  • Publication number: 20090316182
    Abstract: A method and system for managing facsimile (fax) data in an integrated manner. The system includes an integrated fax server, and a fax terminal configured to transmit and receive fax data via a first communication network and to transmit both the transmitted and received fax data to the integrated fax server via a second communication network. The integrated fax server stores fax data received from the fax terminal in a database. The fax terminal includes a fax machine connector configured to receive fax data from a fax machine, a first communication network connector configured to transmit and receive fax data via a first communication network, and a server interface unit configured to transmit fax data to the integrated fax server. Accordingly, the integrated fax server manages transmitted and received fax documents with increased efficiency and security. Thus, the difficulty of managing fax documents due to spacial restriction is diminished.
