The subscriber data registration means assigns a high reliability level to the subscriber data registered from the management terminal, and is registered by the first PBX subscriber data registration method. A medium reliability level is assigned to the subscriber data, and a low reliability level is assigned to the subscriber data registered by the second PBX subscriber data registration method. And it shall be granted.

  In this way, the reliability level of each extension telephone number registered as a subscriber is used for priority control at the time of call control, and the reliability level is notified to the terminal of the other party, so that It is possible to provide a material for judging reliability.

  Also, the first PBX system according to the present invention is characterized in that the uniqueness of the subscriber data registered in the subscriber database by the first PBX subscriber data registration method or the second PBX subscriber data registration method. The mobile phone terminal or the PC registered as a subscriber is used as an extension telephone terminal using the IP address of the mobile phone and the mobile phone number or the telephone number of the existing telephone terminal.

  In this way, for example, a mobile phone terminal that cannot be used due to a large-scale disaster, etc., and an extension telephone service using a PC that replaces the existing telephone terminal can be quickly provided by the newly installed PBX system. can do.

  Further, the second PBX system according to the present invention provides a call sent from the extension telephone terminal to a special number in the first PBX system using the mobile phone terminal or the PC as the extension telephone terminal. A special number database for associating the special number with the extension telephone number for receiving any one of the one or more extension telephone terminals in which an extension telephone number is registered in advance for each of the special numbers; A plurality of the extension telephone numbers corresponding to the same special number registered in the telephone number are assigned an arrival order, and when a call sent to each of the special numbers is received, an incoming call priority control is executed according to the incoming order. To do.

  In this way, for example, even in a disaster area where a telephone becomes unavailable due to a large-scale disaster or the like, an extension telephone service using a PBX system that newly installs a special number service such as an emergency telephone can be provided.

  The third PBX system according to the present invention is the first PBX system that uses the mobile phone terminal or the PC as the extension telephone terminal. The call control server of the PBX system is the extension telephone terminal. A call history database that records the call history of calls destined for an external telephone terminal from the extension telephone terminal in correspondence with the extension telephone number of the extension telephone terminal and the external telephone number of the external telephone terminal. The extension telephone number of the connection destination is acquired from the external telephone terminal, and the transmission history addressed to the external telephone number of the external telephone terminal is acquired from the extension telephone terminal of the acquired extension telephone number. The call is received at the extension telephone terminal of the extension telephone number on the condition that it is recorded in the database.

  In this way, only the call made from the external telephone terminal that received the call from the extension telephone terminal is received by the extension telephone terminal that originated the call. For example, congestion due to concentration of visiting calls in the disaster area, etc. Can be prevented, and telephone communication between users in the disaster area and external users can be facilitated.

  The fourth PBX system according to the present invention is the first PBX system using the mobile phone terminal or the PC as the extension telephone terminal. The call control server of the PBX system is the extension telephone terminal. A call history database that records the call history of calls destined for an external telephone terminal from the extension telephone terminal in correspondence with the extension telephone number of the extension telephone terminal and the external telephone number of the external telephone terminal. The extension telephone of the extension telephone terminal that made the call to the external telephone number by searching the outgoing call history addressed to the external telephone number of the external telephone terminal recorded in the outgoing call history database. Get the number, announce the acquired extension telephone number by voice, acquire the extension telephone number selection information from the external telephone terminal, select The was assumed to incoming the call to the extension telephone terminal of the telephone extension.

  By doing this, a known telephone number that has been used in the past is announced to the outside telephone terminal of the caller as an extension telephone number of the extension telephone terminal that has made a call to the terminal. For example, when an external telephone terminal that receives a call from an extension telephone terminal in a disaster area makes a return call, it is easy to specify the extension telephone terminal to be connected.

