Therefore, according to the present embodiment, when the user manually inputs the setting information, if the set setting information can be used as it is without modification, the input of the set setting information can be omitted. Thus, it is possible to reduce the burden on the user in the setting work of the IP telephone 1 by manually inputting the setting information.

  The present invention is not limited to the above-described embodiments, and various modifications can be made within the scope of the gist.

  For example, in the above embodiment, the setting information management device 2 stores, for each IP telephone service, the IP telephone service provider in association with the global IP address assigned to the IP telephone service provider, For each provider, setting information necessary for using the IP telephone service is stored in association with the MAC address of the IP telephone service providing destination. Then, the provider associated with the global IP address included in the setting information request received from the IP telephone 1 is specified, and the specified provider is the IP telephone 1 having the MAC address included in the setting information. The setting information requested is specified. However, the present invention is not limited to this. The setting information management apparatus 2 associates the setting information necessary for using the IP telephone service with the MAC address of the IP telephone service providing destination for each range of the global IP address assigned by the provider to the IP telephone service providing destination. You may remember. The setting information management device 2 then assigns the global IP address included in the setting information request received from the IP telephone 1 to the IP telephone service provider, and sets the MAC address included in the setting information request. The setting information requested from the IP telephone 1 may be specified.

  In the above embodiment, the IP phone 1 transmits a setting information request including the global IP address of the NAT device 3 and the MAC address of the own IP phone 1 acquired from the STUN server 4 to the setting information management device 2. Yes. However, the present invention is not limited to this. Instead of including the global IP address of the NAT device 3 in the setting information request, the provider of the IP telephone service specified from the global IP address of the NAT device 3 may be included. In this case, in the setting information management apparatus 2, the provider included in the setting information request is the transmission source of the setting information request for using the IP telephone service based on the MAC address included in the setting information request. The setting information requested from the IP telephone 1 is specified.

  In the above embodiment, the MAC address of the IP telephone 1 may be omitted from the setting information request transmitted from the IP telephone 1 to the setting information management apparatus 2. In this case, the setting information management device 2 uses the global network of the NAT device 3 in place of the MAC address of the IP telephone 1 in the table 220 stored in the setting information storage unit 22 for each provider of the IP telephone service (see FIG. 9). The IP address is registered in the field 222. As a result, the same setting information is set in a plurality of IP telephones 1 under the same NAT device 3, so that the IP telephone 1 connects the SIP telephones to other IP telephones 1 under the same NAT device 3. The server 5 or the registrar server 6 is inquired about whether or not the registration process is performed, and the SIP server 5 or the registrar server 6 is registered only when no other IP telephones 1 under the same NAT device 3 perform the registration process. Perform the registration process.

  In the above embodiment, the functional configuration of the IP telephone 1 shown in FIG. 4 and the setting information management device 2 shown in FIG. 7 is an integrated logic such as ASIC (Application Specific Integrated Circuit) or FPGA (Field Programmable Gate Array).
