Abstract
The communication cost for image information transmission from a facsimile machine connected to the international PSTN to an overseas destination is significantly reduced by causing a first repeater Internet facsimile machine installed in the same country as the transmitting machine to perform a repeater operation for transferring the image information to a second repeater Internet facsimile machine installed in the same country as the recipient machine. The cost is reduced because no additional communication charge is incurred for the image information transfer between the repeater Internet facsimile machines.