  The fifth PBX system according to the present invention is the first PBX system that uses the mobile phone terminal or the PC as the extension telephone terminal. The call control server of the PBX system is the extension telephone terminal. A call history database in which the call history of calls addressed to an external phone terminal is associated with the extension telephone number of the extension phone terminal and the external phone number of the external phone terminal, and records the presence or absence of a response to a return call for each call When a call from an external telephone terminal is received, the outgoing call history addressed to the external telephone number of the external telephone terminal recorded in the outgoing call history database is searched to make a call to the external telephone number The extension telephone number of the extension telephone terminal that performed the call is acquired, and the return call is received among the acquired extension telephone numbers. Response by is assumed to incoming the call to the extension telephone terminal of the extension telephone number corresponding to the newest the outgoing call history is not recorded.

  In this way, for example, when an external telephone terminal that has received a call from a plurality of extension telephone terminals in the affected area makes a return call, it takes precedence over the extension telephone terminal of the other party that has not yet made a call by the return call. Therefore, it is possible to make it easier to contact a plurality of users who have transmitted from the disaster area.

  According to the present invention, for example, subscriber data registration to a PBX system temporarily installed in a disaster area or the like can be speeded up, and a telephone service can be provided early. Further, even when an outside line telephone terminal makes a return call using the incoming call history from the extension telephone terminal accommodated in the PBX system, it is possible to easily connect to the extension telephone terminal of the transmission source.

DESCRIPTION OF EMBODIMENTS Hereinafter, embodiments for carrying out the present invention will be described in detail with reference to the drawings as appropriate.
FIG. 13 is an explanatory diagram illustrating an example in which a communication path in a disaster area is blocked due to a large-scale disaster or the like. In normal times, the mobile phone terminal 3 such as a smartphone is connected to another mobile phone terminal 3, a fixed phone terminal 5a, or an IP (Internet Protocol) phone terminal 4b via the nearest mobile phone base station 71 and the mobile phone network 7. , 5b. Similarly, the fixed telephone terminal 5a is connected to the telephone switching center 81 and the public telephone network 8 in which the subscriber line is accommodated, and the IP telephone terminals 4b and 5b are connected to the IP relay station 91 and the access line. A call can be made with other telephone terminals 3, 4, 5 via the IP network 9.

  Here, as indicated by the crosses in FIG. 13, all functions of the mobile phone base station 71, the telephone exchange 81, and the IP relay station 91 installed in the disaster area A have been lost due to a large-scale disaster or the like. Think about the case. At this time, not only between the telephone terminals 3, 4, 5 in the disaster area A and the telephone terminals 3, 4, 5 in other places, but also between the telephone terminals 3, 4, 5 in the disaster area A , You won't be able to make any calls.

  Therefore, in order to restore the telephone service as soon as possible in such a situation, the local government or the like uses a mobile switching center 1 using a temporary PBX system as an emergency measure value as shown in FIG. It has been considered that an existing mobile phone terminal 3 or a general-purpose PC (Personal Computer) 4 in the disaster area A can be used as an extension telephone terminal by bringing it into the disaster area A and constructing a temporary LAN 2.

  FIG. 1 is an explanatory diagram showing a schematic configuration of a temporary PBX system using a PBX system according to the present invention installed as a mobile switching center 1. When a temporary PBX system is constructed using a conventional (commercially available) PBX system, the configuration is the same as this, and the mobile switching center 1 installed in the disaster area has a public telephone network 8 and a gateway 6 via a gateway 6. Connected to the IP network 9. In the temporary LAN 2, the mobile switching center 1 and each device are wiredly connected by a HUB 21 and a LAN cable, or wirelessly connected via a wireless LAN base station (access point) 22.

  However, in the conventional PBX system, the registration operation of the subscriber information (terminal body identification number of the terminal, extension telephone number to be assigned, IP address, etc.) of the terminal newly accommodated as an extension telephone terminal is performed with expert knowledge and registration authority. It is necessary for an SO (Service Order) registrant to have a sufficient amount of time to secure the personnel and complete the work. On the other hand, the PBX system according to the present invention eliminates the work of the SO registrant by enabling subscriber registration by the user's own operation of the telephone terminal, as will be described later with reference to FIG. Therefore, a telephone service using the existing mobile phone terminal 3 or the general-purpose PC 4 can be provided at an early stage.

