Parameter Reference
INI File Parameter Name = cpFilterHighCutoff
Note: Unit requires a restart if this parameter value is changed.
3.10.2.14 Call Progress Filter SNR in dB (DMG2000 Only)
Description: Specifies the Signal to Noise Ratio (SNR) of the Call Progress Tone Detector. Call
progress signals whose SNR is lower than specified will be ignored.
Allowed Values: 0 dB to 40 dB
Default Value = 20 dB
INI File Parameter Name = cpFilterSnr
Note: Unit requires a restart if this parameter value is changed.
3.10.2.15 Call Progress Filter Two Tones Max Twist in dB (DMG2000 Only)
Description: Specifies the maximum twist for two tone Call Progress Tones. Call progress signals
that consist of two tones whose power ratio of the tones is greater than the specified twist will be
ignored.
Allowed Values: 0 dB to 12 dB
Default Value = 3 dB
INI File Parameter Name = cpFilterMaxTwist
Note: Unit requires a restart if this parameter value is changed.
3.10.2.16 Jitter-Buffer Minimum Delay (DMG2000 Only)
Description: Specifies the minimum jitter-buffer delay. The smaller the delay, the smaller the
jitter-buffer. It is recommended that this value be at least the duration of one RTP packet interval. If
the minimum, maximum, and initial jitter-buffer delays are set to the same value, the jitter-buffer
will operate in the non-adaptive mode.
Allowed Values: 0 to 200 milliseconds
Default Value = 20 milliseconds
INI File Parameter Name = dspJbDelayMinMs
3.10.2.17 Jitter-Buffer Maximum Delay (DMG2000 Only)
Description: Specifies the maximum jitter-buffer delay. A larger delay provides protection against
larger network jitter, but increases audio delay. It is recommended that this value be set to at least
four times the duration of one RTP packet interval. If the minimum, maximum, and initial jitter-
buffer delays are set to the same value, the jitter-buffer will operate in the non-adaptive mode.
