Abstract
A facsimile (fax) machine is arranged to automatically answer a call and to transmit a fax message if a document or stored message is awaiting transmission, otherwise the fax machine goes into a fax receive mode. In another arrangement, the fax machine is connected to a station port of a customer switching system such that an existing call at a system station set can be transferred to the fax machine when a fax message is to be transmitted or received as part of that call. In one embodiment a station set and fax machine are packaged together in one housing.