  FIG. 2 is an explanatory diagram showing an outline of a subscriber registration method for the PBX system according to the present invention. In a disaster or the like, a telephone terminal that can be accommodated in the PBX system according to the present invention requires a function for making a call using IP communication and a subscriber registration function for the IP-PBX system. As shown in FIG. 2, when the target telephone terminal is a mobile phone terminal 3 such as a smartphone, the IP-PBX registration function unit 31 having a subscriber registration function has a dedicated application program (in the figure, a dedicated application program and (Abbreviated) is previously installed in the terminal. Further, when the general-purpose PC 4 is newly used as a telephone terminal, the IP-PBX registration function unit 41 is realized by a general-purpose Web browser. Therefore, a URL (Uniform Resource Locator) of a Web page that provides the function. The address only needs to be registered in the storage unit in advance. As application programs for making a call using IP communication, IP-Phone 32 and IP-Phone 42 are installed in advance, respectively.

  The subscriber information registration receiving unit 17 preinstalled as a control program of the subscriber registration server 16 is a subscriber registration request transmitted from the mobile phone terminal 3 or the PC 4 and a subscriber registration request input from the management terminal 12. The request is transferred to the subscriber information registration management unit 14 that is preinstalled as a control program for the IP-PBX server 11. The subscriber information registration management unit 14 adds the subscriber information included in the received subscriber registration request to the subscriber database 13 and stores it. Although not shown, the IP-PBX server 11 includes a transmission history database 18 and a special number database 19 as will be described later.

  When newly registering a subscriber to the temporary PBX system 1 at the time of a disaster or the like, the user of the target telephone terminal performs a predetermined operation, whereby the respective IP-PBX registration function units 31 and 41 are performed. Is activated. Accordingly, the IP-PBX registration function units 31 and 41 connect the terminal to the temporary LAN 2 to acquire the IP address used by the terminal, and register the acquired IP address and the extension telephone number as its own IP address. A subscriber registration request including the phone number unique to the terminal is transmitted to the subscriber registration server 16 via the temporary LAN 2. The subscriber information registration receiving unit 17 of the subscriber registration server 16 that has received the request transfers the received subscriber registration request to the IP-PBX server 11 that performs call control, and subscribes to the IP-PBX server 11 that has received the request. The subscriber information registration management unit 14 registers the correspondence data between the IP address and the extension telephone number in the subscriber database 13 to complete the subscriber registration.

  At this time, when the target telephone terminal is the mobile phone terminal 3, the unique telephone number transmitted by the IP-PBX registration function unit 31 as the registered extension telephone number is the SIM installed in the terminal. (Subscriber Identity Module) The registered mobile phone number read from the card 33 is used. As a result, the mobile phone number unique to the terminal is registered as it is in the temporary PBX system 1 as the extension telephone number of the terminal, so that manual input by the user is not required and subscriber registration can be easily performed. . Further, it is possible to prevent erroneous input of phone numbers and false registration. Further, other users other than the user of the terminal can improve the convenience of the service because the telephone number of the call destination that has been used before becomes the extension telephone number as it is.

  Further, when the general-purpose PC 4 is newly used as a telephone terminal, the user of the terminal accesses a specific URL address from the Web browser so that the subscriber information registration receiving unit 17 of the subscriber registration server 16 can access it. The function of the IP-PBX registration function unit 41 is provided. As a result, the IP-PBX registration function unit 41 has a unique telephone number (a fixed telephone number, an IP telephone number, or a mobile telephone number of a mobile telephone terminal that cannot be used as an extension telephone terminal) that has been used by the user. The subscriber registration request including the inputted telephone number is transmitted to the subscriber registration server 16.

  FIG. 3 is a configuration example of a subscriber database in which subscriber information is registered. As shown in FIG. 3, the subscriber record registered in each row of the subscriber database 13 includes fields of MAC (Media Access Control) address, IP address, extension telephone number, reliability level, registration date and time, and registration password. It is configured. Here, the MAC address is a unique address in the world that is assigned in advance to each communication port installed in the apparatus. In the extension telephone number, any one of the mobile telephone number, fixed telephone number, and IP telephone number included in the subscriber registration request is registered. The reliability level will be described later with reference to FIG. In the registration date and time, the registration date and time of the subscriber record is recorded. The registration password is an arbitrary character string that needs to be input when updating or deleting the subscriber record, and is specified when the user performs a subscriber registration operation.

