Description

The present invention relates to, for example, a telephone device that provides convenient functions for both a source and a destination in the event of making an erroneous call.

Sometimes I make a mistake when I make a call. Incorrect calls may be noticed by the other party in response, but often noticed before the other party answers. At this time, if the ringback tone (ringing tone) is not heard from the handset, it is before the ringing tone is emitted at the other party, so there is no problem even if the call is disconnected by on-hooking. However, even if you realize that you made a mistake, if you hear the ringback tone and then on-hook and disconnect, the ringing tone will be emitted even at the other party, so I feel uncomfortable. I can close. Moreover, nowadays, if you do not make a call without notification, the caller's phone number may remain at the other party.

On the other hand, even if you are aware that you have made a wrong call and know that you need to apologize to the other party, it is not good mentally to keep waiting until the other party responds. Therefore, as disclosed in Patent Document 1 described later, it is conceivable to leave a message to the effect that the call is incorrect when the other party does not answer. The invention disclosed in Patent Document 1 is an invention relating to an IP telephone terminal capable of transmitting a message even when the destination telephone terminal or telephone system does not support the answering function.

Patent No. 5110307

The invention disclosed in Patent Document 1 is intended to leave a message when the other party does not support the answering machine function and does not answer, and the other party may answer immediately and make a wrong call. It is not applicable when That is, even if you make a call, notice that you made a wrong call, already hear the ringback tone, and the other party is not answering, the caller disconnects by on-hooking. , It is desirable not to be rude to the other party.

In view of the above, according to the present invention, if the other party notices that he / she has made an erroneous call before answering, he / she will not be rude to the other party even if he / she disconnects the call, and a call charge will be incurred. The purpose is to prevent you from doing anything.

In order to solve the above problems, the telephone device of the invention according to claim 1 is
A call processing means that sends outgoing information to the telephone network to call the other party in response to an instruction from the user and makes a call to the other party.
A timekeeping means for measuring the time from sending the transmission information through the transmission processing means to accepting the on-hook operation, and
A discriminating means for determining whether or not the time measured by the timekeeping means is within a predetermined time, and
The determination means determines that the time measured by the timing means is within the predetermined time, and if the other party does not answer, a message indicating that the call is incorrect is sent to the telephone network. , The message providing means provided to the telephone terminal of the other party, and
After sending the message through the message providing means, it is characterized by including a canceling means for canceling a series of connection processes for connecting a telephone line triggered by sending the transmitted information.

According to the telephone device of the invention according to claim 1, the outgoing call processing means sends out the outgoing call information to the telephone network to make a call, but after the outgoing call information is sent to the telephone network by the timekeeping means. , The time is measured before the on-hook operation is performed. The determination means determines that the time measured by the timekeeping means is within a predetermined time, and if the other party does not answer, the message providing means sends a message to the telephone network to the effect that the call is incorrect. It is provided to the other party's telephone terminal. After that, the canceling means cancels a series of connection processes for connecting the call line triggered by the transmission of the outgoing information, and the call is disconnected.

According to the present invention, when the time from the transmission of the outgoing information to the on-hook is within a predetermined time, a message indicating that the call is incorrect is transmitted to the other party and the call is disconnected. As a result, even if the other party disconnects before answering, a message indicating that the call is incorrect can be provided to the other party, so that it will not be rude. Moreover, since the call can be released without securing a call line, it is possible to prevent a call charge from being incurred.

Hereinafter, an embodiment of the apparatus of the present invention will be described with reference to the drawings. In the embodiment described below, an example is taken when the telephone device according to the present invention is applied to a SIP server as a telephone control device used in a business phone system (button telephone system) constructed in a company office or the like. I will explain.

[Business phone system configuration example]
FIG. 1 is a diagram for explaining a configuration example of the business phone system of this embodiment. As shown in FIG. 1, a plurality of IP telephone terminals 3 (1), 3 (2), 3 (3), ... Are connected to the SIP server 1 through a LAN (Local Area Network) 2. , Business phone system is configured. The SIP server 1 is also connected to the wide area network 4. In this embodiment, the wide area network 4 is mainly an IP telephone network, but also includes a public switched telephone network and a mobile telephone network.

The SIP server 1 is to which the telephone device according to the present invention is applied, and controls the call of the (subordinate) IP telephone terminal connected to the own device. In addition, call control allows you to make a call, receive a call, connect a call line (telephone line) to enable a call, disconnect the connected call line, etc. It means a series of controls for turning off. Each of the IP telephone terminals 3 (1), 3 (2), 3 (3), ... Realizes a function of making a call through a telephone line connected to the telephone terminal of the other party.

That is, each of the IP telephone terminals 3 (1), 3 (2), 3 (3), ... Is an IP telephone terminal 5 or a mobile phone terminal 5 connected to the wide area network 4 via the SIP server 1 (FIG. You can make an outside line call with (not shown). In addition, each of the IP telephone terminals 3 (1), 3 (2), 3 (3), ... Can make an extension call with another IP telephone terminal connected to the LAN 2 via the SIP server 1. can. The IP telephone terminal 5 as an outside line telephone may be independently connected to the wide area network 4, or may be connected to the wide area network 4 as a telephone terminal of another business phone system.

