  • Patent number: 8422062
    Abstract: An apparatus and method that configures a facsimile transmission protocol for a facsimile device is disclosed. The method can include transmitting an echo request via a network connection to a facsimile device. The method can include receiving a response to the echo request via the network connection from the facsimile device. The method can include determining network throughput impairments based on the received response to the echo request. The method can include adjusting a facsimile transmission protocol based on the determined network throughput impairments. The method can include transmitting a facsimile message based on the adjusted facsimile transmission protocol.

  • Publication number: 20110296511
    Abstract: A system and a method of processing faxes are disclosed. The method includes receiving page(s) to be transmitted by a first fax device coupled to a fax transmission network. An address of a recipient is encoded in a field of a fax transmission. The fax transmission, including the page(s) and the encoded recipient address, is transmitted to a second fax device. The received page(s) of the fax are stored at the second fax device and a passcode is generated. The fax is not released for printing until the passcode is submitted to the second fax device.

  • Publication number: 20110296498
    Abstract: A system and a method of authenticating faxes are disclosed. The method includes receiving image data that includes at least one page to be transmitted by a sending fax device. An authentication code is generated at the sending fax device. The authentication code is transmitted to a receiving fax device. The receiving fax device determines whether the authentication code is one which is accepted. If it is, the receiving fax device authorizes commencement of the fax transmission.

  • Publication number: 20110292456
    Abstract: A system and a method of processing faxes are disclosed. The method includes receiving image data that includes a plurality of pages to be transmitted by a first fax device coupled to a fax transmission network. Page number information is encoded in a field of a fax transmission. The fax transmission, including the image data and encoded page number information, is transmitted to a second fax device coupled to the fax transmission network. Whether all pages of the fax transmission are received is determined, based on the transmitted page number information. When fewer than all pages of the fax transmission are received, the received pages of the image data are withheld at the second fax device. When all pages have been received, the pages are concatenated for printing without interruption.

  • Publication number: 20090086277
    Abstract: A method for sending an image data file over a network is herein described. In the method, the first device stores an image data file including a plurality of pages. The first device may receive the image data file from an access device via a network. The first device determines if the image data file has at least one tag. The at least one tag identifies a location for including at least one substitute or additional page within the plurality of pages of the image data file. The substitute or additional page(s) is scanned to generate image data comprising the substitute or additional page(s). The image data is then included at the location in the image data file identified by the tag. The image data file, with the substitute or additional page(s), is then sent from the first device to a second device via a network.

  • Publication number: 20090083366
    Abstract: A method and apparatus transmits an item that is in electronic form over multiple networks. The method begins by receiving the item that is to be electronically transmitted. The method separates the item into at least a first fragment and a second fragment, transmits the first fragment over a first network to a receiving device, and transmits the second fragment over a second network to the receiving device. After the receiving device receives all the different fragments, it combines the first fragment and the second fragment to reproduce the item.
