Syntax

C#
public bool DtmfDecoderSetTwist(
	double ForwardTwistDb,
	double ReverseTwistDb
)
Visual Basic (Declaration)
Public Function DtmfDecoderSetTwist ( _
	ForwardTwistDb As Double, _
	ReverseTwistDb As Double _
) As Boolean
Visual C++
public:
bool DtmfDecoderSetTwist(
	double ForwardTwistDb, 
	double ReverseTwistDb
)
J#
public boolean DtmfDecoderSetTwist(
	double ForwardTwistDb,
	double ReverseTwistDb
)

Parameters

ForwardTwistDb
Type: System..::.Double
The allowable DTMF forward twist in dB. The 0dB reference is taken to be sine wave full scale 16 bit PCM. Values in the range of 0dB to any positive dB value can be specified.
ReverseTwistDb
Type: System..::.Double
The allowable DTMF reverse twist in dB. The 0dB reference is taken to be sine wave full scale 16 bit PCM. Values in the range of 0dB to any positive dB value can be specified.

Return Value

If the function succeeds, the return value will be non zero.

If the function fails, the return value will be zero.