In the business phone system of this embodiment, a new function related to an unprecedented wrong call is made available. False calls can be divided into two cases. One is a case where when a call is made, the other party answers without noticing that the wrong call has been made, and the other party's response makes the first notice that the wrong call has been made. In this case, you can directly apologize for making a wrong call to the other party.

The other is when you make a call and immediately notice that you made a mistake and immediately go on-hook before the other party answers. In this case, since the telephone line is not connected, it is not possible to apologize directly to the other party, so it is rude to the other party. Even in the latter case, the business phone system of this embodiment makes it possible to deal with the other party as little as possible.

Specifically, the SIP server 1 spreads outgoing information including the telephone number of the other party in a wide area in response to a request from the IP telephone terminals 3 (1), 3 (2), 3 (3), ... The time from when the other party is called to the network 4 to when it is on-hooked is measured. The measurement of this time is stopped when the other party responds. This is because you can apologize directly through the connected telephone line. However, if the other party does not respond and the measured time is within a predetermined time (within a predetermined fixed time), for example, within 3 seconds, it is highly probable that an erroneous call has been made. Therefore, the SIP server 1 automatically sends a message indicating that the call is an incorrect call to the other party, then cancels a series of connection processes and releases the call from the caller (connection with the caller). release).

As a result, even if you notice a wrong call immediately after making a call and immediately perform an on-hook operation, a message is provided to the other party to inform you that it is a wrong call, so you can avoid being rude to the other party. .. Moreover, since no call line is secured (connected), no call charges are incurred. Thus, in this embodiment, the wrong call notices the wrong call by itself before the other party answers, and on-hooks within a predetermined time from the transmission of the outgoing information, so that the call line is not connected and the call line is directly apologized. Means when it cannot be done.

Hereinafter, configuration examples of the SIP server 1 and the IP telephone terminals 3 (1), 3 (2), 3 (3), ... Of the business phone system of this embodiment will be described. Since each of the IP telephone terminals 3 (1), 3 (2), 3 (3), ... Is configured in the same manner, the IP telephone terminal 3 is not specified unless it is necessary to distinguish them from each other. Collectively referred to as.

[Configuration example of SIP server 1]
FIG. 2 is a block diagram for explaining a configuration example of the SIP server 1 that functions as a telephone control device in the business phone system of the embodiment. The connection end 101T constitutes a connection end to the wide area network 4. The communication I / F (Interface) 101 is a part that performs communication processing through the wide area network 4. That is, the communication I / F 101 converts the signal addressed to the own machine transmitted via the wide area network 4 into a signal in a format that can be processed by the own machine, and captures the signal. Further, the communication I / F 101 converts a signal transmitted from its own device to a target destination, converts it into a signal in a transmission format, sends it to the wide area network 4, and transmits it to the destination.

Although not shown, the control unit 102 is a microprocessor including a CPU (Central Processing Unit), a ROM (Read Only Memory), a RAM (Random Access Memory), a non-volatile memory, and the like, and controls each unit of the SIP server 1. In addition, the control unit 102 can also perform decomposition processing and generation processing of various data such as control data and voice data that are transmitted and received in packets.

The storage device 103 is a device unit including a recording medium and its driver, such as an HDD (Hard Disk Drive) and an SSD (Solid State Drive), and records, changes, deletes, reads, and the like of various data. .. The storage device 103 is used as a work area for temporarily storing intermediate data generated in various processes, in addition to storing and holding necessary data and programs.

The address management DB 104 is created in a recording device unit such as an HDD or SSD, and stores and holds address information and other management information about the IP telephone terminal 3 housed in the own machine. FIG. 3 is a diagram for explaining an example of stored data of the address management DB 104 of the SIP server 1. As shown in FIG. 3, the address management DB 104 includes an "extension number", an "IP (Internet Protocol) address", a "port number", and a "number of mistakes" for each IP telephone terminal 3 accommodated in the SIP server 1. , "Other" information is stored and retained.

The "extension number" is a number for an extension telephone assigned to all the IP telephone terminals 3 accommodated in the SIP server 1. The IP address is information that is assigned to a device that can connect to the Internet by, for example, a DHCP (Dynamic Host Configuration Protocol) server, and can uniquely identify each device that can connect to the Internet. In this embodiment, an IP address is assigned to each of the IP telephone terminals 3 housed in the SIP server 1.

The "port number" is a port number used by each of the IP telephone terminals 3. The "number of mistakes" means that when a call is made, the time from when the outgoing information is sent to call the other party to when the on-hook operation is performed is within a predetermined time, for example, within 3 seconds, and the other party makes a call. This is the number of times when no response is made. That is, the "number of mistakes" is a case where a call is made through the IP telephone terminal 3, and the time from when the other party sends out outgoing information and calls the other party to the on-hook operation without answering is predetermined. This is the number of times when there is a high probability that the call is a mistaken call within an hour. Here, "when the probability is high" means that even if the other party is not wrong, if for some reason the other party goes on-hook before responding, the other party will be treated. Since it will be rude, this case is also included in the wrong call.

