SIP User's Manual 4. ini File Configuration
Parameter Description
UDTDetectorFrequencyDevi
ation
Defines the deviation (in Hz) allowed for the detection of each signal
frequency.
The valid range is 1 to 50. The default value is 50.
CPTDetectorFrequencyDevi
ation
Defines the deviation (in Hz) allowed for the detection of each CPT
signal frequency.
The valid range is 1 to 30. The default value is 10.
MGCPDTMFDetectionPoint
[0] = DTMF event is reported on the end of a detected DTMF
digit.
[1] = DTMF event is reported on the start of a detected DTMF
digit (default).
KeyBlindTransferAddPrefix
Determines whether the device adds the Blind Transfer code
(KeyBlindTransfer) to the dialed destination number.
[0] Disable (default).
[1] Enable.
Note: This parameter is applicable to FXO and FXS interfaces.
VoicePayloadFormat
Determines the bit ordering of the G.726/G.727 voice payload
format.
[0] = Little Endian (default)
[1] = Big Endian
Note: To ensure high voice quality when using G.726/G.727, both
communicating ends should use the same endianness format.
Therefore, when the device communicates with a third-party entity
that uses the G.726/G.727 voice coder and voice quality is poor,
change the settings of this parameter (between Big Endian and Little
Endian).
