assumed that the user of the transfer destination telephone terminal 3(n) decides that it is not necessary to answer the call from the caller, and that he/she wants to reject the subsequent transfer. In this case, the user of the transfer destination telephone terminal 3(n) presses the transfer rejection button 306A of the transfer destination telephone terminal 3(n) (step S12). As a result, a transfer refusal request is formed in the transfer destination telephone terminal 3(n), and this is transmitted to the telephone control unit 1 (step S13).

After that, the telephone control unit 1 transmits a request to disconnect the extension line to the transfer source telephone terminal 3(1), and in step S11, the extension line connected to the transfer destination telephone terminal 3(n). Release the line (step S14). Further, the telephone control device 1 provides a guidance voice such as "Transfer has been rejected" to the transfer source telephone terminal 3(1) (step S15). In the telephone control unit 1, the transfer refusal registration unit 109 functions, and the extension number of the transfer destination telephone terminal 3(n) corresponds to the telephone number of the calling terminal 5, which is the originator of the currently held telephone line. The attached transfer refusal information is formed and registered in the transfer refusal DB 105 (step S16).

The user of the transfer source telephone terminal 3(1) performs an operation to release the hold state of the telephone line connected to the calling terminal 5 put on hold in step S6, such as by pressing an answer button. (step S17). As a result, the telephone control device 1 reconnects the telephone line between the transfer source telephone terminal 3(1) and the originating terminal 5 to enable communication (step S18). As a result, the user of the transfer source telephone terminal 3(1) notifies the user of the calling terminal 5 that the call cannot be connected, performs an on-hook operation (step S19), and releases the telephone line.

In the case of this transfer refusal registration process 1, the user of the transfer destination telephone terminal 3(n) can refuse the transfer without even talking with the user of the originating terminal 5 even once. Further, in the telephone control device 1, the telephone terminal 3(n) can form transfer refusal information for refusing to transfer the incoming call from the calling terminal 5 and register it in the transfer refusal DB 105. FIG.

[Transfer refusal registration process 2]
FIG. 9 is a sequence diagram for explaining transfer refusal registration processing 2, which is another example of the processing at the time of transfer refusal registration. In the case of transfer refusal registration processing 1 in FIG. 8, it is an example of a case where the transfer refusal can be determined by knowing who the caller is. However, in fact, after trying to make a call, it may be possible to determine that the user does not want to receive the transfer of the call from this caller. This transfer refusal registration process 2 is to perform transfer refusal registration after talking with the caller.

As can be seen by comparing FIG. 9 and FIG. 8, the processing from step S1 to step S11 is performed in the same manner as the transfer refusal registration processing 1. FIG. That is, the telephone terminal 3(1) responds to a call received from the calling terminal 5 (steps S1, S2) (steps S3, S4), and the call is made between the calling terminal 5 and the telephone terminal 3(1). A line is connected (step S5). After that, the telephone terminal 3(1) performs a transfer operation to put the connected telephone line on hold (steps S6 and S7), input the extension number (step S8), and call the telephone terminal 3(n). call (step S9). When the user of telephone terminal 3(n) responds (step S10), an extension line is connected between telephone terminal 3(1) and telephone terminal 3(n) (step S11). That is, even in this transfer refusal registration process 2, the telephone terminal 3(1) is the transfer source telephone terminal, and the telephone terminal 3(n) is the transfer destination telephone terminal.

In the case of this transfer refusal registration process 2, the user of the transfer destination telephone terminal 3(n) is connected to the originating terminal 5 and requests that the transfer source telephone terminal take over the telephone line in the hold state. 3. Communicate orally through the extension line to the user in (1). In this case, the user of the transfer source telephone terminal 3(1) performs an on-hook operation on the transfer source telephone terminal 3(1) to notify this to the telephone control unit 1 and disconnect the connected extension line. (Step S21), the call handover is terminated.

On the other hand, the user of the transfer destination telephone terminal 3(n) performs a response operation such as pressing a response button (step S22), and notifies the telephone control device 1 of the response request (step S23). . As a result, the telephone line connected to the calling terminal 5 put on hold in steps S6 and S7 is taken over by the transfer destination telephone terminal 3(n), and the calling terminal 5 and the transfer destination telephone terminal 3(n) are connected. (step S24). Assume that the user of the forwarding destination telephone terminal 3(n), as a result of talking with the user of the originating terminal, determines that the call is unnecessary for him and that he does not want to answer the call again.

