  In step S504, the management server 101 refers to the external line information table and determines whether or not the system number that matches the received “80001234” exists in the external line information table. If it is determined that there is a matching system number, the process proceeds to step S505 to execute an outside line transmission using the system number. If it is determined that the system number is not correct, the system number is incorrect, and the process is terminated without executing the outside line transmission by the system number.

  In step S505, the management server 101 searches the external line information table (702 in FIG. 7) for a system number that matches the received destination number “80001234”, and identifies the external line uniquely associated with the matched system number. Search for telephone numbers on the telephone network.

  Further, as the destination number conversion process, the received destination number “80001234” is converted into the telephone number “080-2222-2222” of the telephone network of the searched outside line.

  Further, as a source number conversion process, an extension number matching the received source number “4700001” is searched from the extension information table (703 in FIG. 7), and the dial-in uniquely associated with the matched extension number is searched. The number “050-1111-1111” is searched, and the received transmission source number “4700001” is converted into the searched dial-in number “050-1111-1111”.

  In step S506, the management server 101 uses the converted dial-in number “050-1111-1111” as a transmission source number, and receives an incoming call request including the transmission source number converted into the dial-in number from the incoming telephone network. Send to receive first.

Further, as an incoming call request processing for the incoming call destination number, an incoming call including the incoming call destination number converted to the telephone number of the external telephone network is set with the converted telephone number “080-2222-2222” of the external telephone network as the incoming call destination number. Send the request to the destination on the outside telephone network.
The incoming call request processing for the incoming call destination number makes it possible to receive an incoming call on the external telephone network (external line telephone).

  The destination (customer) of the external telephone network that can receive calls from the extension type mobile phone 401 by an external telephone is a mobile terminal outside the company that does not have a contract to use the FMC service network provided by the mobile terminal carrier. A user or a landline user. The telephone number “080-2222-2222” of the external telephone network used when receiving an incoming call to the destination (customer) of the external telephone network is a telephone number that should be taken care of for managing information as personal information.

  In step S507, the outside line telephone receives an incoming call request including the transmission source number converted into the dial-in number and the destination number converted into the telephone number of the outside line telephone network from the management server 101 and receives the incoming call. When the incoming request from the management server 101 is received, the management server 101 and the external telephone establish communication through the GW server. This establishment of communication means that the establishment of communication via the management server 101 is completed between the extension type mobile phone 401 and the outside line telephone.

  Reference numeral 601 in FIG. 6 denotes an external telephone to an extension telephone (extension type mobile telephone) 401 described using the conversion processing executed by the management server 101 described in FIG. 4 and the telephone number (information) actually used in the present invention. This is a description of the steps of the telephone number processing when a call is made.

  In 601 of FIG. 6, the user X (customer) whose telephone number of the external telephone network is “080-2222-2222” is the extension type mobile phone of the user Y (employee) who uses the FMC service from the external telephone. In order to receive a call 401, an extension type is made by requesting an incoming call with "050-1111-1111" (dial-in number), which is the telephone number of the destination of the extension telephone network assigned to user Y (employee). Description will be made assuming that the incoming call to the mobile phone 401 is completed.

  Reference numeral 601 in FIG. 6 indicates that the user X (customer) having “080-2222-2222” (telephone number of the outside line telephone network) is a number known by the user X (customer) “050-1111-”. This is a telephone number process when a user Y (employee) having a telephone number “1111” (dial-in number) wants to make a call (request for incoming call).

The user X who makes an incoming call request with the telephone number of the external telephone network “080-2222-2222” described here is a general user (customer). The general user here means that it is not an internal user such as an employee, which will be described later. Furthermore, the person who does not use the FMC service.
In step S601, the user X (customer) makes a call (incoming call request) from the external phone of the user X to the extension type mobile phone 401 of the user Y (employee).
In that case, an incoming call request is made using “080-2222-2222” (the telephone number of the telephone network of the outside line) as the caller number.

In step S602, the management server 101 receives the source number “080-22222-2222” and the destination number “050-1111-1111” via the GW server by routing that is a known technique. (Process of S403)
Further, the transmission source number “080-2222-2222” and the destination number “050-1111-1111” are registered in the call history table 701.
In step S <b> 603, the management server 101 refers to “080-2222-2222”, which is a transmission source number, from the outside line information table. (Processing of S404)

  In step S604, the management server 101 searches the external line information table for the telephone number of the external telephone network that matches the received transmission source number “080-2222-2222”. A system number that is uniquely associated with the telephone number of the searched external telephone network is further searched. (Processing of S404)

  If there is no telephone number of the external telephone network that matches the received transmission source number “080-2222-2222” in the external line information table, a new system number is issued. (Processing of S405)

  For example, the newly issued system number is a unique system number “80001242” that does not overlap with the number registered so far in the external line information table, and is newly registered in association with the received transmission source number.

  Thus, if the source number is the telephone number of the external telephone network that is received for the first time (not registered in the external line information table), an individual system number that does not overlap with the system number already registered in the external line information table Can be newly registered by uniquely associating it with the received transmission source number.

