That is, the call processing control unit 30 determines whether or not the incoming call number matches any of the dial-in numbers of the extension telephones 4a to 4d indicated by the dial-in number information stored in the system data unit 32.

  When it is determined that the incoming number matches any of the dial-in numbers of the extension telephones 4a to 4d, the call processing control unit 30 performs dial-in control (individual incoming call control) from the external telephone 2 to the extension telephone 4 for outgoing calls. (S3). That is, the call processing control unit 30 causes a call from the external telephone 2 to be received by the extension telephone 4 having the dial-in number designated by the call. As a result, the extension telephone 4 with the dial-in number calls for an incoming call.

  Further, at that time, the call processing control unit 30 receives the extension number indicating the extension telephone 4 of the incoming call number based on the incoming call number and the caller number (the telephone number of the caller's external telephone 2) indicated in the outgoing call. The incoming call information in which the telephone information and the caller information indicating the caller with the caller number are associated is generated and stored in the storage unit 11 (S4).

  Here, as shown in FIG. 6, when the caller information indicates the caller name, the caller name that may make a call to the dial-in numbers of the extension telephones 4a to 4d, Information associated with the caller number may be stored in the storage unit 31 in advance. Then, the call processing control unit 30 specifies the caller name from the caller number indicated by the call from the external telephone 2 based on the information, and generates the caller information to indicate the caller name. What should I do? Further, as described above, when the caller number is non-notified, the caller information is generated so as to indicate non-notification. As shown in FIG. 6, when the incoming extension telephone information indicates an extension number and a user name, information associated with the incoming call number, the extension number, and the user name is stored in advance in the same manner. 31, and the call processing control unit 30 specifies the extension number or the user name from the incoming call number based on the information, and indicates the extension number and the user name to indicate the extension number and the user name. The telephone information may be generated.

  Here, when there is an incoming call to another extension telephone 4 during an incoming call to the extension telephone 4, the processes of the above-described steps S <b> 1 to S <b> 4 are also executed for the extension telephone 4. Hereinafter, a case will be described in which each of the three extension telephones 4a to 4c in which no user is present is receiving a call from each of the three external telephones and responds to any one of the calls from the extension telephone 4d. That is, the call processing control unit 30 continues the description from the state in which the incoming call information for each of the three extension telephones 4 a to 4 c is stored in the storage unit 31.

  When the user of the extension telephone 4d wants to know the incoming call status of the extension telephone group to which the extension telephones 4a to 4d belong, the extension telephone group to which the extension telephone 4d belongs ("extension telephone group") is sent to the operation unit 41 of the extension telephone 4d. Dial the incoming call information acquisition number (shown as “A”) and perform the outgoing call operation. The operation unit 41 generates input information indicating the input content in response to an input for dialing an incoming information acquisition number from the user, and outputs the input information to the control unit 40. The control unit 40 transmits the incoming information acquisition number indicated by the input information to the private branch exchange 3 in response to the output of the input information indicating the input for dialing the incoming information acquisition number from the operation unit 41 (S5). That is, the control unit 40 transmits to the private branch exchange 3 information requesting incoming call list information, which is a list of incoming call information of the extension telephone group to which the extension telephone 4d belongs, as a call origination information acquisition number.

  The call processing control unit 30 of the private branch exchange 3 responds to the incoming call of the dial number transmitted from the extension telephone 4d, based on the operation dial information stored in the system data unit 32, what kind of processing the operation dial performs. Analyze whether the operation dial is instructing the execution of. When the call processing control unit 30 determines that the operation dial is an incoming information acquisition number dial for instructing transmission of incoming call information of the extension telephone group of the extension telephone 4d, the extension telephone stored in the system data part 32 Based on the group information, among the incoming information stored in the storage unit 31, the incoming information on the extension telephone 4 belonging to the extension telephone group of the extension telephone 4d is acquired (S6). The call processing control unit 30 transmits the acquired incoming call information to the extension telephone 4d as incoming call list information (S7). Here, the incoming information of each of the extension telephones 4a to 4c is transmitted as incoming list information.

  The control unit 40 of the extension telephone 4d displays a list of incoming calls indicated by each incoming call information on the display unit 42 in response to reception of incoming call information transmitted from the private branch exchange 3. Thereby, for example, as shown in FIG. 6, the incoming call list 420 is displayed on the display unit 42 of the extension telephone 4d.

  When the user of the extension telephone 4d wants to respond to an incoming call to any of the extension telephones 4 on behalf of the user of the extension telephones 4a to 4c that are receiving calls, the user of the extension telephone 4d responds to the operation unit 41 of the extension telephone 4d. Then, a dial for selecting an incoming call of the extension telephone 4 that responds from the incoming call list 420 is entered. For example, when the incoming call list 420 shown in FIG. 6 is displayed on the display unit 42, when the user selects the incoming call “Sato (1111): First Trading”, the user presses the dial button “1” on the operation unit 41. When the incoming call “Suzuki (2222): Second product” is selected, the dial button “2” of the operation unit 41 is pressed, and when the incoming call “Yamada (3333): Not notified” is selected, the operation unit 41 is selected. The dial button “3” is pressed.

