  For example, when there is an incoming call from the caller telephone to the PBX and the PBX rings the extension telephone but the extension telephone does not respond, the PBX transfers to the mobile terminal. The portable terminal that has received the transfer from the PBX displays the telephone number corresponding to the PBX that is the transfer source. Thus, the reason why the transfer destination mobile terminal displays the telephone number corresponding to the transfer source PBX is to comply with the regulations established by the Ministry of Internal Affairs and Communications in order to prevent fraud of the telephone number. However, in this case, it is difficult for the user of the mobile terminal to specify the user of the caller telephone before the call because the number displayed on the mobile terminal is different from the telephone number of the caller telephone.

  In addition, when the mobile terminal is directly called instead of being transferred via PBX in response to a call from the caller telephone, the mobile terminal displays the telephone number of the caller telephone. In this case, the user of the mobile terminal determines whether the call is made from the caller telephone to the user's mobile terminal via the PBX or whether the user's mobile terminal is directly called from the caller telephone without going through the PBX. Difficult to do. Furthermore, when the caller telephone number is not registered in the mobile terminal, it is difficult for the user to specify who the incoming call is from.

  The present invention has been made in view of the above circumstances, and provides an incoming call notification system capable of determining a user of a caller telephone in a user telephone connected to an exchange.

  The incoming call notification system of the first example according to the embodiment includes an exchange, a telephone set, and a server device. The exchange receives a first call from the caller telephone and includes a virtual extension corresponding to the first call. The telephone can communicate with the exchange. The server device can communicate with the exchange and the telephone, and has a first telephone number of the caller telephone and information on the first telephone number. When the exchange receives a first call from the caller telephone, the exchange transmits a first incoming call notification including the first telephone number and the second telephone number of the telephone to the server device in response to the first call. And a second process of making a second call to the virtual extension in response to the first call are executed in parallel, and the telephone corresponding to the second telephone number associated with the virtual extension is Make a call. The server apparatus has a third telephone number corresponding to the exchange, acquires information based on the incoming call notification, and transmits incoming information including the information, the first telephone number, and the third telephone number to the telephone. To do. When the telephone receives the first telephone number or the third telephone number in the third call from the exchange, the telephone displays information included in the incoming call information received from the server device, and in response to the third call When a response from the user is received, a call can be made with the caller telephone.

  The incoming call notification system of the second example according to the embodiment includes an exchange, a telephone set, and a server device. The exchange receives a first call from the caller telephone and includes a virtual extension corresponding to the first call. The telephone can communicate with the exchange. The server device can communicate with the exchange and the telephone, and has a first telephone number of the caller telephone and information on the first telephone number. When the exchange receives the first call from the caller telephone, the exchange receives a first process of sending an incoming call notification including the first telephone number to the server device in response to the first call, and the first call In response, a second process for making a second call to the virtual extension is executed in parallel, and a third call is made to the telephone corresponding to the second telephone number associated with the virtual extension. When the telephone receives a third call from the exchange, the telephone requests the server device to transmit incoming information. When the telephone receives the first telephone number from the exchange in the third call, the telephone transmits the first telephone number to the server device. When the server device is requested to transmit incoming information from the telephone, the server device acquires information based on the incoming notification received from the exchange or the first telephone number received from the telephone, and the incoming information including the information is transmitted to the telephone. Send. The telephone displays information included in the incoming call information received from the server device, and when a response is received from the user in response to the third call, the telephone is ready to communicate with the caller telephone.

That is, the incoming call information D2 manages information for specifying the user of the caller telephone 30 corresponding to the telephone number of the caller telephone 30. The content of the incoming call information D2 is not limited to this, and can be modified as appropriate.

  The operation of the above configuration will be described.

The incoming call notification system 10 includes a notification-type approach (first operation mode) from the CTI device 61 to the first telephone 41 as a mobile terminal, and an inquiry-type approach (second operation) from the first telephone 41 to the CTI device 61. Operation mode). The notification type approach and the inquiry type approach may be selectively used depending on the characteristics of the OS installed in the first telephone 41. When the OS or the program P1 accesses the CTI device 61 from the first telephone 41, the OS or the program P1 can switch between the notification-type approach and the inquiry-type approach, and may transmit an approach switching instruction to the CTI device 61. In this case, the CTI device 61 switches between the notification-type approach and the inquiry-type approach in response to a switching instruction from the first telephone set 41.
(First embodiment)
(Notification approach)
In the notification-type approach from the CTI device 61 to the first telephone 41 as a mobile terminal, an incoming call to the PBX is transmitted to a fixed extension telephone, but the extension telephone is not responding and is transferred to the mobile terminal (transfer) There is a case where the mobile terminal is directly called based on an incoming call to the PBX (referred to as a direct call operation).
(Transfer call operation)
First, with reference to FIG. 6, a transfer call operation for transferring an incoming call to a fixed extension telephone to a portable terminal will be described.

