Abstract
In a system where fax messages are directed to a store and forward system when a fax machine is busy: When fax messages are stored and an attempt is made to re-deliver the message, an ID related to the serial number of the storage system is placed in the fax header. When a message is received by the store and forward system, the header is interrogated and if an ID related to the serial number of the receiving machine is detected, the fax is not again stored and the system notes that the transmission to the fax machine was not successful.
