Unsigned32
When the high-group frequency of a DTMF is more powerful
than the low-group frequency, the difference between the
high-group frequency absolute power and the low-group
frequency absolute power must be smaller than or equal to the
value set in this variable. Otherwise, the DTMF is not
detected.
Raising this value increases the sensitivity of DTMF detection.
Raising this value too high may also cause false detections of DTMFs.
This variable's semantics are different depending on protocol and/or
hardware platforms. Please refer to the documentation
for more details.