  It is assumed that nothing is registered in the contact recording unit 415 provided in the first volatile memory 41c in the first telephone 41 for the sake of simplification of explanation. Further, the first telephone 41 can use any of public line connection, FMC connection, and IP connection.

  The first telephone 103a activates a program P1 that can communicate with the CTI device 61, establishes a TCP level connection with the CTI device 61, and performs an authentication process using user-specific identification information and a password. After the authentication, the first telephone 103a makes a permanent socket connection to the CTI device 61 by the program P1, and maintains a communication state between the program P1 of the first telephone 103a and the CTI device 61. That is, the program P1 in the first telephone 103a monitors the permanent socket connection with the CTI device 61, and spontaneously reconnects when the connection is disconnected. Further, the program P1 transmits a command for designating which of the notification type approach and the inquiry type approach is used to the CTI device 61. In response to this command, the program P2 of the CTI device 61 switches operation.

  In the above state, when the telephone number of the PBX 20 is transmitted from the caller telephone 30 (step S11) and the PBX 20 receives an incoming call (step S12), the PBX 20 transmits an incoming call notification to the CTI device 61 (step S13a). This incoming call notification includes the telephone number of the caller telephone 30 such as “03-1111-1111”, the name of the caller, and the callee telephone number “03-5000-0001”.

  Further, for example, in response to a request from the user of the caller telephone 30, the PBX 20 transmits an incoming call notification to the second telephone 42 as an extension telephone and calls the second telephone 42 (step S13b).

  When receiving the incoming call notification from the PBX 20, the CTI device 61 acquires (searches) the incoming call information D2 in the data server 62 based on the incoming call notification (step S14), and receives the incoming call information corresponding to the telephone number of the caller telephone 30; For example, a company name is acquired (step S15).

  The CTI device 61 notifies the first telephone 41 of the acquired company name, the telephone number of the caller telephone 30, and the telephone number of the PBX 20 (information indicating that the call is received via the PBX 20) (step S16).

  When the connection between the CTI device 61 and the first telephone 41 is disconnected, the CTI device 61 sends the company name, the telephone number of the caller telephone 30 and the telephone of the PBX 20 to the notification server 63 shown in FIG. The number (incoming number) is transmitted, and from the notification server 63, the company name, the telephone number of the caller telephone 30 and the telephone number of the PBX 20 are transmitted to the first telephone 41.

  The first telephone 41 stores the telephone number and company name of the caller telephone 30 in the contact recording unit 415 of the first volatile memory 41c shown in FIG. 2 corresponding to the telephone number of the PBX 20 (step S17).

  Specifically, two contacts are stored in the contact recording unit 415 of the first volatile memory 41c. That is, as the first contact information, for example, in correspondence with the telephone number “03-5000-0001” of the PBX 20, the telephone number “03-1111-1111” of the calling telephone 30 and the company name “TA Corporation” Is stored in the contact recording unit 415 of the first volatile memory 41c.

  Further, as the second contact information, for example, the telephone number “03-1111-1111” of the caller telephone 30 and the company name “TA Corporation” are stored in the contact recording unit 415 of the first volatile memory 41c. Is done.

  On the other hand, when the second telephone 42 called in step S13 does not respond (step S18), the PBX 20 acquires the telephone number of the mobile terminal corresponding to the extension number based on the exchange information D1, for example, The incoming call is transferred to the first telephone 41 by the telephone number, and the first telephone 41 is called (step S19).

  When an incoming call occurs, the first telephone 41 receives the telephone number “03-5000-0001” of the PBX 20 stored as the first contact in the contact recording unit 415 of the first volatile memory 41c, The telephone number “03-1111-1111” of 30 and the company name “TA Corporation” are displayed on the display device 41e (step S20).

