Parameter Description
Answer Detector Sensitivity
[AnswerDetectorSensitivity]
Determines the Answer Detector sensitivity.
The range is 0 (most sensitive) to 2 (least sensitive). The default is 0.
CAS Transport Type
[CASTransportType]
Controls the ABCD signaling transport type over IP.
 [0] CAS Events Only = Disable CAS relay (default).
 [1] CAS RFC2833 Relay = Enable CAS relay mode using RFC
2833.
The CAS relay mode can be used with the TDM tunneling feature to
enable tunneling over IP for both voice and CAS signaling bearers.
DTMF Generation Twist
[DTMFGenerationTwist]
Defines the range (in decibels) between the high and low frequency
components in the DTMF signal. Positive decibel values cause the
higher frequency component to be stronger than the lower one.
Negative values cause the opposite effect. For any parameter value,
both components change so that their average is constant.
The valid range is -10 to 10 dB. The default value is 0 dB.