As shown in FIG. 3, the column of "number of mistakes" is, for example, a storage area for the number of times for each day for 31 days (1 month) (31 storage areas from 1st to 31st). ) Is provided. The number of incorrect calls for each day for the last 31 days including the current day is stored in this. As a result, for example, the number of wrong calls yesterday, the number of wrong calls yesterday and today, the number of wrong calls for the last 7 days, etc. It becomes possible to grasp.

As "others", for example, it is possible to add various necessary information such as a MAC address (Media Access Control address) and a URL (Uniform Resource Locator) of the IP telephone terminal 3. From the stored data of the address management DB 104, the SIP server 1 can grasp each of the IP telephone terminals 3 accommodated in the own machine.

The connection end 105T constitutes a connection end to LAN2. The LANI / F (Interface) 105 enables communication between the SIP server 1 and the IP telephone terminal 3 accommodated in the SIP server 1 through the LAN 2. Therefore, the signal from the SIP server 1 to the IP telephone terminal 3 is converted into a signal in a transmission format by the LANI / F 105 and transmitted to the IP telephone terminal 3. Further, the signal from the IP telephone terminal 3 is converted into a signal in a format that can be processed by the own machine in the LANI / F105 and taken in.

Under the control of the control unit 102, the call control unit 106 uses the management information of the address management DB 104 to perform call control such as outgoing call, incoming call, answering, and disconnection of the IP telephone terminal 3 under its control. As shown in FIG. 2, the call control unit 106 includes a transmission control unit 1061 and an incoming call control unit 1062. When an outgoing call (outgoing call request) is received from the subordinate IP telephone terminal 3, the outgoing call control unit 1061 functions to send out outgoing information to the instructed other party to call the other party, and the other party is called. When responds, connect the call line and enable the call. In addition, the outgoing call control unit 1061 also performs a process of canceling (cancelling) the connection process when it is on-hooked when the call line connection process is performed in response to the outgoing call request.

When an incoming call addressed to the own device (outgoing notification from the other party) is received, the incoming call control unit 1062 functions to notify the subordinate IP telephone terminal 3 of the incoming call. As a result, the IP telephone terminal 3 emits a ringing tone and notifies the occurrence of an incoming call. When an operation for answering an incoming call (off-hook operation) is performed on the IP telephone terminal 3, the incoming call control unit 1062 detects this, answers the incoming call, and communicates with the subordinate IP telephone terminal 3 that has been off-hooked. Connect a telephone line to the phone to enable calls.

In the SIP server 1 of this embodiment, the process of suspending, transferring, or releasing the connected telephone line is controlled by the control unit 102 in response to a request from the subordinate IP telephone terminal 3. Processed under. Further, even when the proxy response function is used after the incoming call notification, the processing is performed under the control of the control unit 102 in response to the request from the subordinate IP telephone terminal 3. In addition, the control unit 102 also performs lighting / extinguishing control of the LED (Light Emitting Diode) included in the subordinate IP telephone terminal 3 and display control on the display.

The timer circuit 107 receives an outgoing call request from the subordinate IP telephone terminal 3, sends out outgoing information to the wide area network 4, and calls the other party. From the time when the outgoing call request source IP telephone terminal 3 sends an on-hook signal. Measure the time until the time when is sent. That is, the starting point is the time when the outgoing call request is received from the subordinate IP telephone terminal 3 and the outgoing call information formed by the function of the outgoing call control unit 1061 is sent to the wide area network 4 to call the other party. After that, the end point is the time when the on-hook operation is performed on the source IP telephone terminal 3 and the on-hook signal is transmitted to the SIP server 1. The timer circuit 107 measures the time from the start point to the end point, and notifies the error telephone determination unit 108 of the measurement result.

The timer circuit 107 measures the time when the other party who made the call performs a response operation to transmit a response message from the other party and receives the response message through the connection end 101T and the communication I / F 101. Timekeeping) is finished. The timer circuit 107 measures the time from when the other party is called by sending out the outgoing information until the on-hook operation is performed on the subordinate IP telephone terminal 3 without the other party responding, thereby making a wrong call. This is to detect the case where there is a high probability that the phone has been used. Therefore, when the called party answers, the measured time is meaningless and the wrong call determination unit 108 is not notified.

The erroneous telephone discrimination unit 108 determines whether or not the time measured by the timer circuit 107 is within a predetermined time, for example, 3 seconds, and if it is determined that the time is within the predetermined time, the determination result is determined. It is provided to the apology message providing unit 109. The apology message providing unit 109 functions when the error telephone determination unit 108 provides a determination result indicating that the measurement time of the timer circuit 107 is within a predetermined time. In this case, the apology message providing unit 109 forms a message (apology message to apologize for the wrong call) such as "I made a mistake. I'm sorry." And it is transmitted to the other party through the connection end 101T. The apology message is displayed on the display unit of the other party's telephone terminal and is provided to the other party's user.