  FIG. 7A shows an example of display on the first telephone 41. On the display device 41e, the telephone number “03-5000-0001” of the PBX 20, the company name “TA Corporation”, and the telephone number “03-1111-1111” of the caller telephone 30 are displayed. Therefore, the user of the first telephone 41 can recognize that this incoming call has been transferred via the PBX 20.

  Further, an operation button 41h is displayed on the display device 41e.

  Thereafter, when a response is instructed by operating the operation button 41h displayed on the display device 41e, the first telephone set 41 and the caller telephone set 30 are connected and a call can be made (step S21).

  The first telephone set 41 is stored in the contact recording unit 415 of the first volatile memory 41c when the call with the caller telephone set 30 is finished (step S22) and a predetermined time elapses. Of the eye information, for example, the telephone number of the PBX 20 "03-5000-0001" and the telephone number "03-1111-1111" of the caller telephone 30 are deleted (step S23).

  If the incoming call information of the caller is not registered in the data server 62 and the company name of the caller cannot be acquired in step S15, the first telephone 41 sets the display device 41e in step S20. You may display the content different from the content displayed by. Specifically, for example, the first telephone 41 may acquire information related to incoming information from a Web network such as a cloud and display this information on the display device 41e.

  The incoming call information shown in step S23 may be erased at any timing after the start of the call, during the call, or after the end of the call. Further, the incoming call information may be erased automatically by the first telephone 41 or by the user at an arbitrary timing.

In FIG. 6 described above, the processing from when the PBX 20 transmits an incoming notification to the CTI device 61 until the CTI device 61 transmits incoming information to the first telephone 41 (S13a, S14, S15, S16), and the PBX 20 The processing from calling the second telephone 42 to calling the first telephone 41 (S13b, S18, S19) may be executed in parallel. Specifically, for example, the PBX 20 may transmit the incoming call notification to the CTI device 61 and call the second telephone 42 almost simultaneously. Alternatively, for example, the PBX 20 may transmit the incoming call notification to the CTI device 61 and call the first telephone 41 almost simultaneously. In other words, the call control of the PBX 20 and the processing of the CTI device 61 may be executed in parallel.
(Direct call operation)
Next, with reference to FIG. 8, in the notification-type approach from the CTI device 61 to the first telephone 41 as the mobile terminal, a direct call operation for directly calling the mobile terminal in response to an incoming call to the PBX 20 will be described.

  In FIG. 8, the operation from step S11 to S17 is almost the same as the transfer call operation. That is, when the PBX 20 receives a call from the caller telephone 30 (steps S11 and S12), the PBX 20 transmits an incoming call notification to the CTI device 61 (step S13a).

  The CTI device 61 acquires the incoming call information D2 in the data server 62 based on the incoming call notification, and acquires, for example, the company name corresponding to the telephone number of the caller telephone 30 (step S15).

  The CTI device 61 notifies the first company 41 of the acquired company name, the telephone number of the caller telephone 30, and the telephone number of the PBX 20 (step S16).

  The first telephone 41 stores the telephone number and company name of the caller telephone 30 in the contact recording unit 415 of the first volatile memory 41c shown in FIG. 2 corresponding to the telephone number of the PBX 20 (step S17).

  On the other hand, the PBX 20 receives a call from the caller telephone 30 and, for example, when the telephone number of the first telephone 41 corresponding to the extension number is designated, calls the first telephone 41 directly (step S13c).

  When an incoming call occurs, the first telephone 41 receives the telephone number “03-1111-1111” of the caller telephone 30 stored as the first contact in the contact recording unit 415 of the first volatile memory 41c, The company name “TA Corporation” is displayed on the display device 41e (step S20).

  FIG. 7B shows an example of display on the first telephone 41. On the display device 41e, the company name of the transmission source “TA Inc.” and the telephone number “03-1111-1111” of the transmission source telephone 30 are displayed. For this reason, the user of the first telephone 41 is, for example, that the call is from a caller that is not registered in the first telephone 41 and that the caller is displayed via the PBX 20 by displaying the caller. It is possible to recognize that the PBX 20 has directly called the first telephone 41 without transfer.

