US Patent 7310160 Facsimile communication apparatus and method permitting reliable V.17 communication

This invention is to provide a facsimile communication apparatus and method in which when a receiver which supports V.34 communication receives a call, transmits an ANSam signal, and receives a CM signal indicating V.17 communication from the transmitter, V.17 communication can reliably be established. A facsimile communication apparatus for executing a protocol defined in ITU-T recommendation V.8 with respect to a partner apparatus and setting an image transmission mode executable with respect to the partner apparatus on the basis of the protocol includes an ANSam signal transmission unit, a CM signal reception units, and a control unit for, when a CM signal indicating V.17 communication is received after transmission of an ANSam signal, executing control so as not to respond to the CM signal.