  The operation unit 41 generates input information indicating the input contents according to an input for selecting an incoming call (extension telephone 4) from the user by dialing, and outputs the input information to the control unit 40. The control unit 40 transmits the dial number to the private branch exchange 3 according to the output of the input information indicating the input for selecting the incoming call from the operation unit 41 by dial (S8). That is, the control unit 40 transmits information notifying the selected incoming call to the private branch exchange 3 as a dial number.

  The call processing control unit 30 of the private branch exchange 3 specifies the selected incoming call based on the dial number in response to the incoming call of the dial number transmitted from the extension telephone 4d (S9). For example, when the incoming information is transmitted in step S7, information indicating what display order (corresponding order with the dial number) each incoming call is stored in the storage unit 31 as the incoming call list. The incoming call corresponding to the dialed number may be specified based on the information.

  The call processing control unit 30 transmits response method list information indicating a list of possible response methods for the specified incoming call to the extension telephone 4d (S10). That is, the contents of the list of response methods provided may be changed depending on which extension telephone 4 is received. For example, each of the extension telephones 4a to 4d sets any two or more response methods as a response method list in different combinations among the response methods such as the proxy response, the guidance response, and the answering machine response described above. You may do it. For example, the response method list information corresponding to each of the extension telephones 4a to 4d is stored in the storage unit 31 in advance, so that the response method list information corresponding to the identified extension telephone 4 is stored in the storage unit. 31 to obtain and transmit.

  In response to receiving the response method list information transmitted from the private branch exchange 3, the control unit 40 of the extension telephone 4d displays the response method list indicated by the response method list information on the display unit 42. Thereby, for example, as shown in FIG. 6, a response method list 421 is displayed on the display unit 42 of the extension telephone 4d.

  The user of the extension telephone 4d inputs a dial for selecting a response method from the response method list to the operation unit 41 of the extension telephone 4d. When the response method list 421 shown in FIG. 6 is displayed on the display unit 42, for example, when selecting the response method “proxy response”, the user presses the dial button “1” of the operation unit 41 to respond. When the method “guidance response” is selected, the dial button “2” of the operation unit 41 is pressed, and when the response method “answering answer” is selected, the dial button “3” of the operation unit 41 is pressed.

  The operation unit 41 generates input information indicating the input content according to an input for selecting a response method from the user with a dial, and outputs the input information to the control unit 40. The control unit 40 transmits the dial number to the private branch exchange 3 in response to the output of the input information indicating the input for selecting the response method from the operation unit 41 by dial (S11). That is, the control unit 40 transmits information for notifying the selected response method to the private branch exchange 3 as a dial number transmission.

  The control unit 30 of the private branch exchange 3 identifies the selected response method based on the dial number in response to the incoming dial number transmitted from the extension telephone 4d (S12). For example, when the response method list information is transmitted in step S10, information indicating the display order (corresponding order with the dial number) of each response method as the response method list is stored in the storage unit 31. And a response method corresponding to the dialed number may be specified based on the information. The control unit 30 responds to the incoming call selected by the extension telephone 4d by the specified response method (S13).

  Specifically, when “proxy response” is selected as the response method, the control unit 30 determines that the incoming call identified in step S9 as selected by the extension telephone 4d and the extension external telephone 2 and the extension A connection is established with the telephone 4d, and voice information in a call is transferred between the telephones 2 and 4. As a result, it is possible to make a call with the external telephone 2 by the extension telephone 4d on behalf of the extension telephone 4 that is the destination of the external telephone 2.

  When “guidance response” is selected as the response method, the control unit 30 establishes a connection with the caller's external telephone 2 for the incoming call specified in step S9 as selected by the extension telephone 4d. Then, voice information indicating the voice of the guidance prompting the user to make another call is transmitted to the external telephone 2. As a result, the external telephone 2 can output a guidance voice prompting the user to make another call to the user of the external telephone 2 based on the voice information.

  If “answering machine answering” is selected as the response method, the control unit 30 establishes a connection with the external telephone 2 that is the source of the incoming call specified in step S9 as selected by the extension telephone 4d. Then, the voice information indicating the voice of the guidance prompting the recording of the message is transmitted to the external telephone 2 and the voice related to the voice information transmitted from the external telephone 2 is recorded. As a result, the external telephone 2 can output a guidance voice prompting the recording of a message to the user of the external telephone 2 based on the voice information. In addition, the control unit 30 records a message from the user of the external telephone 2 in accordance with it. For example, the control unit 30 records the message from the user by storing the voice information indicating the voice from the user of the external telephone 2 in the storage unit 31.

  Note that the message stored in the private branch exchange 3 is, for example, the voice information stored in the storage unit 31 by the call processing control unit 30 in accordance with the transmission of the operation dial instructing the reproduction of the recorded message from the extension telephone 4. By transmitting to the telephone 4, the extension telephone 4 can reproduce the recorded message based on the voice information.
