摘要： There is a need to provide a technique of accurately detecting an identification signal representing that the partner performs facsimile communication, by using an appropriate detection filter in accordance with the operation mode in a facsimile apparatus. Based on whether the FAX/TEL mode (first mode) or the TEL answering mode (second mode) is set as the operation mode, a facsimile apparatus according to this invention determines whether a band-pass filter and band-reject filter are to be used. The facsimile apparatus detects a CNG based on the signal detection result using the determined filter.

摘要： When a facsimile device detects an audio signal via a CNG signal detection unit while detecting an OFF signal in a CNG signal during a telephone conversation, the facsimile device does not detect the audio signal as an OFF signal if the level of the detected audio signal is greater than a threshold and the frequency of the audio signal is within a predetermined audio frequency range. Accordingly, the facsimile device can reliably prevent a false detection of a noise that has a similar signal component to a CNG signal as a CNG signal. It is possible to prevent the facsimile machine from being automatically shifted to a facsimile receiving mode by the false detection of the noise.

摘要： 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.
