Malformed DTMF Detection Method
Defines the value for the Positive Twist DTMF detection
parameter.
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 parameter. 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.