  Further, for example, in the case of an incoming call via the PBX 20, the display device 41 e indicates that the incoming call is via the PBX 20, for example, by displaying the telephone number or extension number of the PBX 20 in a different form from the transfer case. Display information. Thus, the user of the first telephone 41 can recognize whether the incoming call is via the PBX 20 or the incoming call is made directly by the first telephone 4 without going through the PBX 20.

  Thereafter, when a response is instructed by operating the operation button 41h displayed on the display device 41e, the first telephone set 41 is connected to the caller telephone set 30 and is ready for a call (step S21).

  For example, the first telephone 41 is stored in the contact recording unit 415 of the first volatile memory 41c when the call with the caller telephone 30 ends and a predetermined time elapses (step S22). For example, the telephone number “03-5000-0001” of the PBX 20 and the telephone number “03-1111-1111” of the caller telephone 30 are deleted (step S23).

  In FIG. 8 described above, the processing (S13a, S14, S15, S16) from when the PBX 20 transmits an incoming call notification to the CTI device 61 until the CTI device 61 transmits incoming call information to the first telephone 41, and the PBX 20 The process of calling the first telephone 41 (S13c) may be executed in parallel. Specifically, for example, the PBX 20 may transmit the incoming call notification to the CTI device 61 and call the first telephone 41 almost simultaneously. In other words, the call control of the PBX 20 and the processing of the CTI device 61 may be executed in parallel.

  According to the first embodiment, when there is an incoming call to the PBX 20, the CTI device 61 acquires incoming information from the data server 62 and transmits it to the first telephone 41, and the first telephone 41 as a portable terminal. When there is an incoming call from the PBX 20, the incoming call information notified from the CTI device 61 is displayed on the display device 41e before starting a call with the caller telephone 30. For this reason, the user of the first telephone 41 can recognize the user of the caller telephone 30 even in the case of a transfer call from the PBX 20 and in the case of a non-transfer direct call from the PBX 20. Therefore, the user of the first telephone 41 can start a call with the user of the caller telephone 30 after recognizing the user of the caller telephone 30.

  According to the first embodiment, whether the user of the first telephone 41 is an incoming call via the PBX 20 or is an incoming call in which the first telephone 4 is directly called without going through the PBX 20, Can be recognized.

The incoming call information stored in the data server 62 is acquired by the CTI device 61 and notified to the first telephone (portable terminal) 41 regardless of the operation of the PBX 20. For this reason, it is not necessary to change the function of PBX20 and it is possible to use existing PBX.
(Second Embodiment)
(Inquiry type approach)
Next, an inquiry type approach from the CTI device 61 to the first telephone 41 as a portable terminal will be described. In the case of the notification type approach, the contact recording unit 415 provided in the first volatile memory 41c in the first telephone 41 is included. However, in the case of the inquiry type approach, the contact recording unit 415 is omitted. Is possible.

In the inquiry type approach, there are a transfer call operation and a direct call operation.
(Transfer call operation)
First, the transfer call operation will be described with reference to FIGS.

  In the transfer call operation of the inquiry type approach shown in FIG. 9, the operations from step S11 to S15 are almost the same as the notification type approach. In the case of the notification-type approach, the incoming call information acquired by the CTI device 61 is spontaneously transmitted to the first telephone 41 by the CTI device 61. On the other hand, in the case of the inquiry type approach, the incoming information acquired by the CTI device 61 is transmitted to the first telephone 41 after a transmission request is sent from the first telephone 41.

  Specifically, when the PBX 20 receives a call from the caller telephone 30 and calls the second telephone 42 and does not answer, the PBX 20 calls the first telephone 41 (S13b, S18, S19).

  When receiving the call from the PBX 20, the first telephone 41 displays the telephone number “03-5000-0001” of the PBX 20 transmitted from the PBX 20 on the display device 41e (S31).

  FIG. 10A shows a state in which the telephone number “03-5000-0001” of the PBX 20 is displayed on the display device 41e. Thereby, the user of the first telephone 41 can recognize that the company extension telephone has been transferred by the PBX 20. However, at this time, it cannot be recognized who the incoming call is.

  Thereafter, the first telephone 41 requests the CTI device 61 to transmit incoming information (step S32). That is, the first telephone 41 requests transmission of incoming call information corresponding to the incoming call number “03-5000-0001”.

  The CTI device 61 transmits the incoming call information corresponding to the incoming call number “03-5000-0001” acquired in step S15 to the first telephone set 41 (step S33).