In this way, when a call is made by the functions of the timer circuit 107, the wrong call determination unit 108, and the apology message providing unit 109, and the other party is on-hook within a predetermined time from the transmission of the outgoing information before the other party answers. Is likely to be a false call. In this case, an apology message can be sent to the other party as described above. After the transmission of this apology message, the transmission control unit 1061 controls to cancel (cancel) the connection process of the call line so that the call line is not connected. As a result, no call charges are incurred.

When the apology message providing unit 109 provides the apology message, the erroneous telephone counting unit 110 counts up the "number of mistakes" of the IP telephone terminal 3 that is the source of the address management DB 104. As described above, the "mistake count" column of the address management DB 104 includes 31 storage areas, and the error call counting unit 110 counts the storage area of the corresponding day in the "mistake count" column. Count up.

Of course, the false call counting unit 110 can be configured to function in the same manner as the apology message providing unit 109. That is, when the determination result of the error call determination unit 108 indicates that the determination result is within a predetermined time, the error call counting unit 110 may be configured so as to count up the "number of errors" of the address management DB 104. ..

When the erroneous call frequency determination unit 111 receives the outgoing call request from the subordinate IP phone terminal 3, the erroneous call frequency determination unit 111 refers to the "wrong number of times" of the IP phone terminal 3 in the address management DB 104, and refers to the number of erroneous calls in a predetermined period. Determines whether or not is greater than or equal to a predetermined number of times. In this embodiment, the erroneous call frequency determination unit 111 determines, for example, whether or not the number of erroneous calls in the last 7 days is 5 times or more with respect to the source IP telephone terminal 3, and when it is 5 times or more. , Notify this to the alert providing unit 112.

The alert providing unit 112 functions when the error call frequency determination unit 111 notifies the IP telephone terminal 3 of the calling source of the determination result that the number of errors in the predetermined period is equal to or greater than the predetermined number of times. Specifically, as described above, when the IP telephone terminal 3 of the sender is notified of the determination result that the number of mistakes in the last 7 days is 5 or more, the alert providing unit 112 receives a notification. Function.

The alert providing unit 112 temporarily stops the transmission processing of the transmission control unit 1061 through the control unit 102. After that, the alert providing unit 112 provides the calling source IP telephone terminal 3 with an alert message through the LANI / F 105 and the connection end 105T, and requests confirmation input as to whether or not to continue the outgoing call processing. To. The warning message is, for example, "There are many wrong calls. Is the other party's phone number correct? If you like, please press" * ". ".

In addition, the alert providing unit 112 can provide the IP telephone terminal 3 of the sender including the telephone number of the other party so that the telephone number can be confirmed. Further, when the call source IP telephone terminal 3 makes a call using the accumulated data of the telephone directory memory provided in the SIP server 1, the alert providing unit 112 makes a call using the name (name) of the other party. It is also possible to provide the name of the other party so that the name of the other party can be confirmed. Of course, it is also possible to notify by including both the telephone number and name of the other party and output this.

After sending the alert message, in this embodiment, it is assumed that an operation signal indicating that "*" has been operated is transmitted from the IP telephone terminal 3 of the caller. In this case, the alert providing unit 112 controls the transmission control unit 1061 through the control unit 102 to continue the transmission processing that is temporarily stopped, and transmits the transmission information to call the other party. On the other hand, it is assumed that the on-hook signal is transmitted from the IP telephone terminal 3 of the sender after the alert message is sent. In this case, the alert providing unit 112 controls the outgoing call control unit 1061 through the control unit 102, terminates the outgoing call processing that is temporarily stopped, and receives the arrival of the next outgoing call request from the subordinate IP telephone terminal 3. I will wait.

In this way, if the functions of the wrong call counting unit 110, the wrong call frequency determination unit 111, and the alert providing unit 112 are used to make a call using the IP telephone terminal 3 having a high frequency of wrong calls, an error is made. You can call attention not to call. In the case of a business phone system formed in a company office, the IP phone terminal 3 is often placed at a fixed position, and the user is fixed to some extent. Can be urged to deter false calls.

[Configuration example of IP telephone terminal 3]
FIG. 4 is a block diagram for explaining a configuration example of the IP telephone terminal 3 housed in the SIP server 1 of the embodiment. Although not shown, the control unit 310 is a microprocessor provided with a CPU, ROM, RAM, non-volatile memory, etc., and controls each unit of the IP telephone terminal 3. The control unit 310 also performs decomposition processing and generation processing of various data such as control data and voice data that are transmitted and received in packets.

The connection end 301T constitutes a connection end to LAN2. The LANI / F301 realizes the connection with the SIP server 1 through the LAN 2. That is, the LANI / F301 performs a process of converting a signal transmitted to the own machine into a signal in a format that can be processed by the own machine and taking the signal into the own machine. Further, the LANI / F301 performs a process of converting a signal transmitted from its own unit into a signal for transmission and transmitting the signal. The IP telephone terminal 3 of this embodiment is wiredly connected to the SIP server 1 through the connection end 301T and the LANI / F301.

The handset 302 is provided with a speaker (handset) and a microphone (transmitter). Further, the IP telephone terminal 3 is in the on-hook state when the handset 302 is placed in the fixed position of the housing of the IP telephone terminal 3, and is in the off-hook state when picked up from the fixed position of the housing of the IP telephone terminal 3. I'm talking. Therefore, the IP telephone terminal 3 is provided with a configuration in which the control unit 310 can grasp these hook states.

