Abstract

A method for facsimile transmission over a packet network includes establishing a facsimile call between first and second facsimile terminals in accordance with a facsimile protocol, using a facsimile gateway to convey communications between the terminals over the packet network. The gateway awaits the arrival of a signal conveyed over the packet network from the first terminal, to be transmitted from the gateway to the second terminal as provided by the protocol, and it transmits a fill page to the second terminal if the signal does not arrive within a time limit determined in accordance with the protocol. Upon receiving the signal, the gateway transmits the signal to the second terminal after transmitting the fill page.
