Further, the facsimile apparatus 1 requests the SIP server for a list of IP telephone numbers managed by the SIP server, and adds a list of IP telephone numbers previously held in the RAM 4 to the contents of the received IP telephone number list. It has a function to update.

  Processing operations executed when IP phone number registration processing or the like is performed in the facsimile apparatus 1 having the above-described configuration and functions will be described with reference to the flowchart shown in FIG. Note that the processing operation of the facsimile apparatus 1 described based on the following flowchart is executed in accordance with a command issued by the CPU 2 as a control unit based on a control program stored in the ROM 3.

  When a predetermined operation for registering an IP phone number is performed in the operation unit 12 of the facsimile apparatus 1, a list of IP phone numbers stored in the RAM 3 is displayed, for example, by displaying on the display unit 11 (S1). . When the user of the facsimile apparatus 1 refers to the output IP telephone number list and the operation unit 12 is operated and any IP telephone number is selected and designated, the facsimile apparatus 1 accepts this (S2: YES). Then, the SIP server is requested to register the selected IP telephone number in its own device 1 (S3). The request is made, for example, by transmitting information indicating that fact to the SIP server.

  The SIP server that has received the IP phone number registration request refers to the IP phone number management table managed by its own server to determine whether the IP phone number requested for registration has already been registered in another device. If the IP telephone number requested for registration is already registered in any of the apparatuses, the requested registration is rejected, and the fact is notified to the facsimile apparatus 1. On the other hand, if the IP telephone number requested for registration is not registered in any apparatus, the requested IP telephone number is registered in the facsimile apparatus 1 and a notification that the registration process is completed is sent to the facsimile. Perform on device 1.

  The facsimile apparatus 1 receives a response to the IP telephone number registration request from the SIP server, and if it is a notification that the registration of the requested IP telephone number is completed (S4: YES), the facsimile apparatus 1 is selected and designated. Information indicating that the registration of the IP telephone number is completed is displayed on the display unit 11, for example, to notify the user of the facsimile machine 1 (S5).

  On the other hand, the facsimile apparatus 1 receives a response to the IP telephone number registration request from the SIP server, and the response indicates that the registration is not permitted because the requested IP telephone number is registered in another apparatus. If it is (S4: NO), information indicating that registration of the requested IP telephone number has not been accepted is displayed on the display unit 11, for example, to notify the user of the facsimile apparatus 1. At the same time, information for requesting the user of the facsimile apparatus 1 to specify whether or not to request registration of another IP telephone number is displayed on the display unit 11 (S6). As the information requested to the user, for example, a message such as “Registration of the specified IP phone number was not permitted. Do you want to request registration of another IP phone number?” Is displayed on the display unit 11. To do.

  When there is an operation for designating that the user should request registration of another IP telephone number (S7: YES), the IP telephone selected in S2 from the list of IP telephone numbers stored in the RAM 3 A list of IP telephone numbers excluding the numbers is output, for example, by displaying it on the display unit 11 (S8). When the user of the facsimile apparatus 1 refers to the list of IP telephone numbers displayed and output, and the operation unit 12 is operated and any IP telephone number is selected and designated (S9: YES), the process goes to S3. Returning, the SIP server is requested to register the designated IP telephone number in its own apparatus 1, and the above-described series of processing operations are executed again. As described above, since it is impossible to select and specify an IP telephone number whose registration has already been rejected in S9, an IP telephone number whose registration has been rejected by mistake is selected twice, and unnecessary processing is repeated. Is prevented in advance.

  On the other hand, in S7, when there is an operation for designating that registration of other IP telephone numbers is not requested (S7: NO), the series of processing operations is terminated.

  Next, the processing operation when the facsimile apparatus 1 designates an IP telephone number and requests the SIP server for the location information of the apparatus in which the IP telephone number is registered will be described based on the flowchart shown in FIG.