  The call control unit 15 (see FIG. 2), which is installed in advance as a control program for the IP-PBX server 11, performs processing of a call connection request received via an extension telephone terminal connected to the temporary LAN 2 or the gateway 6. The telephone terminal which is designed to refer to the subscriber database 13 and whose telephone number unique to the extension telephone number of the subscriber database 13 is registered and registered as a subscriber is immediately subject to the extension telephone service. Become. Therefore, extension telephone calls using the IP-Phones 32 and 42 mounted on both terminals can be performed between the extension telephone terminals that have completed subscriber registration.

  FIG. 4 is an explanatory diagram of the reliability level registered in the subscriber database. In the example of FIG. 4, five levels from “1” to “5” are provided as reliability levels of registered subscriber information. The reliability level “5” with the highest reliability is a telephone number registered by an IP-PBX administrator (such as a local government) and is highly public. For example, a telephone number of a fire department, police, government office, etc. The reliability level “4” is a telephone number registered by an IP-PBX administrator (such as a local government) after confirming the reliability. The reliability level “3” has little room for falsification, such as a telephone number automatically read from a SIM card or the like of a mobile phone terminal. The reliability level “2” indicates that the telephone number has been received and the uniqueness and validity of the telephone number has been confirmed. The reliability level “1” having the lowest reliability is a telephone number based solely on self-reporting by the user. The reliability level of each telephone number is used for priority control during call control, and the reliability level of the other party is provided to the user by notifying the reliability level to the called terminal. Can do.

  FIG. 5 is a sequence diagram of the subscriber registration operation to the PBX system according to the present invention. When a predetermined operation for switching a telephone terminal whose communication path during normal operation is interrupted due to a disaster or the like to the operation mode at the time of a disaster is performed, a connection operation from the telephone terminal to the temporary LAN 2 is first executed. . If the target telephone terminal can be connected to the wireless LAN, the IP telephone can be connected to the temporary LAN 2 wirelessly via the wireless LAN base station (access point) 22 and the target telephone terminal can only be wired. In the case of 4b, PC4a, etc., connection to the temporary LAN 2 is performed via a temporary LAN cable or the HUB 21.

  At this time, the target IP telephone terminal first notifies its own MAC address to a DHCP (Dynamic Host Configuration Protocol) server (not shown) that manages the IP address of the terminal connected to the temporary wireless LAN 2. A connection request to the LAN is made (step S51). The DHCP server accepts the connection request, issues one IP address to be assigned, and notifies the IP telephone terminal of it (step S52). The telephone terminal that has received the notification of the IP address can subsequently communicate with other terminals connected to the temporary LAN 2 by using the IP address. Next, the IP telephone terminal requests the DNS (Domain Name System) server (not shown) whose address is notified from the DHCP server to resolve the name of the server name of the temporary PBX system set in the storage unit in advance. (Step S53), and notification of the IP addresses of the subscriber registration server 16 and the IP-PBX server 11 is received from the DNS server (Step S54). Then, the IP telephone terminal uses the notified IP address to add the subscriber registration server 16 (not shown in FIG. 5) to its own MAC address, IP address, unique telephone number, registration password, etc. A registration request is transmitted (step S55). Finally, the IP-PBX server 11 receives the registration request via the subscriber registration server 16 that has received this subscriber registration request, and after confirming the duplicate registration of the number and determining the reliability level, After additionally registering a subscriber record in the subscriber database 13, a series of subscriber registration operations are completed by notifying the IP telephone terminal of the registration result (step S56).

  In addition, TCP / IP (Transmission Control Protocol / Internet Protocol) communication such as HTTP (HyperText Transfer Protocol) can be used for communication between the IP telephone terminal and the subscriber registration server 16 or the IP-PBX server 11. .

