  The terminal device 11 is connected to the Internet network 3 constituting the local communication network 8, the Internet network 2 constituting the public communication network 9, and a public switched telephone network (hereinafter referred to as “PSTN network”) 5. Has been. The terminal device 11 can communicate via the Internet networks 2 and 3 and the PSTN network 5. The server 21 is connected to the Internet network 2 and the PSTN network 5 that constitute the public communication network 9. The server 21 is in a state where communication can be performed via the Internet network 2 and the PSTN network 5. The extension terminal 31 can be connected to both the Internet network 3 constituting the local communication network 8 and the Internet network 2 constituting the public communication network 9. The extension terminal 31 can make a call by connecting to the Internet networks 2 and 3. The communication device 51 can be connected to the PSTN network 5 constituting the public communication network 9. The communication device 51 can make a call by connecting to the PSTN network 5.

  The extension terminal 31 is a call terminal for making a call using the inside of the Internet network 3 constituting the specific local communication network 8 as a communication infrastructure. The extension terminal 31 is equipped with a WLAN (Wireless Local Area Network) communication means, and is connected to the Internet network 3 wirelessly. Further, the extension terminal 31 is not limited to the Internet network 3, and can be connected to the Internet network 2 of the public communication network 9 to make a call. The extension terminal 31 performs wireless communication with an access point (not shown) connected to the Internet networks 2 and 3 and is connected to the Internet networks 2 and 3. Therefore, outside the service area where the access point can communicate, it is impossible to make a call by connecting to the Internet networks 2 and 3. As the extension terminal 31, for example, a wireless SIP (Session Initiation Protocol) can be used.

  The communication device 51 is a call terminal that connects to the PSTN network 5 constituting the public communication network 9 and makes a call. As the communication device 51, a conventionally known mobile phone or PHS can be used.

  The terminal device 11 is provided in the local communication network 8. In the terminal device 11, the extension terminal 31, communication device 51, and other call terminals (hereinafter referred to as “transmission source terminal”) that desire a call, and the extension terminal 31 and communication device 51 (hereinafter “transmission”) of the other party that desires the call. Call data transfer processing with respect to the “destination terminal”) is executed. As a result, a call can be performed between the transmission source terminal and the transmission destination terminal. The server 21 is provided in the public communication network 9. In the server 21, as with the terminal device 11, call data transfer processing between the transmission source terminal and the transmission destination terminal is executed. Here, the call data refers to data necessary for a call between the transmission source terminal and the transmission destination terminal, and includes call data, incoming call permission data, incoming call rejection data, and in-call data. Details of these data will be described later.

  An outline of a call data transfer method executed in the terminal device 11 and the server 21 will be described. When a person who desires a call (referred to as a “caller”) starts a call with a call partner (referred to as a “receiver”) that owns the extension terminal 31, first, from the sender terminal owned by the caller Data for calling the telephone terminal (hereinafter referred to as “calling data”) is transmitted to the extension terminal 31 owned by the called party. The call data includes at least an ID for specifying the extension terminal 31.

  When the call data is received by the terminal device 11, the ID is referred to and it is determined whether or not the extension terminal 31 exists within a callable area. Here, the callable area means a place where communication with an access point (not shown) is possible. Since the extension terminal 31 is connected to the Internet networks 2 and 3 by radio, it may not be connected to the Internet networks 2 and 3 depending on the surrounding environment. In particular, when the extension terminal 31 is taken out of the local area communication network 8, the probability of being out of service area is high.

  When it is determined that the extension terminal 31 exists within the callable area, the terminal device 11 transfers the call data to the extension terminal 31. When the extension terminal 31 permits the call, the call is started between the transmission source terminal and the extension terminal 31.