The codec 303 receives the supply of packet-decomposed voice data in the control unit 310, compresses and decompresses it, converts it into an analog voice signal, and supplies it to the speaker of the handset 302 in the off-hook state. As a result, the sound from the other party is emitted from the speaker of the handset 302. Further, the codec 303 converts the analog audio signal picked up by the microphone of the handset 302 in the off-hook state into a digital signal, compresses the data, and supplies the analog audio signal to the control unit 310. The control unit 310 packetizes the voice data from the codec 303 and transmits this to the other party through the LANI / F301 and the connection end 301T.

The operation input unit 304 receives the operation input from the user and provides the received information to the control unit 310. The operation input unit 304 is provided with a numeric keypad and a plurality of function keys. In addition to this, a so-called line key or the like that can set an outside line key, an extension key, a park hold key, or the like may be provided.

The LED (Light Emitting Diode) unit 305 is composed of, for example, a plurality of LEDs provided corresponding to function keys and numeric keys, and is controlled to be turned on, blinked, and turned off by the control of the control unit 310. For example, the LED corresponding to the line key on which the outside line key or the extension key is set is controlled to blink when the telephone line is put on hold in association with the line key. Further, the LED corresponding to the line key in which the park hold key is set is controlled so as to be lit in association with the line key when the call line is put on hold. The content of the control described here is an example, and the control of lighting, blinking, and extinguishing can be performed in various modes.

The ringer 306 emits a ringtone when receiving an incoming call under the control of the control unit 310. In addition, the ringer 306 can also emit a warning sound in the case of an erroneous operation, a voice message, or the like under the control of the control unit 310. The display 307 includes a display controller, and under the control of the control unit 310, for example, as shown in FIG. 1, various displays 307 are displayed on the display screen of the display 307 provided on the front surface of the IP telephone terminal 3, for example, on the upper right end side. Performs the process of displaying information. The displayed information includes various information such as the telephone number of the other party entered, the telephone number of the caller, the guidance message, the warning message, and the above-mentioned warning message.

As shown in FIG. 1, the IP telephone terminal 3 having such a configuration is housed in the SIP server 1, and can make an outside line call, receive an outside line call, or make an extension call via the SIP server 1. , You can receive extension calls.

[Operation of business phone system]
The processing performed in the business phone system of this embodiment when an erroneous call is made from the IP telephone terminal 3 will be described. As described above, in this embodiment, the wrong call means a case where the wrong call is noticed by the other party before the other party answers and the wrong call is on-hooked within a predetermined time from the transmission of the outgoing information.

<Basic processing>
FIG. 5 is a timing chart for explaining a process at the time of an erroneous call performed by the business phone system of the embodiment. As shown in the upper left corner of FIG. 5, when the outgoing call operation is performed to the IP telephone terminal 3 accommodated in the SIP server 1 (step S1), the IP telephone terminal 3 forms a outgoing call request and passes through the LAN 2. It is transmitted to the SIP server 1 (step S2). When the SIP server 1 receives the outgoing call request from the IP telephone terminal 3, it forms an "INVITE" request (session establishment request), sends it to the wide area network 4, and calls the other party (step S3). ). The "INVITE" request corresponds to the outgoing information sent from the SIP server 1.

After that, the SIP server 1 starts the timekeeping process (time measurement process) (step S4). Further, since the wide area network 4 provides the response code "100 Trying" indicating that the session establishment request is in progress, this is provided to the IP telephone terminal 3 of the outgoing request source through the SIP server 1 (step S5). .. On the other hand, in this embodiment, when the IP telephone terminal 5 of the outside line, which is the destination of the call (the other party of the call), receives the "INVITE" request, the ringing of the incoming call is started (step S6), and the call is being made. The corresponding response code "180 Ringing" is transmitted (step S7). The response code "180 Ringing" is provided to the source IP telephone terminal 3 through the wide area network 4 and the SIP server 1.

In this case, it is assumed that the user of the IP telephone terminal 3 from which the outgoing call is requested notices that he / she has made an erroneous call and performs an on-hook operation (step S8). When the IP telephone terminal 3 receives the on-hook operation, it forms an on-hook notification and notifies the SIP server 1 through LAN 2 (step S9). When the SIP server 1 receives the on-hook notification from the IP telephone terminal 3 of the caller, the SIP server 1 ends the time measurement process (timekeeping process) started in step S4, and determines the measured time (step S10).

After that, the SIP server 1 determines whether or not the measurement time determined in step S10 (the time from sending the INVITE request to receiving the on-hook notification) is within a predetermined time (for example, within 3 seconds) ( Step S11). In the determination process of step S11, it is assumed that the determined measurement time is determined to be within a predetermined time. In this case, it is highly probable that the outgoing call request was an incorrect call. Therefore, the SIP server 1 forms, for example, an apology message "I made a mistake. I'm sorry." And sends this to the other party by the "INFO" request, which is an information notification request in the session (step S12). ). As a result, the apology message is sent to the other party (destination) and provided to the user of the other party.