  FIG. 6 is a sequence diagram of an outgoing call operation from an extension telephone terminal (IP telephone terminal) registered as a subscriber. First, a call request is sent from the extension telephone terminal to the IP-PBX server 11 (step S61), and a response to the call request acceptance is returned from the IP-PBX server 11 (step S62). Next, the destination telephone number is transmitted from the extension telephone terminal (step S63). The IP-PBX server 11 searches the subscriber database 13 for a subscriber record having the received destination telephone number as an extension telephone number, thereby calling the destination telephone terminal (extension) via the LAN, and An IP address is acquired (step S64). Subsequently, the IP-PBX server 11 calls the destination telephone terminal using the acquired MAC address and IP address (step S65), and when a response is returned from the destination telephone terminal (step S65). S66), the extension telephone terminal of the transmission source and the telephone terminal of the transmission destination are connected to each other by extension, and a call between them is started (step S67).

  On the other hand, if the subscriber database 13 is not registered with the subscriber record having the received destination telephone number as the extension telephone number, the IP-PBX server 11 indicates that the destination telephone number is the telephone number of the outside line. Determination is made (step S68). Then, by sending the destination telephone number, the outgoing telephone number (external telephone number of the IP-PBX server 11) and the outgoing telephone number to another telephone network via the gateway 6, the outgoing telephone number is converted to the outgoing telephone number. Is made (step S69). Further, the IP-PBX server 11 generates a transmission history record for recording a transmission history to the destination outside telephone number, and additionally registers it in the transmission history database 18 (step S70). The call control unit of the other telephone network that has accepted the call from the IP-PBX server 11 makes a call to the call destination telephone terminal (external line) (step S71), and a response is returned from the call destination telephone terminal. Then (step S72), both the extension telephone terminal of the caller and the callee telephone terminal are connected, and a call between them is started (step S73). In addition, the destination telephone terminal (external line) returns a response in step S72, and is an external line telephone number notified from the call control unit (external line telephone number of the IP-PBX server 11) and a model capable of that. Record the extension telephone number notified at the same time.

  FIG. 7 is a configuration example of a call history database that records a history of external line calls from extension telephone terminals. As shown in FIG. 7, the outgoing call history record registered in each row of the outgoing call history database 18 is composed of fields of a call destination outside line telephone number, an outgoing line telephone number, a call date and time, and a response completion flag. Here, the destination external telephone number is a telephone number of a destination transmitted from an arbitrary extension telephone terminal to a telephone number other than the extension terminal (external line). The extension telephone number is the telephone number of the extension telephone terminal that has made a call to the outside line. In the transmission date and time, the date and time when the transmission to the outside line is performed and the transmission history record is added is registered. The response completion flag is a flag indicating whether or not a response to an incoming call from the outside telephone number of the call history record has been made. If no response has been made yet, “0” is already set. If there is an incoming call and a response is made, “1” is registered. As will be described later with reference to FIG. 12, this response flag is used to select a destination when an incoming call is received from an external line telephone terminal.

  FIG. 8 is a configuration example of the special number database held in the storage unit of the IP-PBX server 11 (see FIG. 2). As shown in FIG. 8, the special number record registered in each line of the special number database 19 is composed of fields of special number, incoming call ranking, terminal phone number, and remarks. Here, the special number is a special telephone number defined by a three-digit number such as “119” or “110”, and it is possible to define a plurality of terminal telephone numbers for receiving calls addressed to the special number. It is. In the incoming call ranking, the incoming call priority orders are registered in order from “1” when a plurality of terminal telephone numbers for receiving the same special number are defined. In the terminal telephone number, a unique telephone number of the extension telephone terminal that receives each special number is registered. Any additional information is described in the remarks. The data input to the special number record of the special number database 19 is performed by an administrator such as a local government using the management terminal 12 (see FIG. 2).

