5.6.2.6 Media Settings ini File Parameters
Table 5-47 describes the Media Settings parameters that can only be configured via the ini
file.
Table 5-47: Media Settings, ini File Parameters (continues on pages 162 to 163)
ini File Parameter Name Valid Range and Description
RTPSIDCoeffNum
Determines the number of spectral coefficients added to an SID packet
being sent according to RFC 3389. Valid only if
‘EnableStandardSIDPayloadType’ is set to 1.
The valid values are 0 (default), 4, 6, 8 and 10.
ECHybridLoss
Sets the four wire to two wire worst case Hybrid loss, the ratio between the
signal level sent to the hybrid and the echo level returning from the hybrid.
[0] = 6 dB (default)
[1] = 9 dB
[2] = 0 dB
[3] = 3 dB
FaxModemRelayVolume
-18 to -3, corresponding to -18 dBm to -3 dBm in 1 dB steps. (Default = -12
dBm) fax gain control.
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).
DTMFDigitLength
Time in msec for generating DTMF tones to the PSTN side (if
TxDTMFOption = 1, 2 or 3).
The default value is 100 msec. The valid range is 0 to 32767.
DTMFInterDigitInterval
Time in msec between generated DTMF digits to PSTN side (if
TxDTMFOption = 1, 2 or 3).
The default value is 100 msec. The valid range is 0 to 32767.
TestMode [0] = CoderLoopback, encoder-decoder loopback inside DSP.
[1] = PCMLoopback, loopback the incoming PCM to the outgoing PCM.
[2] = ToneInjection, generates a 1000 Hz tone to outgoing PCM.
3 = NoLoopback, (default).
ModemBypassPayloadType
Modem Bypass dynamic payload type.
The valid range is 0 to 127. The default value is 103.
BellModemTransportType
Determines the Bell modem transport method.
[0] = Transparent (default).
[2] = Bypass.
[3] = Transparent with events.
FaxModemBypassBasicRtpPa
cketInterval
Determines the basic frame size that is used during fax / modem bypass
sessions.
[0] = set internally (default)
[1] = 5 msec
[2] = 10 msec
[3] = 20 msec
Note: When set for 5 msec (1), the maximum number of simultaneous
channels supported is 120.
FaxModemBypassDJBufMinDe
lay
Determines the Jitter Buffer delay during fax and modem bypass session.
The valid range is 0 to 150 msec. The default is 40.
EchoCancellerAggressiveNLP
Enables or disables the Aggressive NLP in the first 0.5 second of the call.
[0] = Disabled (default)
[1] = Enabled