In this case, the user of the transfer destination telephone terminal 3(n) presses the transfer rejection button 306A of the transfer destination telephone terminal 3(n) (step S25). A transfer refusal request is formed from the transfer destination telephone terminal 3(n) and transmitted to the telephone control unit 1 (step S26). In the telephone control unit 1, when the transfer refusal request is received, the transfer refusal registration unit 109 functions to associate the extension number of the transfer destination telephone terminal 3(n) with the telephone number of the calling terminal 5 (originating telephone number). Then, transfer refusal information is formed and registered in the transfer refusal DB 105 (step S27).

Here, in the telephone control device 1, as described with reference to FIG. The telephone number of the calling terminal 5 (caller's telephone number) is known. Therefore, based on the transfer refusal request (FIG. 3) from the transfer destination telephone terminal 3(n) and the information (FIG. 7) managed by the incoming call history DB 106, the transfer refusal information explained using FIG. 6 is formed. can be registered in the transfer refusal DB 105.

After that, the user of the forwarding destination telephone terminal 3(n) informs the user of the originating terminal 5 that, for example, it is not related to the business and will refuse to make subsequent calls, and performs an on-hook operation ( Step S28), the telephone line connected to the calling terminal 5 is released. In this way, in the case of this transfer refusal registration process 2, the user of the transfer destination telephone terminal 3(n) talks with the user of the originator terminal 5, and then refuses transfer from the next time onwards. You can judge whether you are the opponent to do. In this case as well, when it is determined that the transfer of the call received from the originating terminal 5 is to be refused, a simple operation of pressing the transfer refusal button 306A causes the telephone control device 1 to Transfer refusal information can be registered.

[Transfer refusal process 1]
Next, after the transfer refusal information is registered in the transfer refusal DB 105 of the telephone control unit 1 by the transfer refusal registration process 1 (FIG. 8) or the transfer refusal registration process 2 (FIG. 9), Processing when a call is received from . FIG. 10 is a sequence diagram for explaining transfer refusal processing 1. As shown in FIG. In this case as well, a case where a call from the originating terminal 5 is first answered through the telephone terminal 3(1) and transferred to the telephone terminal 3(n) will be described as an example. Therefore, the telephone terminal 3(1) becomes the transfer source telephone terminal, and the telephone terminal 3(n) becomes the transfer destination telephone terminal.

In the processing shown in FIG. 10 as well, the processing from step S1 to step S8 is performed in the same manner as the processing shown in FIGS. That is, a call is received from the originating terminal 5 (steps S1, S2), the forwarding telephone terminal 3(1) responds (steps S3, S4), and the originating terminal 5 and the forwarding telephone terminal 3(1) A telephone line is connected between (step S5). Thereafter, the transfer source telephone terminal 3(1) performs a transfer operation (step S6), puts the connected telephone line on hold (step S7), and enters the extension number of the transfer destination telephone terminal 3(n). (step S8) to call the transfer destination telephone terminal 3(n).

In this case, the transfer refusal determination unit 110 of the telephone control device 1 performs transfer refusal determination processing (step S31). Specifically, the transfer refusal determination unit 110 refers to the transfer refusal DB 105 based on the extension number of the transfer destination from the transfer source telephone terminal 3(1) that has transmitted the transfer request, and determines the transfer destination telephone terminal 3(n). ) determines whether there are any sources that are refusing to transfer. If there is a caller who refuses to transfer, the caller's phone number is specified based on the registration information in the transfer refusal DB 105 . It is determined whether or not the transfer is to be rejected depending on whether or not the identified caller telephone number matches the caller's telephone number of the telephone line currently put on hold for transfer.

It should be noted that, in step S31, when there are a plurality of callers who refuse to transfer, the caller telephone numbers of the plurality of callers are specified. The plurality of specified caller telephone numbers and the history information of the incoming call history DB 106 in which the status is "on hold" and the transfer destination is the extension number of the telephone terminal 3(n) is entered. Compare with caller phone number. Depending on whether or not the compared telephone numbers match, it is possible to determine whether or not to reject the transfer. When it is determined that the transfer is not rejected in the determination processing of step S31, as described with reference to FIGS. 8 and 9, the transfer destination telephone terminal 3(n) is called and the transfer is performed.

When it is determined that the transfer is rejected in the determining process of step S31, the transfer rejection notification processing unit 111 functions to notify the transfer source telephone terminal 3(1) that the transfer is rejected. Provide voice guidance (step S32). The voice guidance is, for example, "The forwarding destination refuses the transfer." .” Display guidance may be provided in addition to voice guidance, or both voice guidance and display guidance may be provided. As a result, the user of the transfer source telephone terminal 3(1) performs hold release processing such as pressing the response button (step S33), and connects the telephone line with the calling terminal 5 that has been put on hold. (Step S34).