  FIG. 9 is a sequence diagram of an operation for calling a special number from an extension telephone terminal registered as a subscriber. First, a call request is sent from the extension telephone terminal to the IP-PBX server 11 (step S91), and a response to the call request acceptance is returned from the IP-PBX server 11 (step S92). Next, a special number (for example, “119”) is sent from the extension telephone terminal as the destination telephone number (step S93). When the IP-PBX server 11 determines that the received destination telephone number is a special number, the IP-PBX server 11 searches the special number database 19 using the special number as a key to obtain the terminal telephone number of the destination. At this time, when a plurality of special number records are registered for the same special number, the terminal telephone numbers and the incoming ranks registered in all the special number records are acquired. Then, the IP-PBX server 11 selects the highest terminal ranking from the acquired terminal telephone numbers, and searches the subscriber database 13 for a subscriber record having the terminal telephone number as an extension telephone number. Thus, the MAC address and IP address for calling the destination telephone terminal via the LAN are acquired (step S94). If the selected telephone terminal is busy, the terminal telephone number with the next highest incoming order is selected. Subsequently, the IP-PBX server 11 makes a call to the destination telephone terminal for the special number selected using the acquired MAC address and IP address (step S95), and a response is returned from the destination telephone terminal. When this is done (step S96), both the extension telephone terminal of the caller and the destination telephone terminal are connected, and a call between them is started (step S97).

  FIG. 10 is a first sequence diagram for a return call operation from an external telephone terminal that has received a call from an internal telephone terminal. When receiving a call from the extension telephone terminal, the caller telephone terminal (external line) is notified of the external telephone number of the IP-PBX server 11 as the caller telephone number, and the number is recorded. Further, depending on the type of the outside line telephone terminal, the extension telephone number that is the caller is also received and recorded at the same time.

  Therefore, the user of the caller telephone terminal (external line) makes a return call to the notified external telephone number of the IP-PBX server 11 (step S101). As a result, when an incoming call is made to the IP-PBX server 11 via another telephone network (and the gateway 6 (see FIG. 1)), the IP-PBX server 11 responds to the incoming call and uses the talkie to connect to the extension telephone number of the connection destination. Is requested (step S102). If the caller telephone terminal (outside line) has also recorded the extension telephone number that was the caller when the call from the extension telephone terminal was received, the recorded extension telephone number by the user's operation is stored in the IP-PBX server. 11 is transmitted. If not, a mobile phone number or a fixed phone number of a relative or acquaintance who seems to be in the affected area is input and transmitted (step S103). Next, the IP-PBX server 11 searches the call history database 18 using the caller telephone number notified at the time of an incoming call as a key. As a result, if there is a call history addressed to the source telephone number, it is determined whether it is a call history from the connected extension telephone number received, and if there is a corresponding call history, it is determined that the call can be received. Then, the MAC address and IP address for calling the extension telephone terminal connected via the LAN are acquired (step S104). If there is no corresponding call history, the call is disconnected after announcing that the call cannot be made because no call is made from the connected extension telephone number received (not shown). If it is determined that the incoming call is possible, the IP-PBX server 11 performs a call to the corresponding extension telephone terminal (step S105), and when a response is returned from the connected extension telephone terminal (step S106), Both the caller telephone terminal (external line) and the connected extension telephone terminal are connected, and a call between them is started (step S107).

  FIG. 11 is a second sequence diagram for the return call operation from the external telephone terminal that has received the call from the internal telephone terminal. In the operation of the second sequence diagram, candidates for extension telephone numbers of destinations are guided on the basis of outgoing histories from the extension telephone terminals to the external telephone terminals, and the connection destinations can be selected from them. As a result, the convenience of the return call from the external telephone terminal can be improved, and it is possible to notify the user of the external telephone terminal that there is a call from a specific telephone terminal user.

