  At this time, the input number may be set as an extension telephone number of another extension telephone. At this time, if the telephone exchange system does not allow the setting of one extension telephone number to a plurality of extension telephones, the entered number can be set as the extension telephone number of the extension telephone. Can not.

  In this case, the user manually searches for an unset number that is not set as an extension telephone number for other extension telephones, for example, by checking a table that lists the set extension telephone numbers, and finds it by that search. The unset number must be entered again into the extension telephone. For this reason, there is a problem that it takes much time to set the extension telephone number.

  Such a problem occurs, for example, when an extension telephone is further added to a telephone exchange system that is already in operation. In particular, if this telephone exchange system is a large-scale system having many extension telephones or a system in which extension telephone numbers are set in a complicated manner, the entered number is set to another extension telephone. The number of searches for extension telephone numbers increases. As a result, it takes a lot of time to set the extension telephone number.

  Patent Document 1 describes an automatic extension number assignment system that can reduce the time and effort required to set an extension telephone number in an IP telephone.

  This automatic extension number assignment system includes N IP telephones and a SIP server. The SIP server stores N extension telephone numbers from 1 to N that can be set in the IP telephone. Each IP phone transmits a unique ID to the SIP server. The SIP server sets the extension telephone number from the first to the IP telephone with the unique ID in the order in which the unique ID is received.

As a result, when an extension telephone number is set for an IP telephone, the user does not need to manually search for an unset number, so that it is possible to reduce time and effort for setting the extension telephone number.

  A setting number / key pressing condition processing unit (hereinafter referred to as a setting processing unit) 28 is an example of a mode setting unit. The setting processing unit 28 sets one of the normal mode and the extension number setting mode for each port number.

  When the port 22a of the port number for which the normal mode is set receives the operation number, the setting processing unit 28 determines whether or not the operation number is a special number. If the operation number is a special number, the setting processing unit 28 sets the extension number setting mode as the operation mode of the port number of the port 22a that has received the operation number. Here, the special number is a predetermined special number, for example, a three-digit number starting with 9. Further, a range of numbers that can be set as extension telephone numbers (hereinafter referred to as a settable range) is determined in advance, and the special number is a number outside the settable range.

  In addition, when the port 22a having the port number for which the normal mode is set receives the operation signal, the setting processing unit 28 passes the operation signal and the port number that has received the operation signal to the function execution unit 33.

When the port 22a receives the operation number, the search unit 30 searches the database 25 for the operation number. Further, every time the port 22a receives an operation signal, the search unit 30 changes the operation number to a number closest to the operation number. The search unit 30 searches the database 25 for the changed operation number every time the operation number is changed. The setting screen display control unit 31 displays the search result on the display unit 12 of the telephone 1 connected to the port 22a that has received the operation signal.

  In this case, each time a predetermined key is operated, the operation number is changed to a number closest to the operation number. Each time the operation number is changed, the changed operation number is searched from the database 25.

  Accordingly, since the extension telephone numbers not stored in the database 25 are unset numbers that are not set in the extension telephones, each time a predetermined key is operated, the extension telephone numbers are assigned to the other telephones 1 in order from the number closest to the operation number. It becomes possible to search for an unset number that is not set as a telephone number. Therefore, when the desired extension telephone number is already set in another extension telephone, it becomes possible to find an unset number close to the desired extension telephone number.

  In this embodiment, the management means transmits the first operation signal as the operation signal when the first predetermined key is operated, and the second operation as the operation signal when the second predetermined key is operated. Send a signal. Each time the port 22a receives the first operation signal, the search unit 30 changes the operation number to a number closest to the operation number among numbers larger than the operation number. Further, every time the port 22a receives the second operation signal, the search unit 30 changes the operation number to a number closest to the operation number among numbers smaller than the operation number.

  In this case, every time the first predetermined key is operated, it becomes possible to search for an unset number in ascending order from a number close to the operation number, and every time the second predetermined key is operated, It becomes possible to search for an unset number in descending order from a number close to the number. Therefore, it is possible to reflect the user's wishes.

  In the present embodiment, the predetermined key is also used as a function key for executing a predetermined function. In this case, since it is not necessary to provide a predetermined key only for searching for an unset number, it is possible to suppress an increase in the size of the telephone 1.

  In the present embodiment, the predetermined key is also used as a volume adjustment button for adjusting the volume of the received voice. In this case, since the volume control button is usually provided in the telephone 1, it is not necessary to change the appearance of the telephone 1. For this reason, it is possible to suppress an increase in the cost of the telephone 1.

  In the present embodiment, the first predetermined key is also used as the volume increase button 14a for increasing the volume of the received voice, and the second predetermined key is also used as the volume decrease button 14b for decreasing the volume of the received voice. The

  In this case, the volume increase button 14a and the volume decrease button 14b are normally provided in the telephone 1, so that it is not necessary to change the appearance of the telephone 1. For this reason, it is possible to suppress an increase in the cost of the telephone 1.

  If the search unit 30 cannot find the search number, the registration unit 32 sets the operation number as the extension telephone number of the telephone 1 connected to the port 22a that has received the operation number.

  In this case, it is possible not only to automatically search for the unset number, but also to automatically set the unset number as the extension telephone number in the telephone 1.

  Next, a second embodiment will be described.

  When the connection unit 42 receives the search number, the search unit 30 searches the database 25 for the search number.

  In addition, each time the connection unit 42 receives an operation signal, the search unit 30 changes the operation number received by the connection unit 42 to a number closest to the operation number. Each time the search unit 30 changes the operation number, the search unit 30 searches the database 25 for the changed operation number.

  The setting screen display control unit 31 displays the search result of the search unit 30 on the display unit 12 of the telephone 1 connected to the connection unit 42 that has received the operation number.

  Next, the operation will be described.

  First, the user operates the dial key 13 of the telephone 1 and inputs a number desired to be set as an extension telephone number to the telephone 1.

  The management unit 17 of the telephone 1 transmits an operation number corresponding to an operation on the dial key 13 in the operation unit 15 to the main device 2. When the connection unit 42 of the main apparatus 2 receives the operation number, it transmits the operation number and the identification information of the own connection unit 42 to the search unit 30.

  When receiving the operation number and the identification information, the search unit 30 searches the database 25 for the operation number and generates a search result. The search unit 30 transmits the search result and identification information to the setting screen display control unit 31.

  When the setting screen display control unit 31 receives the search result and the identification information, the setting screen display control unit 31 displays the search result on the display unit 12 of the telephone 1 connected to the connection unit 42 of the identification information.