As a result, a call can be made between transfer source telephone terminal 3(1) and calling terminal 5, so the user of transfer source telephone terminal 3(1) can use calling terminal 5 to indicate that the call will not be connected. The person is notified by telephone, and an on-hook operation is performed (step S35). As a result, the telephone line connected to the calling terminal 5 is released. By registering the transfer refusal information in the transfer refusal DB 105 of the telephone control unit 1 in this way, the user of the transfer destination telephone terminal 3(n) can receive a call from the calling terminal 5 any number of times. , can reject the transfer without any response.

[Transfer refusal process 2]
In the case of the transfer refusal process 1 described with reference to FIG. 10, the transfer destination telephone terminal 3(n) has nothing to do with the transfer refusal process. However, the user of the transfer source telephone terminal 3(1) must take measures such as informing the user of the calling terminal 5 that the call cannot be connected. Therefore, it is considered to avoid bothering the user of the transfer source telephone terminal 3(1).

FIG. 11 is a sequence diagram for explaining transfer refusal processing 2. As shown in FIG. As shown in FIG. 11, it is assumed that a call is received from the calling terminal 5 (step S1). In this case, the transfer refusal determination unit 110 of the telephone control device 1 performs transfer refusal determination processing (step S41). This forwarding determination process is a process of determining whether or not the telephone number (caller's telephone number) notified from the caller of the incoming call (incoming call) is registered in the forwarding refusal DB 105 .

Suppose that it is confirmed that the caller's telephone number is not registered in the transfer refusal DB 105 in the determination processing of step S41. In this case, as shown in steps S1 to S8 in FIG. 10, the telephone terminals 3(1) to 3(n) are notified of the incoming call, and the response process is performed.

When it is confirmed in the discrimination process of step S41 that the caller's telephone number is registered in the transfer refusal DB 105, the telephone control device 1 automatically responds to the incoming call (step S42). Next, the transfer refusal notification processing unit 111 functions to provide voice guidance such as "We are unable to connect your call. We are sorry." to the calling terminal 5 (step S43). be released.

In addition, in the process of step S41, in order to maintain accuracy, a process of comparing the history information of incoming call history DB 106 and the registered information of transfer refusal DB 105 may be performed. This matching process is a process of confirming the presence of a telephone terminal 3 that has not been registered as forwarding refusal even if the call is from the same caller telephone number.
Assume that there is no telephone terminal 3 that is not registered for forwarding refusal even if the call is from the same caller telephone number. In this case, by the processing of steps S42 and S43 described above, the telephone terminals 3(1) to 3(n) will not be notified of the incoming call, but will automatically respond and provide guidance to the effect that the call will not be connected. After providing it, the process of releasing the telephone line is performed.

On the other hand, even if the incoming call is from the same caller telephone number, if it is possible to confirm the existence of the telephone terminal 3 that is not registered for forwarding rejection, the telephone terminal 3 that is registered for forwarding rejection does not exist. Even if the caller is forwarded, it is not determined that the caller is the other party whose transfer was refused. In this case, as described with reference to FIG. 10, the subordinate telephone terminals (1) to 3(n) are notified of the incoming call and urged to respond. As a result, even if the caller is rejected by some users, if the transfer is not rejected by other users, the call will be forwarded and the subsequent processing will be as follows. A process conforming to the transfer refusal process 1 described with reference to FIG. 10 may be performed.

In this way, in the case of the transfer refusal process 2, the user of the transfer source telephone terminal 3 can be saved as little as possible. In addition, by adopting the process of comparing the history information of the incoming call history DB 106 and the registered information of the transfer refusal DB 105, the accuracy of the transfer refusal can be maintained, and the call from the caller whose transfer is truly refused can be handled. , can refuse to transfer.

[Effects of Embodiment]
In the case of the embodiment described above, the user of the telephone terminal 3 can register the transfer refusal information in the telephone control device 1 simply by pressing the transfer refusal button 306A of the telephone terminal 3 . As a result, by using the transmission refusal information, it is possible to reliably avoid forwarding the call from the other party whose forwarding is to be rejected. Moreover, in this case, there is no need for the user of the forwarding telephone terminal 3 to keep track of information such as which telephone terminal 3 user refuses forwarding from which caller. The load on the user of the terminal 3 does not increase.

Further, when the transfer refusal information is registered, the decision as to whether or not to reject the transfer can be made without actually speaking with the user of the telephone terminal of the caller, and the transfer refusal registration can be performed. It is also possible to make a decision by actually talking with the user of the telephone terminal of the originator, and to register the forwarding refusal. Therefore, it is possible to appropriately determine transfer refusal. Through these things, it is possible to refuse the transfer of a call from the other party that is not necessary for oneself, without bothering other people as much as possible.