Further, the SIP server 1 performs a process of adding 1 to the number of wrong calls K (n), and updates this to the "number of mistakes" column of the IP phone terminal 3 of the current originator of the address management DB 104. (Step S13). Here, the character n of K (n) is an integer from 1 to 31 and is information (subscript) indicating a corresponding number storage area in the "number of mistakes" column of the address management DB 104.

After that, the SIP server 1 transmits a "CANCEL" request, which is a session establishment cancellation request, to the IP telephone terminal 5 which is the other party to which the call is made this time through the wide area network 4 (step S14). After that, the SIP server 1 releases the call from the source IP telephone terminal 3 (step S15). As a result, the IP telephone terminal 3 of the call source can make a new call. As shown in FIG. 5 surrounded by a dotted quadrangle, even if the "answer operation" is performed, the call line is not connected because the source IP telephone terminal 3 is on-hook. ..

If the source IP telephone terminal 3 is the other party to whom the call is made after on-hook and the user of the IP telephone terminal 5 performs a response operation, the technique disclosed in Japanese Patent Application Laid-Open No. 2015-46653 is used. It is also possible. That is, when the source IP telephone terminal 3 is the other party who made a call after on-hook and the user of the IP telephone terminal 5 performs a response operation, the response message is provided to the SIP server 1. Therefore, the SIP server 1 can also call the source IP telephone terminal 3 to connect a telephone line and make a call. However, in this case, even immediately after the other party responds and the caller is on-hook, the apology message has already been sent, so the "CANCEL" request is sent without connecting the call line. , The connection process can be canceled.

Further, in the determination process of step S11, it is determined that the determined measurement time is not within the predetermined time, that is, the determined measurement time is longer than the predetermined time. In this case, it is considered that the call was not answered by mistake and the other party was absent or could not answer the call for some reason. Therefore, the apology message was not sent and the normal cancellation process (cancellation of the connection process) was performed. Processing). In this case, since it is desired to make a call with the other party who made the call instead of making a wrong call, the technique disclosed in Japanese Patent Application Laid-Open No. 2015-46653 may be used. That is, when the caller's IP phone terminal 3 is the other party who made a call after on-hook and the user of the IP phone terminal 5 performs a response operation, the caller's IP phone terminal 3 immediately after on-hook is called. , A call line may be connected to make a call.

<Processing with a false call warning>
As shown in step S13 of FIG. 5, the SIP server 1 counts the number of erroneous calls and updates the number of erroneous calls in the "wrong number of times" column of the address management DB 104. Therefore, when there is a call request from the IP telephone terminal 3 having a large number of "errors" using this "number of mistakes", the user is alerted through the IP telephone terminal 3 and an incorrect call is generated. Can be suppressed.

FIG. 6 is a timing chart for explaining other processing at the time of an erroneous call performed by the business phone system of the embodiment. Similar to the case described with reference to FIG. 5, when the outgoing call operation is performed on the IP telephone terminal 3 accommodated in the SIP server 1 (step S1), the IP telephone terminal 3 forms a outgoing call request. It is transmitted to the SIP server 1 through LAN2 (step S2). When the SIP server 1 receives a call request from the IP phone terminal 3, the SIP server 1 refers to the "number of mistakes" column of the source IP phone terminal 3 of the address management DB 104, and determines whether or not the number of mistaken calls during a predetermined period is large. (Step S21). In this embodiment, in the determination process of step S21, for example, it is determined whether or not the number of mistakes in the last 7 days is 5 or more.

In the determination process of step S21, it is assumed that the number of mistakes in the last 7 days is 5 or more (many mistakes). In this case, the SIP server 1 forms a warning message and transmits the alert message to the source IP telephone terminal 3 by the "INFO" request, which is an information notification request in the session (step S22). As mentioned above, this warning message says, "There are many wrong calls. Is the other party's phone number correct? If you like, please press" * ". , And ask for confirmation input through the IP telephone terminal 3.

Therefore, the IP telephone terminal 3 of the calling source accepts the confirmation input (operation input) from the user in response to the instruction from the SIP server 1 (step S23). If the user of the IP telephone terminal 3 determines that the other party to make a call is correct, he / she presses the "*" key, and if he / she determines that the other party is incorrect, he / she performs an on-hook operation. Regardless of which operation is performed, a signal (operation notification) indicating the operation is transmitted from the source IP telephone terminal 3 to the SIP server 1 (step S24).

The SIP server 1 confirms the operation notification from the IP telephone terminal 3 of the calling source, and determines whether or not the "*" key has been operated to instruct the continuation (step S25). When it is determined that the "*" key has not been operated (instructed to continue) in the determination process in step S25 (in the case of "N"), the call from the source IP telephone terminal 3 is released. (Step S26). As a result, the IP telephone terminal 3 of the call source can make a new call.

