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.
