ABSTRACT:
Methods and apparatus for transmitting documents using the Internet are disclosed. In accordance with a preferred embodiment of the invention, a document (3200) which is to be transmitted to a recipient is fed into a local facsimile machine (3100). The document (3200) includes a cover sheet (3210) containing a destination facsimile number (5100) and number of sheets which contain the message to be transmitted to the destination. The sender then dials the local telephone number of a remote computer system (2000). The document (3200) is then transmitted to the remote computer (2000) via a modem (2400) over a local telephone line (7000). The remote computer (2000) then scans the cover sheet (3210) and extracts the destination facsimile number (5100). The document (3200) is then formatted for transmission via public switched data network, specifically Internet backbone network(s) (6000), and is routed from the remote computer system (2000) to a host network computer system (4000). The document is then routed via the Internet (6000) to a remote computer system (4100) near the destination facsimile, and ultimately is delivered to its destination (5100).
