phone_setting.vq_rtcpxr_moslq_threshold_critical
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 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.

phone_setting.vq_rtcpxr_delay_threshold_warning
Description:
Configures the threshold value of one way delay (in milliseconds) that causes the phone to
send a warning alert quality report to the central report collector.
For example, If it is set to 500, when the value of one way delay computed by the phone is
greater than or equal to 500, the phone will send a warning alert quality report to the
central report collector; when the value of one way delay computed by the phone is less
than 500, 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 one way delay. One-way delay
includes both network delay and end system delay.
