Then, the management server 200 sends the fax data to the multifunction apparatus 300 to the corresponding address according to the TCP / IP protocol and / or transmits the fax data to the predetermined address transmitted from the multifunction apparatus 100 and / or the fax data to the predetermined address. The data is stored in the database 800 (ST6, ST7 of FIG. 6, and STEP8 of FIG. 7). That is, the decryption / encryption unit 210 of the management server 200 decodes the fax data sending request signal to the predetermined address transmitted from the multifunction apparatus 100 and outputs the decoded fax data to the management server control unit 220. Then, the management server controller 220 sends a control signal for sending or storing the fax data to a predetermined address according to the fax data sending request signal to the predetermined address output from the decryption / encryption unit 210. Output to the unit 250. Subsequently, the management server interface unit 250 outputs fax data to a predetermined address to the encryption / decryption unit 260 according to a control signal output from the management server control unit 220 or stores the data in the database 800. Then, the encryption / decryption unit 260 transmits the fax data addressed to the predetermined address output from the management server interface unit 250 to the multifunction apparatus 300 at the corresponding address according to the TCP / IP protocol.

Subsequently, the multifunction apparatus 300 outputs the fax data through the fax 400 according to the PSTN when the predetermined address sent from the management server 200 is its own address, and if the address is not its own address, another multifunction apparatus of the corresponding address. And 500 in accordance with the TCP / IP protocol (S6 in Fig. 5, STEP9 to STEP12 in Fig. 7).

Then, the multifunction peripheral 500 outputs the fax data through the fax 400 according to the PSTN when the predetermined address transmitted from the management server 200 is its own address.

In addition, the management server 200 is a multifunction device (for example, a multifunction device (for example, 300) from the other multifunction device (for example, 300) to the multifunction device 100 or the corresponding address to the address requested to be sent according to the TCP / IP protocol , 1100, and then the multifunction peripheral 100 outputs the fax data through the fax 1000 according to the PSTN when the predetermined address sent from the management server 200 is its own address. If not, relaying according to the TCP / IP protocol to another multifunction apparatus 1100 of the corresponding address is a reverse process of the above-described process, and thus description thereof will be omitted.