  On the other hand, when the extension terminal 31 does not exist within the callable area or the call is rejected at the extension terminal 31, the terminal device 11 stores the communication device 51 previously associated with the extension terminal 31 and stored. Is referenced. Then, the call data is transferred to the referenced communication device 51. Then, when the communication device 51 permits the call, the call is started between the transmission source terminal and the communication device 51. Thus, even if the extension terminal 31 does not exist within the communicable area and the caller cannot communicate with the callee via the extension terminal 31, the caller can communicate with the communication device. It is possible to make a call with the callee via the call 51.

The status is updated when an area notification is received from the extension terminal 31 (details will be described later). In the example illustrated in FIG. 7, for example, ID “0000001”, status “online”, and status update date and time “2008/8/8 20:01” are stored. This information indicates that the extension terminal 31 with the ID “0000001” exists within a communicable area and the status has been updated to “2008/8/8 20:01”.

  Note that status information having the same configuration as described above is also stored in the status storage area 1502 of the data storage unit 15 of the terminal device 11. Detailed description is omitted.

  Details of the transfer destination information stored in the transfer destination storage area 2503 of the data storage unit 25 of the server 21 will be described with reference to FIG. FIG. 8 is a schematic diagram showing details of transfer destination information stored in the transfer destination storage area 2503.

  As shown in FIG. 8, the transfer destination information includes information items of ID, transfer destination telephone number, company flag, home flag, mobile phone flag, and priority. In the ID, an ID for specifying each extension terminal 31 is stored. In the transfer destination telephone number, the telephone number of the transfer destination communication device 51 is stored for each ID. The company flag, the home flag, and the mobile flag are flag information used when the priority order of the transfer destination is changed. In the example illustrated in FIG. 8, when “TRUE” is stored as flag information, the priority order of the corresponding communication device 51 is increased to “1”. When “FALSE” is stored, the priority order of the corresponding communication device 51 is not changed, or is sequentially lowered as another priority order is changed. In the priority order, when the call data is transferred to the communication device 51, the priority order when there are a plurality of transfer destination communication devices 51 is stored.

  Each flag information will be described in detail. The “company flag” is referred to when there is a high possibility that the called party is enrolled in the company. Accordingly, the priority of the communication device 51 is set to “1” by setting the company flag of the communication device 51 (for example, an in-house common call terminal) capable of making a call with the recipient who is in the company to “TRUE”. Since it is moved up, the possibility of making a call with the callee increases. The “home flag” is referred to when there is a high possibility that the callee is already at home. Accordingly, by setting the home flag of the communication device 51 (for example, a home phone) that can communicate with the called party at home to “TRUE”, the priority of the communication device 51 is raised to “1”. The possibility of making a call with the callee increases. The “mobile phone flag” is referred to when there is a high possibility that the callee is on the way home. Therefore, the priority of the communication device 51 is set to “1” by setting the portable flag of the communication device 51 (for example, a mobile phone owned by the recipient) that can talk to the called party on the way home to “TRUE”. Since it is moved up, the possibility of making a call with the callee increases.

  For example, in the example shown in FIG. 8, the ID “0000002”, the transfer destination telephone number “090-9999-2222”, the company flag “FALSE”, the home flag “FALSE”, the mobile phone flag “FALSE”, and the priority “1” are stored. Has been. In addition, an ID “0000002”, a transfer destination telephone number “052-824-1111”, a company flag “TRUE”, a home flag “FALSE”, a mobile phone flag “FALSE”, and a priority “2” are stored. Further, ID “0000002”, transfer destination telephone number “090-9999-4444”, company flag “FALSE”, home flag “FALSE”, portable flag “TRUE”, and priority “3” are stored. This information includes "090-9999-2222" (priority order "1"), "052-824-1111" (priority order "2" as the transfer destination telephone number of the extension terminal 31 specified by the ID "0000002". )) And “090-9999-4444” (priority order “3”) are registered. Further, when the priority is changed and the company flag is referred to, the priority corresponding to the transfer destination telephone number “052-824-1111” in which the company flag is “TRUE” is higher. The priority is raised ("2" → "1"), and the other priorities are successively lowered. When the mobile phone flag is referred to, the transfer destination telephone number “090-9999-4444” having the mobile phone flag “TRUE” is moved up (“3” → “1”), and another priority order is set. Are decremented sequentially.

