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
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.

Parameter
phone_setting.vq_rtcpxr_delay_threshold_warn-
ing
<y0000000000xx>.cfg
Description
It 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. The one-way delay
includes both network delay and end system delay.

VQ-RTCPXR Display
You can check the voice quality data of the last call via the web user interface or phone user interface. You can also
specify the options of the RTP status to be displayed on the phone user interface. Options of the RTP status dis-
played on the web user interface cannot be specified.
