FAX
FAX / Modem: Select the mode to detect if there is a fax tone and transfer the call to a fax line.
Note: When a fax tone is detected from the call, the VoIP Telephone Adapter will automatically switch
from voice mode to fax mode. Hence, the fax settings will be temporarily applied to a specific port which
detects the fax tones, instead of its default voice settings.