  In step S605, the management server 101 converts the received transmission source number “080-2222-2222” into the system number “80001234” retrieved from the external line information table. (Processing of S406)

  Further, the management server 101 uses the extension information table to display the received destination number “050-1111-1111” and the destination telephone number of the extension telephone network that matches the received destination number “050-1111-1111”. The retrieved number is converted into an extension number “4700001” uniquely associated with the destination telephone number of the retrieved extension telephone network. (Processing of S406)

  In step S606, the management server 101 issues an incoming call request to the extension type mobile phone 401 of the user Y (employee) with the converted transmission source number “80001234” and the converted destination number “4700001”. (Processing of S407)

  Reference numeral 602 in FIG. 6 indicates that the extension telephone (extension mobile phone) 401 described using the conversion process executed by the management server 101 described in FIG. 5 and the telephone number (information) actually used in the present invention is changed to an external telephone.

"050-1111-1111" (dial-in number), which is the destination telephone number of the extension telephone network assigned to user Y (employee) in order to receive the extension type mobile phone 401 of person Y (employee) Suppose that user Y (employee) makes a return call (incoming call request) to user X after receiving an incoming call from the external telephone to the extension type mobile phone 401 by making an outgoing call (incoming call request). I will explain.

  Reference numeral 602 in FIG. 6 indicates that a user Y (employee) having a telephone number of “050-1111-1111” (dial-in number), which is a number known to the customer, is “080-22222-2222” (external line telephone). This is telephone number processing when it is desired to make an incoming call request to a user X having a network telephone number).

  In step S611, the user Y (employee) extension type mobile phone 401 having the number “050-1111-1111” makes an incoming call request to the external phone of the user X (customer). In this case, an incoming call request is made using “80001234” (system number) instead of “080-2222-2222” (telephone number of the outside telephone network).

  “80001234” is an external telephone network telephone stored in the management server 101, which is assigned so as to uniquely correspond to the external telephone telephone number of the user X (customer) known only to the user Y (employee). It is a number that can be converted to a number.

  At the same time as making an incoming call request with “80001234” (system number) as the destination number, “4700001” (extension number) is sent to the management server 101 as the source number.

In step S612, the management server 101 receives the transmission source number “4700001” and the destination number “80001234” via the A company GW server 102 by routing which is a known technique. (Process of S503)
In step S613, the management server 101 refers to “80001234” that is the destination number from the outside line information table. (Processing of S504)

  In step S614, the management server 101 searches the external line information table for a system number that matches the received destination “80001234”. The telephone number of the outside telephone network uniquely associated with the retrieved system number is further searched. (Processing of S505)

  In step S615, the management server 101 converts the received destination number “80001234” into the telephone number “080-2222-2222” of the external telephone network retrieved from the external line information table. (Processing of S505)

  Further, the management server 101 searches the extension information table for the received source number “4700001” for the extension number that matches the received source number “4700001”, and the extension telephone uniquely associated with the searched extension number The telephone number of the network destination is converted to “050-1111-1111”. (Processing of S505)

In step S616, the management server 101 makes an incoming call request to the external telephone of the user X (customer) with the converted transmission source number “050-1111-1111” and the converted destination number “080-2222-2222”. To do. (Processing of S506)

  In step S813, it is determined whether a telephone number of an external telephone network that has not been subjected to telephone number update processing remains in the telephone directory. If it is determined that the telephone number remains, the process proceeds to step S804. If it is determined that there is no remaining, the process proceeds to step S814.

  In step S814, the update server 105 transmits the telephone book including the system number generated in step S812 to the extension telephone (first telephone book transmission means). The update server 105 transmits the phone book including the extension number generated in step S812 to the extension phone (second phone book sending means).

In step S815, when the telephone directory including the system number is transmitted from the update server 105, the extension telephone receives the telephone directory including the system number. The extension telephone receives the telephone book including the extension number when the telephone book including the extension number is transmitted from the update server 105.
Note that the telephone directory received in step S815 may be a telephone directory that includes both system numbers and extension numbers.

  In step S816, the extension telephone exchanges (replaces) the telephone directory as shown in 706 of FIG. 10 transmitted in step S802 and the telephone directory phonebook as shown in 707 of FIG. 10 received in step S815. The telephone directory (personal telephone directory data) stored in the extension telephone is updated.

  In step S <b> 821, the management server 101 duplicates the latest external line information data (702 in FIG. 7) stored therein, and transmits the duplicated external line information data to the update server 105.

  In step S822, the update server 105 receives the copied external line information data from the management server 101 before receiving the telephone directory including the telephone number of the external telephone network stored in the internal telephone in step S803. (Outside line information data receiving means).

  In step S823, the update server 105 updates the external line information data stored therein to the external line information data copied by the management server 101 received in step S822 (first external line information data updating unit).

In step S824, the update server 105, after registering the system number in step S810, duplicates the latest external line information data (705 in FIG. 7) stored therein and transmits the duplicated external line information data to the management server 101.
