Abstract: A simple VoIP terminal and a communication method thereof which allow facsimile communication by a VoIP terminal unequipped with H.323D facilities. Whether or not a call request from a facsimile/telephone terminal is followed by a CNG signal is determined. If the CNG signal is detected, G.711 CODEC alone is selected from among a plurality of audio CODECs provided in advance to create a CODEC list. A call request is issued to a calling party with the CODEC list included.