  Each process executed by the CPU 22 of the server 21 will be described with reference to the flowcharts of FIGS. 9 and 10. FIG. 9 is a flowchart of the area confirmation processing. FIG. 10 is a flowchart of the call transfer process. The area confirmation processing is started and executed by the CPU 22 when the server 21 is powered on. The call transfer process is activated and executed by the CPU 22 of the server 21 when call data is received from the transmission source terminal.

  The area confirmation processing will be described with reference to FIG. As shown in FIG. 9, in the area confirmation process, first, it is determined whether or not an area notification has been received from the extension terminal 31 and the terminal device 11 (S11). The area notification is data for presence notification transmitted from the extension terminal 31. In order to notify that the extension terminal 31 is within a communicable range, the extension terminal 31 transmits a range notification at a constant cycle (see S103, FIG. 13, described later). When the extension terminal 31 exists within a communicable area, the in-area notification is transmitted to the server 21 via the Internet networks 2 and 3. The server 21 determines whether or not the extension terminal 31 exists within a communicable area depending on whether or not the area notification is received. In addition, when the terminal device 11 receives the notification of the coverage area, the notification of the coverage area is transferred to the server 21 (S63, see FIG. 11, described later). Thereby, the server 21 collectively manages the area information of the extension terminals 31.

  When the notification of the area is received (S11: YES), it is determined that the extension terminal 31 that has transmitted the notification of the area exists in the area where the call can be made. Then, the status information stored in the status storage area 2502 of the data storage unit 25 is updated (S13). Specifically, the status corresponding to the ID of the extension terminal 31 that transmitted the in-zone notification in the status information is set to “online”. In addition, the current date and time are stored in the corresponding status update date and time. Next, a registration completion notification for notifying that the update process has been completed is transmitted to the extension terminal 31 that has transmitted the in-zone notification (S14). Then, the process proceeds to S17. On the other hand, when no area notification is received from any extension terminal 31 (S11: NO), the process proceeds to S17 without performing any special process.

  In S17, the status update date and time in the status information is compared with the current date and time. Then, an elapsed time after the status information is updated is calculated (S17). Here, when the calculated elapsed time is equal to or longer than the predetermined time (S17: YES) and it is determined that the predetermined time has elapsed since the status information was last updated, the corresponding extension terminal 31 It is determined that the notification has not been received for a long time. In such a case, the status of the corresponding extension terminal 31 is set to “offline” (S19). Then, the process proceeds to S11, and the above process is repeatedly executed. On the other hand, when the calculated elapsed time is less than the predetermined time (S17: NO), the process returns to the process of S11 without performing any special process, and the above process is repeatedly executed.

  By executing the above processing, the server 21 can recognize whether or not the extension terminal 31 exists within a communicable area. The status information is referred to when the call data is transferred to the extension terminal 31 (details will be described later).

  The call transfer process will be described with reference to FIG. As shown in FIG. 10, in the call transfer process, first, the status information stored in the status storage area 2502 is referred to based on the ID included in the received call data (S21). Then, it is determined whether or not the extension terminal 31 specified by the ID (hereinafter referred to as “called extension terminal”) is within a callable area (S23).

  When the status corresponding to the ID of the called extension terminal is “online” and it is determined that the called extension terminal exists within a communicable area (S23: YES), the calling data is sent to the called extension terminal. Transferred (S31). Then, the process proceeds to S39.

