Multi-QoS Alarms
For Multi-QoS alarms, alarms can be created from the Multi-QoS Views interface
as well as by double-clicking on the host.
The
Codecs field within the alarm editor allows you select a specific codec or to
ignore the type of codec used. For example, to trigger the alarm only when a G.711
codec is used, set the
Codecs field to G.711. To trigger the alarm without looking at
the codec type, set the
Codecs field to All Codecs.
Multi-QoS uses a simple threshold value to trigger the alarm. When the threshold
value is crossed, the alarm is triggered and the alarm action is taken. Most alarms
trigger when the current value exceeds a threshold, such as for call jitter. However,
the R-factor alarms trigger when the current value goes below the threshold value.
The lower the R-factor, the lower the call quality, so alarms trigger when the R-
factor drops below a threshold.
The alarm conditions are checked for each call; if threshold values are reached,
alarms will trigger only once per call.
