Voice Quality Reports Configuration
The following table lists the parameters you can use to configure the service quality reports.
Parameter
phone_setting.vq_rtcpxr.session_report.enable <y0000000000xx>.cfg
Description
It enables or disables the phone to send a session quality report to the central report collector at the
end of each call.
Permitted
Values
0-Disabled
1-Enabled
Default
0
Web UI
Settings > Voice Monitoring > VQ RTCP-XR Session Report
Parameter
phone_setting.vq_rtcpxr.interval_report.enable <y0000000000xx>.cfg
Description
It enables or disables the phone to send an interval quality report to the central report collector peri-
odically throughout a call.
Permitted
Values
0-Disabled
1-Enabled
Default
0
Web UI
Settings > Voice Monitoring > VQ RTCP-XR Interval Report
Parameter
phone_setting.vq_rtcpxr_interval_period <y0000000000xx>.cfg
Description
It configures the interval (in seconds) for the phone to send an interval quality report to the central
report collector periodically throughout a call.
Note: It works only if “phone_setting.vq_rtcpxr.interval_report.enable” is set to 1 (Enabled).
Permitted
Values
Integer from 5 to 20
Default
20
Web UI
Settings > Voice Monitoring > Period for Interval Report
Parameter
phone_setting.vq_rtcpxr_moslq_threshold_warn-
ing
<y0000000000xx>.cfg
Description
It configures the threshold value of listening MOS score (MOS-LQ) multiplied by 10. The threshold
value of MOS-LQ causes the phone to send a warning alert quality report to the central report col-
lector.
For example, a configured value of 35 corresponds to the MOS score 3.5. When the MOS-LQ value
computed by the phone is less than or equal to 3.5, the phone will send a warning alert quality report
to the central report collector. When the MOS-LQ value computed by the phone is greater than 3.5, the
phone will not send a warning alert quality report to the central report collector.
If it is set to blank, warning alerts are not generated due to MOS-LQ.
Permitted
Values
Integer from 15 to 40
Default
Blank
Web UI
Settings > Voice Monitoring > Warning Threshold for Moslq
Parameter
phone_setting.vq_rtcpxr_moslq_threshold_critical <y0000000000xx>.cfg
Description
It configures the threshold value of listening MOS score (MOS-LQ) multiplied by 10. The threshold
value of MOS-LQ causes the phone to send a critical alert quality report to the central report collector.
For example, a configured value of 28 corresponds to the MOS score 2.8. When the MOS-LQ value
computed by the phone is less than or equal to 2.8, the phone will send a critical alert quality report to