  As in the case of the first sequence diagram, the user of the caller telephone terminal (external line) that has received the call from the extension telephone terminal returns to the notified external telephone number of the IP-PBX server 11. A call is made (step S111). As a result, when an incoming call is made to the IP-PBX server 11 via the other telephone network (and the gateway 6), the IP-PBX server 11 searches the outgoing call history database 18 using the notified source telephone number as a key. As a result, if there is a call history addressed to the caller telephone number, for example, "This is a temporary exchange for XX. Please select a connection destination. Extension number that called you last: 090-xxxx" When selecting -yyyy, enter "1". "Announcement" (step S112). If there are a plurality of corresponding outgoing histories, the extension numbers registered in the plurality of outgoing histories are sequentially guided, and an announcement is made so that a destination is selected. Next, the IP-PBX server 11 sends a selection number transmission request to the caller telephone terminal (step S113), and the selection number input by the user is transmitted to the IP-PBX server 11 (step S114). ). The IP-PBX server 11 specifies the extension telephone number of the connection destination from the received selection number, and acquires the MAC address and IP address for calling the corresponding extension telephone terminal via the LAN (step S115). Subsequently, the IP-PBX server 11 calls the corresponding extension telephone terminal using the acquired MAC address and IP address (step S116), and when a response is returned from the extension telephone terminal ( In step S117), both the caller telephone terminal (external line) and the callee extension telephone terminal are connected, and a call between them is started (step S118).

  FIG. 12 is a third sequence diagram for the return call operation from the external telephone terminal that has received the call from the internal telephone terminal. In the operation of the third sequence diagram, the extension telephone number of the destination is automatically selected based on the outgoing call history from the extension telephone terminal to the external telephone terminal, and the incoming call is received. As a result, it is possible to simplify the operation of the return call from the external telephone terminal, and the user of the external telephone terminal that has received the call from a plurality of extension telephone terminal users can select the other party who has not yet made the call by the return call. You can call it with priority.

  As in the case of the first and second sequence diagrams, the user of the caller telephone terminal (external line) that has received a call from the extension telephone terminal can call the notified external line telephone number of the IP-PBX server 11. Then, a return call is made (step S121). As a result, when an incoming call is made to the IP-PBX server 11 via the other telephone network (and the gateway 6), the IP-PBX server 11 searches the outgoing call history database 18 using the notified source telephone number as a key. As a result, if there is a call history addressed to the caller telephone number, a call-out extension telephone number recorded in the call history is selected as a call destination, and a MAC for calling the corresponding call extension telephone terminal via the LAN. An address and an IP address are acquired (step S122). If there are a plurality of corresponding outgoing histories, the extension telephone number that has not been answered (the response completion flag is “0”) and that has the latest outgoing date / time is selected as the destination from the plurality of outgoing histories. . Next, the IP-PBX server 11 makes a call to the extension telephone terminal corresponding to the selected extension telephone number (step S123), and when a response is returned from the extension telephone terminal (step S124). Then, both the caller telephone terminal (external line) and the called extension telephone terminal are connected, and a call between them is started (step S125). The IP-PBX server 11 changes it to “1” (response completed) if the response completion flag of the call history record from the corresponding extension telephone terminal that has responded is “0” (unresponse). (Step S126). Thereby, when a call is made from a plurality of extension telephone terminals to the telephone number of the same external line, the extension telephone terminals that have not yet made a return call can be preferentially received.

  Although the description of the embodiment of the present invention has been completed above, the embodiment of the present invention is not limited to this, and various modifications can be made without departing from the spirit of the present invention.

According to the present invention, the following effects can be further obtained.
(1) It is possible to suppress impersonation of a subscriber by reading out subscriber data of a cellular phone terminal used as an extension telephone terminal from the SIM card and registering as a subscriber.
(2) Although the subscriber registration function of the PBX server is released to the subscriber, the subscriber data registration can be speeded up. However, the release to the subscriber may alter the data of other subscribers. There is. On the other hand, in the present invention, for example, since the subscriber registration function is divided into the telephone terminal side and the PBX server side, only the authority to register subscriber data related to a specific telephone terminal is given to the subscriber. Therefore, it is possible to reduce the risk of falsification of other subscriber data.
(3) Since an extension telephone network can be constructed without wiring a dedicated telephone line by an IP network using a wireless LAN or a wired LAN, an extension telephone service can be quickly set up in a disaster area. In addition, since there is no need for equipment setting work or additional board addition work by a telephone contractor or the like, which is necessary in the conventional PBX system, the operation load is reduced.
(4) An extension network in a remote LAN can be centrally managed by a single IP-PBX server via an IP network.
