To provide a facsimile machine and the like which is available for call and utilizing a data communication network, such as the Internets without troubles.
The facsimile machine IAF 10 is for real-time G3 facsimile communication as stipulated by the ITU Recommendations T, 38, using data communication net connecting means or data packet signal transmitting-receiving means. It comprises a means for detecting off-hook of a connected telephone for talking after connection of the telephone or means for detecting a dial number originating from the connected telephone. Based on the dial number signal detected, the facsimile machine generates a call-setting signal packet including a voice capacity and transmits it from data communication network connecting means. If the facsimile machine detects a voice capacity included in a received call connection signal packet from the data communication network connecting means, it connects a voice channel in the data communication network connecting means, to start a voice session.
