Patent ID: 8896875

Claim:
A system for use in real-time facsimile transmissions between a transmission device and a reception device over a packet switched communication network, the system implementing a client-server model and including a restriction element, the system comprising: a transfer client communicably connectable to the transmission device on a client side of the client-server model; and a transfer server communicably connectable to the reception device on a server side of the client-server model; wherein the restriction element is communicably connectable between the transfer client and the transfer server, thereby separating the transfer client and the transmission device on the client side of the client-server model from the transfer server and the reception device on the server side of the client-server model, and wherein the transfer client operative: to receive a transmission from the transmission device; to pre-establish a communication session between the transfer client and the transfer server over non-pre-selected ports; and following pre-establishment of the communication session between the transfer client and the transfer server: to exchange transmission control messages with the transfer server via the pre-established communication session; and to send, via the pre-established communication session through the restriction element over the non-pre-selected ports, the transmission to the transfer server as a real-time transmission for receipt at the reception device.