Further, in the determination process of step S25, when it is determined that the "*" key is operated and the continuation is instructed (in the case of "Y"), as shown in FIG. 6, step S3 shown in FIG. Subsequent call line connection processing is continued. Similarly, in the determination process of step S21, even when it is determined that the number of mistakes in the last 7 days is less than 5 (there are not many mistakes), as shown in FIG. 6, the step shown in FIG. 5 The connection processing of the call line after S3 is continuously performed.

In this way, the SIP server 1 counts the number of erroneous calls and updates the number of erroneous calls in the "wrong number of times" column of the address management DB 104. Therefore, by using this, when a outgoing call request comes from the IP telephone terminal 3 having many erroneous calls, it is possible to call attention and suppress the erroneous call.

[Summary of processing of SIP server 1]
Next, the SIP server 1 of this embodiment having the configuration described with reference to FIG. 2 and having a main role for realizing the processing in the business phone system described with reference to FIGS. 5 and 6 is performed. Summarize the processing. 7 and 8 are flowcharts for explaining the processing at the time of erroneous call performed by the SIP server of the embodiment.

The processes shown in FIGS. 7 and 8 are processes executed by the control unit 102 when a outgoing call request arrives from the subordinate IP telephone terminal 3 connected through the LAN 2. The control unit 102 first controls the error call frequency determination unit 111, refers to the "error number" of the IP telephone terminal 3 that is the source of the address management DB 104 (step S101), and determines whether or not the error number is large. (Step S102). In this embodiment, as described above, for example, it is a process of determining whether or not the number of mistakes in the last 7 days is 5 or more.

In the determination process of step S102, if the error call frequency determination unit 111 determines that the number of errors in the last 7 days is 5 or more (many error calls), this is notified to the alert providing unit 112. do. When the alert providing unit 112 receives the determination result indicating that there are many incorrect calls from the incorrect call frequency determination unit 111, the alert providing unit 112 provides the alert message to the calling IP telephone terminal 3 and requests confirmation input. (Step S103).

After that, the control unit 102 receives the operation notification from the IP telephone terminal 3 of the calling source transmitted through the LAN 2 (step S104), and receives the operation notification instructing the continuation of the connection process of the telephone line by making a call. It is determined whether or not it is present (step S105). It is assumed that in the determination process of step S105, it is determined that the operation notification for making a call and instructing the continuation of the connection process of the telephone line is not accepted. In this case, the control unit 102 performs a process of releasing the call from the source IP telephone terminal 3 (step S106), and ends the process shown in FIGS. 7 and 8.

In the determination process of step S102, if the error call frequency determination unit 111 determines that the number of errors in the last 7 days is not 5 or more (there are not many error calls), the process proceeds to step S107. Further, in the determination process of step S105, if it is determined that the operation notification for instructing the continuation of the connection process of the telephone line has been received by making a call, the process proceeds to step S107. In this case, the control unit 102 controls the transmission control unit 1061 to form an INVITE request (transmission information) and transmit it to call the other party (step S107).

After that, the control unit 102 controls the timer circuit 107 and starts measuring the time after transmitting the INVITE request (step S108). Next, the control unit 102 receives the notification that the on-hook operation has been performed from the source IP telephone terminal 3 (step S109), and determines whether or not the notification that the on-hook operation has been performed has been received. Determine (step S110). It is assumed that in the determination process of step S110, it is determined that the notification that the on-hook operation has been performed has not been accepted. In this case, the control unit 102 receives the response success code (200OK) transmitted by performing the response operation (off-hook operation) at the other party who made the call through the connection end 101T and the communication I / F 101. Whether or not it is determined (step S111).

When it is determined in the determination process of step S111 that the response success code has not been received, the control unit 102 repeats the process from step S109. Further, it is assumed that it is determined that the response success code has been received in the determination process in step S110. In this case, the control unit 102 controls the timer circuit 107 to end the time measurement, and also controls the outgoing call control unit 1061 to connect a telephone line between the calling source IP telephone terminal 3 and the called destination. (Step S112). When the call ends, the connected call line is released and a series of call processing ends. In this way, when the call processing in step S112 is completed, the control unit 102 ends the processing shown in FIGS. 7 and 8.

Further, it is assumed that in the determination process of step S110, it is determined that the notification that the on-hook operation has been performed has been received. In this case, the control unit 102 controls the timer circuit 107, ends the measurement of the time started in step S108, and determines the measurement time (step S113). After this, the control unit 102 proceeds to the process shown in FIG. The control unit 102 controls the wrong telephone determination unit 108 to determine whether or not the time from the transmission of the INVITE request measured by the timer circuit 107 to the on-hook operation is within a predetermined time (for example, within 3 seconds). (Step S114).

It is assumed that the measurement time is determined to be within a predetermined time in the determination process of step S114. In this case, under the control of the control unit 102, the apology message providing unit 109 forms a message (apology message) to the effect that the call is incorrect according to the determination result of the incorrect call determination unit 108, and the other party who made the call. Is transmitted by an INFO request (step S115). After that, the control unit 102 controls the transmission control unit 1061, forms a CANCEL request, transmits the call to the other party who made a call through the wide area network 4, and cancels the connection process of the telephone line (step S116). Finally, the control unit 102 performs a process of releasing the call from the source IP telephone terminal 3 (a process of releasing the connection with the source) (step S117), and the processes shown in FIGS. 7 and 8 are performed. To finish.