  The first telephone 41 displays the incoming call information transmitted from the CTI device 61 on the display device 41e (step S34).

  FIG. 10B shows a state in which, for example, the extension number “200” and the source information “TA Co., Ltd.” are displayed on the display device 41e as the incoming call information. From the displayed incoming call information, the user of the first telephone 41 can recognize that this incoming call has been transferred from the extension number 200 and that the caller is “TA TA Corporation”.

  Thereafter, when a response is instructed by operating the operation button 41h displayed on the display device 41e, the first telephone 41 is connected to the caller telephone 30 and is ready to talk (step S21).

In FIG. 9 described above, the processing from when the PBX 20 transmits an incoming notification to the CTI device 61 until the CTI device 61 receives the incoming information from the data server 62 (S13a, S14, S15), and the PBX 20 is the second telephone. The process from calling 42 to calling the first telephone 41 (S13b, S18, S19) may be executed in parallel. Specifically, for example, the PBX 20 may transmit the incoming call notification to the CTI device 61 and call the second telephone 42 almost simultaneously. Alternatively, for example, the PBX 20 may transmit the incoming call notification to the CTI device 61 and call the first telephone 41 almost simultaneously. In other words, the call control of the PBX 20 and the processing of the CTI device 61 may be executed in parallel.
(Direct call operation)
Next, the direct call operation of the inquiry type approach will be described with reference to FIGS.

  In the direct call operation of the inquiry type approach shown in FIG. 11, the operations from steps S11 to S13a, S14, and S15 are the same as the direct call operation of the inquiry type approach. Also in this case, the incoming call information acquired by the CTI device 61 is transmitted to the first telephone 41 after a transmission request is transmitted from the first telephone 41.

  On the other hand, when the telephone number of the first telephone 41 corresponding to the extension number is designated with the incoming call from the caller telephone 30, the PBX 20 calls the first telephone 41 directly (step S13c).

  When there is an incoming call from the PBX 20, the first telephone 41 displays the telephone number (caller's telephone number) “03-1111-1111” of the caller telephone 30 transmitted from the PBX 20 on the display device 41e (S41). ).

  FIG. 12A shows a state where the telephone number “03-1111-1111” of the caller telephone 30 is displayed on the display device 41e. As a result, the user of the first telephone 41 can recognize that an outside line call has been received. However, since the telephone number information is not registered in the first telephone 41, the information of the caller telephone 30 is not displayed on the display device 41e. Therefore, at this time, the user of the first telephone 41 cannot recognize whether the call has been made directly from the PBX 20 or an outside line has been made without going through the PBX 20.

  Thereafter, the first telephone 41 requests the CTI device 61 to transmit incoming information (step S42). That is, the first telephone 41 transmits the incoming call number “03-1111-1111” to the CTI device 61 and requests the incoming call information corresponding to this incoming call number.

  The CTI device 61 transmits the incoming call information corresponding to the incoming call number “03-1111-1111” acquired in step S15 to the first telephone set 41 (step S43).

  The first telephone 41 displays the incoming call information transmitted from the CTI device 61 on the display device 41e (step S44).

  FIG. 12B shows a state where, for example, the caller's telephone number “03-1111-1111” and the caller's information “TA Co., Ltd.” are displayed on the display device 41e as the incoming call information. By switching the displayed incoming information and display, the user of the first telephone set 41 recognizes that the incoming call is transmitted from the PBX 20 and that the caller is “TA Corporation”. it can.

  Further, the first telephone 41 displays this information when the incoming information includes information indicating that it is an incoming call via the PBX 20, for example. As a result, it is possible to recognize information indicating whether the incoming call is via the PBX 20 or whether the first telephone 4 is called directly without going through the PBX 20.

  Thereafter, when a response is instructed by operating the operation button 41h displayed on the display device 41e, the first telephone set 41 is connected to the first telephone set 30 and is ready for a call (step S21).

  In FIG. 11 described above, the processing from when the PBX 20 transmits an incoming notification to the CTI device 61 until the CTI device 61 receives the incoming information from the data server 62 (S13a, S14, S15), and the PBX 20 is the first telephone. The process of calling 41 (S13c) may be executed in parallel. Specifically, for example, the PBX 20 may transmit the incoming call notification to the CTI device 61 and call the first telephone 41 almost simultaneously. In other words, the call control of the PBX 20 and the processing of the CTI device 61 may be executed in parallel.