  When a predetermined operation for starting processing for requesting position information of another facsimile apparatus is performed in the operation unit 12 of the facsimile apparatus 1, a list of IP telephone numbers stored in the RAM 3 is displayed on the display unit 11, for example. To output (S51). When the user of the facsimile apparatus 1 refers to the output IP telephone number list and the operation unit 12 is operated and any IP telephone number is selected and designated, the facsimile apparatus 1 accepts this (S52: YES). Then, the SIP server is requested for the location information of the device in which the selected IP telephone number is registered (S53). The request is made, for example, by transmitting information indicating that fact to the SIP server.

  The SIP server that has received the request for the location information reads the location information of the designated IP phone number from the correspondence table of the IP phone number and location information managed by the server, and sends it to the facsimile apparatus 1. Notice. Here, the location information may be information that can specify the location of the device on the network indirectly, such as an IP address, or may indirectly specify the location of the device on the network. For example, the facsimile apparatus 1 has a correspondence table of owner names and IP addresses, and if the owner name is transmitted from the SIP server to the facsimile apparatus 1 as information that can indirectly specify the position on the network, the received information is received. The facsimile machine 1 can acquire the IP address corresponding to the owner name as the position information based on the correspondence table.

  If the facsimile apparatus 1 does not receive a response to the position information requested in S53 from the SIP server (S54: NO), the error information is output by, for example, displaying it on the display unit 11 (S55). For example, a message such as “No response” is displayed on the display unit 11.

  When the facsimile apparatus 1 receives a response to the position information requested in S53 from the SIP server (S54: YES), the received position information is output by, for example, displaying it on the display unit 11, and the position information apparatus Information for requesting the user to specify whether or not to make an IP phone number change request is displayed on the display unit 11 (S56). For example, a message such as “Do you want to make a request to change the IP phone number for the device in which the IP phone number 050-111-222 is registered? Select yes, no.” Is displayed on the display unit 11. indicate.

  When the user of the facsimile apparatus 1 performs an operation for designating that the IP phone number change request is not made (S57: NO), the series of processing operations is terminated. On the other hand, when there is an operation for designating that an IP phone number change request is made (S57: YES), the IP phone number selected in S53 is removed from the list of IP phone numbers stored in the RAM 3 A list of IP telephone numbers is output, for example, by displaying it on the display unit 11 (S58).

  When one of the output IP telephone numbers is selected and designated as an alternative candidate by a predetermined operation of the user of the facsimile apparatus 1 (S59: YES), the IP telephone is sent to the apparatus of the positional information received in S54. A request for changing the number is made, and an alternative candidate for the IP telephone number selected and designated is transmitted (S60).

  When a response message is received from the other party who transmitted the IP telephone number change request in S60 (S61: YES), the received response message is output by displaying it on the display unit 11, for example (S62). On the other hand, when a response message has not been received from the counterpart device (S61: NO), error information is output, for example, by display on the display unit 11 (S63). For example, information such as “there is no response from the partner device. The partner device may not support this function” is displayed on the display unit 11.

  Next, an example of a procedure formed when one facsimile machine 1 requests the other facsimile machine 1 to change the IP telephone number will be described based on the sequence diagram of FIG. For convenience of explanation, the facsimile apparatus 1 that requests the change of the IP telephone number will be referred to as a facsimile apparatus 1A, and the facsimile apparatus 1 that is requested to change the IP telephone number will be referred to as a facsimile apparatus 1B.

  In the facsimile apparatus 1A, when a predetermined operation for deleting the registration of “050-111-1111”, which is an IP telephone number registered in the apparatus 1A, is performed, the facsimile apparatus 1A makes a request to the SIP server 21. Request for deletion of registration of the IP phone number “050-111-1111” is requested (T1), and the SIP server 21 registers the IP phone registered in the facsimile apparatus 1A from the management table of IP phone numbers managed by the SIP server 21 itself. The registration of the number “050-111-1111” is deleted, and information indicating that the registration deletion processing is completed is notified to the facsimile machine 1A (R1). If the IP telephone number is not yet registered, such as when the facsimile machine 1A is newly installed, it is of course unnecessary to delete the registration of the IP telephone number.

