detection setting 0–10 4 = 440 Hz All continuous, busy and
ringing tones are

detected if one of their
components is between
400 and 500 Hz. If both
components are in this
range, set a lower
detection value. Set 0 for
400 Hz and 10 for 500 Hz.

affect the single tone
detection, which always
works between 300 and
550 Hz.
