Upon failure to successfully transmit at least one of the first fax pages of the fax document to the one or more recipient fax machines, the router for converting the failed fax pages to secondary email packets for re-transmission thereof to the one or more recipient fax machines, wherein the router behaves as a conventional fax machine by re-transmitting only failed fax pages thereby avoiding re-transmission of the entire fax document.
