phone_setting.vq_rtcpxr_moslq_threshold_warning
15 to 40
Blank
Description:
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 collector.
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.
Web User Interface:
Settings->Voice Monitoring->Warning threshold for Moslq
Phone User Interface:
None
phone_setting.vq_rtcpxr_moslq_threshold_critical
15 to 40
Blank
Description:
Configures the desired 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 the central report collector. When the MOS-LQ
value computed by the phone is greater than 2.8, the phone will not send a critical
alert quality report to the central report collector.
If it is set to blank, critical alerts are not generated due to MOS-LQ.
Web User Interface:
Settings->Voice Monitoring->Critical threshold for Moslq