  On the other hand, if the status corresponding to the ID of the called extension terminal is “offline” and it is determined that the called extension terminal does not exist within the callable range (S23: NO), the transfer destination storage area 2503 is loaded. The stored transfer destination information is referenced. Specifically, the forwarding telephone number corresponding to the ID included in the call data is searched. If a plurality of corresponding transfer destination telephone numbers are stored, the transfer destination telephone numbers are selected in descending order of priority associated with the ID (S29). When it is determined that at least one transfer destination telephone number corresponding to the ID is stored and there is a communication device (hereinafter referred to as “called communication device”) to which the call data is transferred (S33: YES). In order to transfer the call data to the selected called communication device, the call data is transmitted to the transfer destination telephone number (S37). Then, the process proceeds to S39.

  In S39 to 45, a response from the called extension terminal or called communication device that has received the call data is monitored. When the call is rejected by the called extension terminal or the called communication device that has received the call data, an incoming call rejection notification is transmitted from the called extension terminal or the called communication device (S116, see FIG. 14, described later). . When the server 21 receives the incoming call rejection notification (S39: YES), it is determined that the called extension terminal or called communication device has rejected the call. In this case, the process returns to S29 in order to transmit the call data to another communication device stored in the transfer destination storage area 2503.

  If the incoming call rejection notification is not received (S39: NO), it is determined whether the called extension terminal or the called communication device that has received the call data is busy. When a call is in progress, the called extension terminal or the called communication device transmits a busy notification to the call data (S113, see FIG. 14, described later). When the server 21 receives a busy notification from the called extension terminal or the called communication device (S41: YES), it is determined that the called extension terminal or the call is in progress and the call cannot be made. In this case, the process returns to S29 in order to transmit the call data to another communication device stored in the transfer destination storage area 2503.

  When the notification during the call is not received (S41: NO), the elapsed time from the transmission of the calling data in S37 is monitored (S43). If the elapsed time is equal to or longer than the predetermined time (S43: YES), it is determined that the called extension terminal or the called communication device is in a state where a call cannot be made. In this case, the process returns to S29 in order to transmit the call data to another communication device stored in the transfer destination storage area 2503.

  When it is determined that the called extension terminal or the called communication device that has transmitted the calling data is in a state where the call cannot be made, the called communication that cannot be called based on the transfer destination information stored in the transfer destination storage area 2503 Communication devices other than devices are repeatedly selected in descending order of priority (S29, S33). In a state where there is a communication terminal that has not transmitted call data (S33: YES), call data transfer processing for the repeatedly selected called communication device is executed (S37).

  In a state where the elapsed time from the transmission of the call data is less than the predetermined time (S43: NO) and no notification is received from the called extension terminal or the called communication device (S45: NO), S39 Returning to the process, the above-described response monitoring is repeatedly executed (S39 to S45).

  On the other hand, when a call is permitted by the called extension terminal and the called communication device that have received the call data, a call permission notification is transmitted from the permitted called extension terminal or the called communication device ( S118, see FIG. 14, described later). When this call permission notice is received in a state where the elapsed time from the transmission of the call data is less than the predetermined time (S43: NO) (S45: YES), the call with the called extension terminal or the called communication device Is determined to be possible. In this case, voice data for a call is transmitted, and a call is performed between the transmission source terminal and the called extension terminal or called communication device (S47). During this time, the end of the call is monitored (S49: NO). If the end of the call is detected (S49: YES), this process ends.

  When the call data is transmitted to all the transfer destination telephone numbers registered in the transfer destination information and no call permission notice can be received from any of the communication devices (S33: NO) The extension number information stored in the extension number storage area 2501 is referred to. Then, a mail address corresponding to the ID of the called extension terminal is selected, and a mail for notifying that there is an incoming call is transmitted to this mail address (S35). Then, this process ends.

  As described above, when the server 21 is in a state where a call with the called extension terminal is not possible, the server 21 transmits the calling data to the communication device registered along with the called extension terminal. As a result, the caller can make a call via another communication device when the called extension terminal does not exist within a communicable area or cannot call.