  Next, in the facsimile apparatus 1A, the above-described processing operations S1 to S3 are executed, and registration of “050-111-2222”, which is the IP telephone number registered in the facsimile apparatus 1B, is registered with the SIP server 21. (T2), since the IP telephone number is registered in the facsimile apparatus 1B, the SIP server 21 registers the IP telephone number by registering in the other apparatus 1B. Is sent to the facsimile apparatus 1A (R2). Upon receiving this response, the facsimile machine 1A notifies the display unit 11 of information indicating that registration of the IP telephone number is not permitted (S6).

  The user of the facsimile apparatus 1A looks at the information displayed on the display unit 11 and knows that the IP telephone number “050-111-2222” requested to be registered is already registered in another apparatus. Then, the user performs a predetermined operation for starting a process for requesting the SIP server for the location information of the apparatus in which the IP telephone number is registered, and the facsimile apparatus from the list of IP telephone numbers displayed on the display unit When the IP telephone number “050-111-2222” registered in 1B is selected, the facsimile apparatus 1A sends the location information of the facsimile apparatus 1B in which the selected IP telephone number is registered to the SIP server 21. Request (T3, S53) and receive the position information of the facsimile machine 1B from the SIP server 21 (R3). Subsequently, the user of the facsimile apparatus 1A performs an operation for designating that an IP telephone number change request should be made (S57: YES), and further, any IP address from the list of IP telephone numbers displayed in S58. When the telephone number is selected and designated as an alternative candidate (S59: YES), the facsimile apparatus 1A requests the facsimile apparatus 1B, which is the apparatus of the received position information, to change the IP telephone number “050-111-2222”. In addition, an IP phone number alternative candidate, for example, “050-111-1111” is transmitted (S60, T4).

  The facsimile apparatus 1B that has received the IP phone number change request and the alternative candidate outputs the fact that the change request has been received as a received message and outputs the alternative candidate IP phone number by display and designates whether or not to respond to the change request. Information for requesting the user to operate, for example, information as shown in FIG. When the user of the facsimile apparatus 1B performs an operation for designating either one, the facsimile apparatus 1B accepts it and transmits a response message of the designated result to the facsimile apparatus 1A (R101).

  The facsimile machine 1A outputs the response message received from the facsimile machine 1B by displaying it on the display unit 11 (S62), whereby the user of the facsimile machine 1A makes a request for changing the IP telephone number by the user of the facsimile machine 1B. It is possible to grasp the response. In the facsimile machine 1B, after the deletion process of the IP phone number “050-111-2222” and the registration process of the IP phone number “050-111-1111” which is the alternative candidate are performed (R102, R103), the facsimile machine 1B The apparatus 1A can request the SIP server 1A to register the IP telephone number “050-111-2222” that was originally registered in the facsimile apparatus 1B (T5), and can receive the registration of the IP telephone number. Note that R102 and R103 may be combined into one process for requesting a change of the IP telephone number.

  As is apparent from the above description, according to the facsimile apparatus according to the first embodiment of the present invention, the facsimile apparatus 1 is prompted to change the IP telephone number to another facsimile apparatus 1 by remote operation. Since the IP telephone number of the alternative candidate can be proposed, it is possible to smoothly change or exchange the IP telephone number between the facsimile apparatuses 1. Of course, the same advantage can be obtained between three or more facsimile machines 1.

  Next, a facsimile apparatus according to the second embodiment of the present invention will be described. The facsimile apparatus according to the second embodiment has the same hardware configuration and communication function as those of the facsimile apparatus 1 according to the first embodiment, but differs in that a processing operation described later is executed. Hereinafter, differences will be mainly described, and the same configurations and processing operations are denoted by the same reference numerals in the drawings, and description thereof will be omitted.

  As shown in the flowchart of FIG. 5, the facsimile apparatus according to the second embodiment, when it is determined in step S7 described in the first embodiment that registration of another IP telephone number is not requested. (S7: NO), a request is made to the SIP server for location information of another device in which the IP telephone number selected and designated in S2 is registered (S101). That is, according to the facsimile apparatus according to the second embodiment, the IP telephone number registration process and the IP telephone number change request process to another facsimile apparatus are continuously executed. When the processing operation is omitted and both the IP telephone number registration process and the IP telephone number change request process are performed, the operation by the user can be simplified.

