Abstract
In a network facsimile communication system including Internet fax devices and a server, the Internet fax devices have both a capability of exchanging fax images over a public switched telephone network PSTN and a capability of exchanging messages over the Internet. The server has a file transfer capability and is provided on the Internet. A called Internet fax device sends, upon incoming of a call from the PSTN, an Internet fax indication to a calling Internet fax device, the indication indicating that the called device has an Internet fax capability. The calling Internet fax device sends, after the Internet fax indication is received, an universal resource locator URL, indicating a location of the server on the Internet as a destination of a fax image, to the called Internet fax device, releases the call from the PSTN, and transmits the fax image to the server corresponding to the URL. The called Internet fax device accesses the server on the Internet by using the received URL, so that the called Internet fax device receives the fax image from the server.