  Each process executed by the CPU 12 of the terminal device 11 will be described with reference to the flowcharts of FIGS. 11 and 12. FIG. 11 is a flowchart of the area confirmation processing. FIG. 12 is a flowchart of the call transfer process. The area confirmation process is started and executed by the CPU 12 when the terminal device 11 is powered on. The call transfer process is started and executed by the CPU 12 of the terminal device 11 when call data is received from the transmission source terminal.

  It should be noted that within-range confirmation processing and call transfer processing executed by the CPU 12 of the terminal device 11 described below, and within-range confirmation processing (see FIG. 9) and call transfer processing (see FIG. 10) executed by the CPU 22 of the server 21. ) The description overlapping with) is omitted or simplified.

  The area confirmation processing will be described with reference to FIG. As shown in FIG. 11, in the area confirmation process, it is determined whether or not an area notification has been received from the extension terminal 31 (S61). When the notification of the area is received (S61: YES), first, the received notification of the area is transferred to the server 21 (S63). Next, the status information stored in the status storage area 1502 of the data storage unit 15 is updated (S65). Specifically, the status corresponding to the ID of the extension terminal 31 that transmitted the in-zone notification in the status information is set to “online”. In addition, the current date and time are stored in the corresponding status update date and time. Then, the process proceeds to S67. On the other hand, when the notification of the area is not received (S61: NO), the process proceeds to S67 without performing any special process.

  In S67, the status update date and time in the status information is compared with the current date and time, and the elapsed time after the status information is updated is calculated (S67). Here, when the calculated elapsed time is equal to or longer than the predetermined time (S67: YES), the status of the corresponding extension terminal 31 is set to “offline” (S69). Then, the process proceeds to S61, and the above process is repeatedly executed. On the other hand, when the calculated elapsed time is less than the predetermined time (S67: NO), the process returns to the process of S61 without performing any special process, and the above process is repeatedly executed.

  By executing the above processing, the terminal device 11 can collectively manage whether or not the extension terminal 31 exists within a communicable area. The terminal device 11 itself can also manage status information.

  The call transfer process will be described with reference to FIG. As shown in FIG. 12, in the call transfer process, first, the status information stored in the status storage area 1502 is referred to based on the ID included in the received call data (S71), and is specified by the ID. It is determined whether or not the called extension terminal exists within a communicable area (S73). If the status corresponding to the ID of the called extension terminal is “online” and it is determined that the called extension terminal exists within a communicable area (S73: YES), a call is made to the called extension terminal. Data is transferred (S81). Then, the process proceeds to S91.

  When the status corresponding to the ID of the called extension terminal is “offline” and it is determined that the called extension terminal does not exist within the callable area (S73: NO), the server 21 is accessed and the data storage unit 25 is accessed. Status information stored in the status storage area 2502 is acquired (S75). Then, the acquired status information is referred to, and it is determined whether or not the called extension terminal specified by the ID exists within a communicable area (S77). When the status corresponding to the ID of the called extension terminal is “online” and it is determined that the called extension terminal exists within the communicable area (S77: YES), the calling data is sent to the called extension terminal. Transferred (S81). Then, the process proceeds to S91.

  On the other hand, regardless of whether the status information stored in the status storage area 1502 or the status information acquired from the server 21 is referenced, the status corresponding to the ID of the called extension terminal is “offline”, and the called When it is determined that the extension terminal does not exist within the communication range (S77: NO), the server 21 is accessed, and the transfer destination information stored in the transfer destination storage area 2503 of the data storage unit 25 is acquired. (S79). Then, the acquired transfer destination information is referred to. Then, among the transfer destination telephone numbers corresponding to the ID included in the call data, the transfer destination telephone numbers are searched in descending order of priority (S81). When the transfer destination telephone number corresponding to the ID is stored and it is determined that the called communication device exists (S83: YES), the transfer is performed to transfer the call data to the called communication device. The calling data is transmitted to the destination telephone number (S87). Then, the process proceeds to S91.

