Abstract: Facsimile apparatus stores, in a memory, a telephone number for connecting to a server of an Internet facsimile transmission service company. The facsimile apparatus transmits facsimile signals via the Internet, a registration number of a user of the service company, a facsimile number of the destination, and a protocol for connecting to the service company. Connection to a server of the service company is established by pressing a button and further processing for connection with the Internet is executed. The server of the service company converts the image information of the facsimile signals as received from the facsimile apparatus into image data of its own format appropriate for Internet transfer, selects a second server which is located close to the destination based on the destination facsimile number, and transfers the data via the Internet. The second server reconverts the image data into a format conforming to the destination facsimile, connects to the destination facsimile, and transmits the data.
