jitter buffer. The default is 60.
nom level Specify the nominal size of the simulated jitter
buffer. The default is 30.
rtdelay ms Estimate of round trip delay if no RTCP records
are detected. The default is 60 milliseconds
(ms).
quality yes|no Enable alarms for low quality R-factor. The
default is yes.
burst yes|no Enable alarms for excessive bursting. The
default is yes.
delay yes|no Enable alarms for excessive bursting. The
default is yes.
rquality seconds Alarm trigger for low quality R-Factor. The
default is 60.

duration (in ms). The default is 500 ms.
delaymax ms Maximum alarm trigger for excessive delay (in
ms). The default is 450 ms.
qalertclear seconds Minimum duration until the low quality alarm
is cleared. The default is 3 seconds.

alarm is cleared. The default is 3 seconds.
dalertclear seconds Minimum duration until the excessive delay
alarm is cleared. The default is 3 seconds.