  In S91 to 97, a response from the called extension terminal or called communication device that has received the call data is monitored. When the call is rejected by the called extension terminal or the called communication device that has received the call data and the incoming call rejection notification is received (S91: YES), the transfer destination information acquired from the server 21 is referred to for other communication. In order to transmit the call data to the device, the process returns to S81.

  Further, when a call with the called extension terminal or called communication device is in progress and a call notification is received (S91: NO, S93: YES), the transfer destination information acquired from the server 21 is referred to, and the like. In order to transmit the call data to the communication device, the process returns to S81.

  In addition, when the elapsed time after the call data is transmitted (S87) is equal to or longer than the predetermined time (S93: NO, S95: YES), the transfer destination information acquired from the server 21 is referred to, and other communication devices In order to transmit the call data to the process, the process returns to S81.

  When it is determined that the called extension terminal or the called communication device that has transmitted the call data is in a state where it is not possible to make a call, the transfer destination communication terminals are repeated in descending order of priority based on the transfer destination information acquired from the server 21. Search is performed (S81, S83). When there is a communication terminal that does not transmit call data (S83: YES), call data transfer processing is repeatedly executed (S87).

  If the elapsed time from the transmission of the call data is less than the predetermined time (S95: NO) and no notification is received from the called extension terminal or the called communication device (S97: NO), This process ends.

  On the other hand, when a call permission notification is received in a state where the elapsed time from the transmission of the call data is less than a predetermined time (S95: NO) (S97: YES), the call with the called extension terminal or the called communication device Is determined to be possible. In this case, voice data for a call is transferred, and a call is performed between the transmission source terminal and the called extension terminal or called communication device (S99). During this time, the end of the call is monitored (S100: NO). When the end of the call is detected (S100: YES), this process ends.

  When the call data is transmitted to all the transfer destination telephone numbers registered in the transfer destination information acquired from the server 21, and the call permission notification cannot be received from any of the communication devices. (S83: NO), the extension number information stored in the extension number storage area 1501 is referred to. Then, a mail address corresponding to the ID of the called extension terminal is selected, and a mail for notifying that there is an incoming call is transmitted to this mail address (S85). Then, this process ends.

  As described above, when the terminal device 11 cannot communicate with the called extension terminal, the terminal device 11 transmits the calling data to the communication device registered with the called extension terminal. . As a result, when the called extension terminal does not exist within the communicable range or cannot communicate, it is possible to make a call via another communication device.

  With reference to FIG. 13, the service area notification process executed by the extension terminal 31 will be described. FIG. 13 is a flowchart of the area notification process. The area notification process is activated and executed by the CPU 12 when the extension terminal 31 is powered on.

  As shown in FIG. 13, in the in-range notification process, it is first determined whether or not the user is in a communicable range (S101). Specifically, it is transmitted from an access point (not shown) at a constant cycle. If it is possible to receive a beacon, it is determined that the user is within a communicable area. If it is determined that the user does not exist within the communicable range (S101: NO), the process returns to S101 without performing any special processing, and it is monitored whether or not the user is within the communicable range. The

  If it is determined that the user is within a communicable area (S101: YES), an intra-area notification for notifying that the user is within a communicable area is transmitted (S103). The transmitted coverage notification is received by the terminal device 11 and the server 21 via the Internet networks 2 and 3.

  Next, the process waits until a registration completion notification transmitted from the server 21 is received (S105: NO). When the server 21 receives the service area information, the server 21 stores the information in the status information and transmits a registration completion notification for notifying that the registration of the status information is completed to the extension terminal 31 (S14, FIG. 9). When the extension terminal 31 receives this registration completion notification (S105: YES), it determines that its own area information has been registered in the server 21.