  According to the second embodiment, the first telephone (portable terminal) 41 receives a call from the PBX 20 directly to the CTI device 61 before starting a call with the caller telephone 30 after being called directly without transfer. Information transmission is requested, and the incoming call information notified from the CTI device 61 is displayed on the display device 41e. Therefore, the user of the first telephone (portable terminal) 41 can recognize the user of the caller telephone 30 even in the case of a transfer call from the PBX 20 and in the case of a direct call by non-transfer from the PBX 20. it can. Therefore, the user of the first telephone 41 can start a call with the user of the caller telephone (caller telephone) 30 after recognizing the user of the caller telephone 30.

  According to the first embodiment, whether the user of the first telephone 41 is an incoming call via the PBX 20 or is an incoming call in which the first telephone 4 is directly called without going through the PBX 20, Can be recognized.

Also, in the second embodiment, the incoming information stored in the data server 62 is acquired by the CTI device 61 and notified to the first telephone (portable terminal) 41. For this reason, it is not necessary to change the function of PBX20 and it is possible to use existing PBX.
(Third embodiment)
In the third embodiment, a modified example of the first and second embodiments will be described.

  The first telephone 41 stores the incoming call information in the contact recording unit 415 (step ST17).

  Since the virtual extension V does not respond in step ST13b (step ST18), the PBX 20 acquires the telephone number CC corresponding to the virtual extension V based on the exchange information Da, for example, and receives the incoming call to the first telephone set 41 by this telephone number CC. And the first telephone 41 is called (step ST19).

  When an incoming call occurs, the first telephone 41 displays the incoming call information stored in the contact recording unit 415 on the display device 41e (step ST20).

  In FIG. 16, when the first telephone 41 receives a call from the external telephone connected to the public network via the PBX 20, the first telephone 41 receives the PBX telephone number “03-5000-0001” from the PBX 20. receive. The first telephone 41 can display information related to the telephone number of the caller telephone 30 by searching and displaying incoming information including the PBX telephone number “03-5000-0001”.

  When the first telephone 41 receives a call from the extension telephone via the PBX 20, the first telephone 41 receives the telephone number “03-1111-1111” of the caller telephone 30 from the PBX 20. The first telephone 41 can display information related to the caller telephone 30 by searching and displaying incoming call information including the telephone number “03-1111-1111” of the caller telephone 30.

  In this way, the first telephone set 41 can realize information display regardless of whether it is called from an outside line or an extension line.

  Thereafter, when a response instruction is given to the first telephone set 41, the first telephone set 41 and the caller telephone set 30 are connected, and a call can be made (step ST21).

  The first telephone set 41 erases part or all of the incoming information stored in the contact recording unit 415 when the call with the caller telephone set 30 is finished (step ST22) and a predetermined time has elapsed. (Step ST23).

  The incoming call information shown in step ST23 may be erased at any timing after the call starts, during a call, or after the call ends. Further, the incoming call information may be erased automatically by the first telephone 41 or by the user at an arbitrary timing.

  FIG. 17 is a second sequence chart showing the operation of the incoming call notification system according to the third embodiment. The operation shown in FIG. 17 is an operation suitable for realizing the notification-type approach in the incoming call notification systems 10B and 10B shown in FIGS. In FIG. 17, step ST18 in FIG. 16 is deleted, and in parallel (almost simultaneously) with the call to the virtual extension V (step ST13b) without waiting for the notification that the virtual extension V is not responding. 1 is called (step ST19).

  Accordingly, in the operation of FIG. 17, the PBX 20 transmits an incoming call notification to the CTI device 61 (step S13a), calls the virtual extension (step ST13b), and calls the first telephone 41 (step ST19). Run in parallel.

  FIG. 18 is a third sequence chart illustrating the operation of the incoming call notification system according to the third embodiment. The operation of FIG. 18 is an operation suitable for the case where the inquiry type approach is realized by the incoming call notification system 10A of FIG. In FIG. 18, the second telephone set 42 shown in FIG. 9 is replaced with a virtual extension V.

  When the PBX 20 receives a call from the caller telephone 30 and calls the virtual extension V and does not answer, the PBX 20 calls the first telephone 41 (ST11, ST13b, ST18, ST19).