Further, it is assumed that the measurement time is not within a predetermined time in the discrimination process in step S114. In this case, the control unit 102 determines whether or not a response success code has been transmitted from the other party who made the call (step S118). It is assumed that in the determination process of step S118, it is determined that the response success code has not been transmitted. In this case, the control unit 102 executes the process from step S116, cancels the connection process of the telephone line (step S116), releases the call from the source IP telephone terminal 3 (step S117), and this figure. 7. The process of FIG. 8 is completed.

Further, it is assumed that it is determined that the response success code has been transmitted in the determination process in step S118. In this case, the control unit 102 performs a process of trying to connect the telephone line (step S119). In step S119, the control unit 102 first controls the transmission control unit 1061 to secure a connection (call path) with the transmission source for a certain period of time. Next, the control unit 102 notifies that the called party has answered by calling the caller's IP phone terminal 3, and when the caller's IP phone terminal 3 answers, the telephone that has already performed the answer operation. Connect the call path (call line) to the other party. After that, in step S119, the control unit 102 determines whether or not the telephone line is connected (step S120).

It is assumed that in the determination process of step S120, it is determined that the telephone line is not connected. In this case, the control unit 102 executes the process from step S116, cancels the connection process of the telephone line (step S116), releases the call from the source IP telephone terminal 3 (step S117), and this figure. 7. The process of FIG. 8 is completed. Further, it is assumed that it is determined that the telephone line is connected in the determination process in step S120. In this case, the control unit 102 controls the call control unit 1061 and executes a call process for connecting a call line between the call source IP telephone terminal 3 and the called party to make a call (step S121). When the call processing is completed, the processing shown in FIGS. 7 and 8 is terminated.

In this way, the SIP server 1 of this embodiment enables an apology message to be provided to the other party even after on-hook when there is a high possibility that the call is a mistake, as a new function related to a mistaken call that has never existed before. ing. In addition, when a call is made from the IP phone terminal 3, which is considered to have many mistaken calls, a function to call attention and suppress mistaken calls is also realized before shifting to the connection processing of the telephone line. ..

In the business phone system of this embodiment, since the SIP server 1 accommodates a plurality of IP telephone terminals 3, the SIP server 1 includes each of the IP telephone terminals 3 accommodated in the own unit, FIG. The processing shown in FIG. 8 can be performed. Further, in the above-described embodiment, the case of making a call from the IP telephone terminal 3 to the external line IP telephone terminal 5 has been described as an example, but the present invention is not limited to the case of making an external line telephone call. Similarly, when making an extension call, it is possible to send an apology message when there is a high possibility that the call is a mistake.

[Effect of Embodiment]
The SIP server 1 of the above-described embodiment makes a call from the subordinate IP phone terminal 3, and the caller's IP phone terminal 3 is on-hook without the other party responding, and there is a possibility that the call is an erroneous call. High cases can be detected. If there is a high probability that the call is a mistake, an apology message can be automatically formed and the other party (destination) can be notified even after the caller's IP phone terminal 3 is on-hooked.

As a result, an apology message is displayed on the display of the other party's telephone terminal. For example, even if the other party hangs up while the user is trying to pick up the call, the apology message is used. , It is possible to prevent the user of the other party from becoming uncomfortable. Therefore, even for the user who made the wrong call, the feeling of guilt that he / she hung up without apologizing even though he / she made the wrong call can be reduced.

In addition, it is possible to grasp the IP telephone terminal 3 having many mistaken telephone calls. As a result, in the case of a call from the IP phone terminal 3 with many mistaken calls, the user of the IP phone terminal 3 is alerted and urged to confirm whether the called party is correct, and the mistake is made. When the confirmation input of no is accepted, the connection process of the call line can be performed. As a result, the occurrence of false calls can be suppressed.

[Modification example]
In the above-described embodiment, it is an erroneous call when the time from the transmission of the INVITE request (outgoing information) until the caller goes on-hook without answering the callee is, for example, within 3 seconds. I tried to distinguish it as a thing. However, this time of 3 seconds or less is an example. For example, it can be set to an appropriate time such as within 5 seconds or within 6 seconds. In this case, a unified predetermined time in the business phone system is set in the non-volatile memory (not shown) in the control unit 102 of the SIP server 1 as a predetermined time as a reference for determining whether or not the call is an erroneous call. Can be done. Further, for example, in the address management DB 104 or the like, it is possible to configure each IP telephone terminal 3 connected to the SIP server 1 to set a predetermined time as a reference for determining whether or not the call is an erroneous call. be.

Further, in the above-described embodiment, an apology is given when the time from the transmission of the INVITE request (outgoing information) to the on-hooking of the caller without the recipient responding is, for example, within 3 seconds. Changed to send a message. On the contrary, when the time from sending the INVITE request (outgoing information) until the caller goes on-hook without answering is longer than a predetermined time, for example, 10 seconds or more. It is also possible to send a message. In this case, for example, it is possible to send a message such as "This is XX. I will call you back later." Or "Please call XX."