  Next, it waits until the next in-range notification transmission cycle arrives (S107: NO). When it is determined that the transmission cycle has passed and the transmission cycle of the in-range notification has arrived (S107: YES), the process returns to S101, and the above-described notification process is repeatedly executed.

  With reference to FIG. 14, a call process executed by the extension terminal 31 and the communication device 51 will be described. FIG. 14 is a flowchart of call processing. The call process is started and executed by the CPU 32 when the extension terminal 31 is powered on. Further, when the communication device 51 is powered on, it is activated and executed by the CPU 52.

  As shown in FIG. 14, in the call process, first, a call data reception monitoring process is performed (S111). If the call data is not received via the wireless communication module (S111: NO), the process returns to S111, and the call data reception monitoring process is repeatedly executed.

  If reception of call data is detected (S111: YES), it is then determined whether or not it is already in a call with another call terminal (S112). When the call is in progress (S112: YES), since the call cannot be made with the transmission source terminal that has transmitted the call data, the call notification for notifying the transmission source terminal that the call is in progress Is transmitted (S113). Then, the process returns to S111 and the above-described processing is repeatedly executed.

  If the call is not in progress (S112: NO), since the call origination is requested from the transmission source terminal, a bell is ringed (S114) to notify the callee that there is an incoming call.

  When an incoming call rejection operation is performed by the called party (S115: YES), an incoming call rejection notice for notifying that the incoming call cannot be received is transmitted to the transmission source terminal (S116). Then, the process returns to S111 and the above-described processing is repeatedly executed. Even if the incoming call is not rejected (S115: NO), if the call start operation is not performed (S117: NO), the process returns to S114 and the bell is continuously ringed. Then, the user is prompted to perform some operation.

  When an incoming operation is performed by the recipient (S117: YES), a communication permission notification for notifying that the incoming operation is performed and the call is started is transmitted to the transmission source terminal (S118). Then, the exchange of the call voice is started with the transmission source terminal, and the call is started (S119). During a call, the end of the call is continuously monitored (S120: NO). If the call termination operation is performed by the called party (S120: YES), the process for terminating the call is performed, and then the process returns to S111 and the above-described process is repeatedly executed.

  As described above, in the terminal device 11 and the server 21, when it is determined that the extension terminal 31 does not exist within a callable area, or when it is determined that the extension terminal 31 is in a state where the call cannot be made. The call data is transferred to the associated communication device 51. As a result, even when a call cannot be made via the extension terminal 31, it becomes possible to make a call via the communication device 51.

  In addition, when there are a plurality of communication devices 51 associated with the extension terminal 31, the terminal device 11 and the server 21 select the communication device 51 in descending order of priority set for each communication device 51, Call data is transferred to the selected communication device 51. As a result, it is possible to preferentially select a communication device capable of making a call and transfer the call data.

  In addition, this invention is not limited to the said embodiment and modification, A various change is possible.

In the present invention, the communication device 51 to be selected is specified based on the priority order of the transfer destination information stored in the transfer destination storage area 1503 of the terminal device 11 and the transfer destination storage area 2503 of the server 21, and the communication data is transferred. Was. However, the present invention is not limited to this specific method. For example, the priority order of the transfer destination information may be changed based on the presence information of the extension terminal 31, and the communication device 51 may be selected based on the changed priority order. Hereinafter, modifications of the present embodiment will be described.
<Modification>

  Hereinafter, modifications of the present invention will be described with reference to FIGS. 15 and 16. FIG. 15 is a flowchart of a call transfer process in the modification. FIG. 16 is a subroutine flowchart of the priority order changing process. In the call transfer process in the modification, the priority order of the transfer destination information stored in the transfer destination storage area 2503 in the data storage unit 25 of the server 21 is changed in the priority order change process (S131) according to the state of the called party. Processing is performed. Since other processes are the same as the call transfer process (see FIG. 10), the description is omitted or simplified.

