a critical 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 critical 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 critical alert quality report to the central report collector.
If it is set to blank, critical alerts are not generated due to one way delay. One-way delay
includes both network delay and end system delay.