  Next, a communication procedure exchanged between the two facsimile machines 1 and the SIP server 21 will be described based on the sequence diagram of FIG. Also in the second embodiment, the facsimile apparatus 1 that requests the change of the IP telephone number is referred to as a facsimile apparatus 1A, and the facsimile apparatus 1 that is requested to change the IP telephone number is referred to as a facsimile apparatus 1B. explain.

  First, the IP telephone number change request or the like is transmitted from the facsimile machine 1A to the facsimile machine 1B through the steps T1 to T4 described in the first embodiment (T4). However, the request for position information at T3 is executed by the processing operation of S101.

  When the facsimile apparatus 1B receives an IP phone number change request or the like, the fact that the change request has been received and the alternative candidate IP phone number are output, for example, by being displayed on the display unit 11, and the change request is also responded. The information for requesting the user to perform an operation for designating whether or not is output (S201). These outputs are, for example, information as shown in FIG. 6, that is, “Change to the following IP phone number is requested from another device.”, “050-111-1111”, “According to request Is displayed on the display unit 11.

  When the user of the facsimile machine 1B performs an operation (for example, selecting “Yes” displayed on the display unit 11 in FIG. 6) to specify that the IP phone number change request is to be accepted, and the facsimile machine 1B accepts the designation. (S202: YES), the facsimile apparatus 1B requests the SIP server 21 to delete the registration of the IP telephone number “050-111-2222” registered in the own apparatus 1B (S203). The SIP server 21 deletes the registration of the IP telephone number “050-111-2222” registered in the facsimile apparatus 1B from the IP telephone number table managed by the SIP server 21 itself, and registers it in the facsimile apparatus 1B. Information indicating that the deletion process has been completed is notified.

  Subsequently, the facsimile apparatus 1B requests the SIP server 21 to register the IP telephone number “050-111-1111” presented as an alternative candidate from the facsimile apparatus 1A (S204). Then, after receiving the registration completion notification from the SIP server 21, as a response to the change request, the facsimile apparatus 1A is notified that the change of the IP telephone number has been completed (S205). Note that the processes of S203 and S204 may be combined into one process for requesting a change of the IP telephone number.

  On the other hand, in S202, when an operation (for example, selecting “No” displayed on the display unit 11 in FIG. 6) for not responding to the request for changing the IP telephone number is performed (S202: NO), As a response to the change request, the facsimile apparatus 1A is notified that the IP telephone number is not changed (S206).

  As shown in the flowchart of FIG. 5, the facsimile apparatus 1A receives a response to the change request from the facsimile apparatus 1B (S61: YES), and the content is a notification that the change of the IP telephone number is completed ( (S102: YES), the process proceeds to S3, and the registration request process for the IP telephone number “050-111-2222” is performed again for the SIP server 21 (T5, S3), and the IP telephone number Get registered. On the other hand, if a response to the change request is received from the facsimile apparatus 1B (S61: YES) and the content is a notification that the IP phone number is not changed (S102: NO), the series of processing operations is terminated. .

  As is apparent from the above description, according to the facsimile apparatus according to the second embodiment of the present invention, when the facsimile apparatus 1B receives a change request, if an operation corresponding to the change request is performed by the user, The facsimile apparatus 1B automatically executes a processing operation for changing the IP telephone number of the own apparatus 1B to an alternative IP telephone number. Then, after completion of the change process, the facsimile apparatus 1A is notified of this, and the facsimile apparatus 1A that has received this notification automatically performs a processing operation for receiving registration of the IP telephone number that was originally registered in the facsimile apparatus 1B. Execute. As a result, the user's operation is further simplified as compared with the facsimile apparatus according to the first embodiment.

  In the first and second embodiments described above, the IP telephone number is described by taking one piece of account information as an example. Therefore, the IP telephone number in the embodiment of the present invention may be replaced with other account information.