  The call transfer process will be described with reference to FIG. After the call data is received and activated, status information is acquired (S21). Then, when it is determined that the called extension terminal is in a state where it cannot talk (S23: NO, or S23: YES, S39: NO, S41: NO, S43: YES), the priority order changing process is executed ( S131). Then, after the priority order changing process, a call destination communication device as a transfer destination is selected based on the changed priority order (S29, S33), and calling data is transmitted to the selected called communication device ( S37).

  The priority order changing process will be described with reference to FIG. As shown in FIG. 16, in the priority order changing process, it is first determined whether or not the called extension terminal exists within a communicable area (S133). At the time of determination, the status of status information stored in the status storage area 2502 of the server 21 is referred to.

  When the status corresponding to the ID of the called extension terminal is “online” and it is determined that the called extension terminal exists within a communicable area (S133: YES), the called extension terminal is Then, after the call data is transferred, it is determined that a notification indicating that a call cannot be made is received from the call data. In such a case, the called party is likely to still be present at the company. Accordingly, a call can be made when the call data is transferred to a transfer destination telephone number in which the company flag of the transfer destination information is “TRUE” among the transfer destination telephone numbers stored in the transfer destination storage area 2503. It is determined that there is a high possibility of entering a state. Therefore, the priority order associated with the transfer destination telephone number is increased to “1”, and the priority orders associated with the remaining transfer destination telephone numbers are sequentially decreased (S135). Then, the priority order changing process ends.

  On the other hand, if the status corresponding to the ID of the called extension terminal is “offline” and it is determined that the called extension terminal does not exist within the communicable area (S133: NO), the callee returns home. It is determined that there is a high possibility that Therefore, next, the status update date and time associated with the ID of the called extension terminal in the status information is referred to. Then, the elapsed time from the update date to the current date is calculated. This elapsed time is the time after the status becomes “offline” and the called extension terminal moves out of the communicable area. Then, based on this elapsed time, priority order change processing is executed.

  If the calculated elapsed time is 2 hours or more (S137: YES), it is highly likely that the callee has already arrived at the home because a considerable time has passed since the callee left the company. It is judged. Therefore, a call can be made when call data is transferred to a transfer destination telephone number in which the home flag of the transfer destination information is “TRUE” among the transfer destination telephone numbers stored in the transfer destination storage area 2503. It is determined that there is a high possibility of entering a state. Therefore, the priority order associated with the transfer destination telephone number is increased to “1”, and the priority orders associated with the remaining transfer destination telephone numbers are sequentially decreased (S139). Then, the priority order changing process ends.

  On the other hand, if the calculated elapsed time is less than 2 hours (S137: NO), it is likely that the time has not passed since the callee left the company and that he / she is on his way home. To be judged. Therefore, a call can be made when call data is transferred to a transfer destination telephone number whose transfer destination information form flag is “TRUE” among transfer destination telephone numbers stored in the transfer destination storage area 2503. It is determined that there is a high possibility of entering a state. Therefore, the priority order associated with the transfer destination telephone number is incremented to “1”, and the priority orders associated with the transfer destination telephone number are sequentially decreased (S141). Then, the priority order changing process ends.

  Note that the above-described priority change process is performed when it is determined in the call transfer process (see FIG. 12) executed by the terminal device 11 that the called extension terminal is in a state where a call cannot be made (S77: NO, or S91: NO, S93: NO, S95: YES, see FIG. Then, after the priority order changing process, a transfer destination called communication device is selected based on the changed priority order (S81, S83, see FIG. 12), and calling data is sent to the selected called communication device. It is transmitted (S87, see FIG. 12). Detailed description is omitted.

  As described above, in the priority order changing process, the status of the called party is determined based on the elapsed time since the extension terminal 31 has moved from the communicable area to the outside area, and the priority order is changed. As a result, it is possible to preferentially select the communication device 51 that is more likely to be called by the called party and transmit the calling data, so that it is possible to reliably call the called party.
