A facsimile apparatus capable of facsimile communication in a high-speed mode and a low-speed mode comprises a circuit (100, 22) for transmitting calling information to a communication line (2) of a digital communication network first in the high-speed mode. The facsimile apparatus further comprises a circuit (22) for making facsimile communication in the high speed mode when a response signal to the call made in the high-speed mode has been sent back, a circuit (100, 21) for making a call in the low-speed mode when the response signal has not been sent back, and a circuit (21) for making facsimile communication in the low-speed mode when a response signal to the call made in the low speed mode has been sent back. This facsimile apparatus further comprises a memory (9) storing destination specifying information and communication mode specifying information corresponding to the destination specifying information, a circuit (100) making access to the memory to retrieve communication mode specifying information corresponding to entered destination specifying information when a transmission starts, a circuit (100, 21, 22) making a call according to the corresponding communication mode specifying information when it exists, and a circuit (100, 22) making a call in the high-speed mode when the corresponding communication mode specifying information does not exist. This structure enables facsimile communication to be made always corresponding to the communication capability of a destination apparatus even when communication modes provided to the destination apparatus are not known.
