voice.vadThresh
1
integer from 0 to 30
15
The threshold for determining what is active voice and what is background noise in dB. Sounds louder than this
value will be considered active voice, and sounds quieter than this threshold will be considered background
noise. This does not apply to G.729AB codec operation which has its own built-in VAD function.

Voice Quality Monitoring Parameters
Parameter
Permitted Values
Default
voice.qualityMonitoring.collector.alert.moslq.threshold.critical
1
0 to 40
0
The threshold value of listening MOS score (MOS-LQ) that causes phone to send a critical alert quality report.
Configure the desired MOS value multiplied by 10. If 0 or Null, critical alerts are not generated due to MOS-LQ.
For example, a configured value of 28 corresponds to the MOS score 2.8.
voice.qualityMonitoring.collector.alert.moslq.threshold.warning
1
0 to 40
0
Threshold value of listening MOS score (MOS-LQ) that causes phone to send a warning alert quality report.
Configure the desired MOS value multiplied by 10. If 0 or Null, warning alerts are not generated due to MOS-LQ.
For example, a configured value of 35 corresponds to the MOS score 3.5.
voice.qualityMonitoring.collector.alert.delay.threshold.critical
1
0 to 2000
0
Threshold value of one way delay (in ms) that causes phone to send a critical alert quality report. If 0 or Null,
critical alerts are not generated due to one-way delay. One-way delay includes both network delay and end
system delay.
voice.qualityMonitoring.collector.alert.delay.threshold.warning
1
0 to 2000
0
Threshold value of one way delay (in ms) that causes phone to send a critical alert quality report. If 0 or Null,
warning alerts are not generated due to one-way delay. One-way delay includes both network delay and end
system delay.
voice.qualityMonitoring.collector.enable.periodic
1
0 or 1
0
If 0, periodic quality reports are not generated. If 1, periodic quality reports are generated throughout a call.
voice.qualityMonitoring.collector.enable.session
1
0 or1
0
If 0, quality reports are not generated at the end of each call. If 1, reports are generated at the end of each call.