  In FIG. 18, the incoming call notification transmitted from the PBX 20 to the CTI device 61 includes the telephone number “03-1111-1111” of the caller telephone 30 and the telephone number “090-9000-9000” of the first telephone 41 to be called. ”. However, the telephone number “090-9000-9000” of the first telephone 41 to be called does not have to be included in the incoming call notification.

  When receiving the call from PBX 20, first telephone 41 displays the telephone number “03-5000-0001” of PBX 20 transmitted from PBX 20 on display device 41e (ST31). Thereby, the user of the first telephone 41 can recognize that the company extension telephone has been transferred by the PBX 20. However, at this time, it cannot be recognized who the incoming call is.

  Thereafter, the first telephone 41 requests the CTI device 61 to transmit incoming information (step ST32).

  In FIG. 18 described above, when the first telephone 41 receives a call from the extension telephone via the PBX 20, the first telephone 41 receives the telephone number “03-1111-1111” of the caller telephone 30 from the PBX 20.

  Further, when the first telephone 41 receives a call from the external telephone connected to the public line network via the PBX 20, the first telephone 41 receives the PBX telephone number “03-5000-0001” from the PBX 20.

  For example, when the first telephone 41 requests the CTI device 61 to transmit incoming call information and receives the telephone number “03-1111-1111” of the caller telephone 30 from the PBX 20, the first telephone 41 receives the call received from the PBX 20. The telephone number “03-1111-1111” of the original telephone 30 is transmitted to the CTI device 61.

  For example, when the first telephone 41 requests the CTI device 61 to transmit incoming call information and receives the PBX telephone number “03-5000-0001” from the PBX 20, the first telephone 41 receives the PBX telephone number “03” received from the PBX 20. -5000-0001 "is transmitted to the CTI device 61.

Da to Dc may be read out.

  In the incoming call notification systems 10A to 10B according to the third embodiment described above, the CTI device 61 is communicably connected to the PBX 20, and the CTI device 61 receives an incoming call notification from the PBX 20. The incoming notification includes, for example, the telephone number of the source telephone 30 and the telephone number of the first telephone 41 that is the destination. As a result, the CTI device 61 can recognize the transmission source and the transmission destination, and obtains incoming information about the transmission source from the data server 62.

  The incoming call information may include, for example, a caller telephone number, a caller name (for example, company name, department name, name, etc.), information indicating that the call is made via the PBX 20, and other information related to the caller. .

  In the notification-type approach, when the virtual extension V of the PBX 20 is called from the caller telephone 30, the CTI device 61 transmits the incoming information to the first telephone 41 having the extension number associated with the virtual extension V. Telephone 41 receives and displays the incoming call information.

  In the inquiry-type approach, when the virtual extension V of the PBX 20 is called from the calling telephone 30, the first telephone 41 having the extension number associated with the virtual extension V makes an inquiry about incoming information to the CTI device 61. In response to the inquiry, the CTI device 61 transmits the incoming information to the first telephone 41 having the extension number associated with the virtual extension V, and the first telephone 41 receives and displays the incoming information.

  In the third embodiment, the PBX 20 first receives an incoming call from the caller telephone 30 via the virtual extension V, so that the telephone number can be made uniform, and the setting and switching of the telephone in the extension to be called can be performed. Can be easily performed.

  In the third embodiment, the first telephone set 41 stores (registers) incoming information received from the CTI device 61. This incoming information includes, for example, the telephone number of the caller telephone 30, the telephone number of the first telephone 41 to be called, the PBX telephone number corresponding to the telephone number of the first telephone 41 to be called, Contains information about phone numbers. As a result, when the first telephone 41 receives a call by an external telephone connected to the public line network, the first telephone 41 obtains information on the telephone number of the caller telephone 30 in response to the call by the PBX telephone number. Can be displayed. When the first telephone 41 receives a call through an extension telephone, the first telephone 41 can display information related to the telephone number of the caller telephone 30 in response to a call by the telephone number of the caller telephone 30. Accordingly, the first telephone set 41 can handle calls from either outside lines or extensions.

  In the incoming call notification systems 10A to 10C according to the third embodiment, the virtual extension V is called, and then the first telephone 41 is called. However, in an environment where the virtual extension V cannot be used, the same control as the above-described incoming call notification systems 10A to 10C may be realized using an extension corresponding to a physical device instead of the virtual extension V.
