Network Quality Levels
Network quality is determined by the percentage of packet loss according to the following default threshold
values:
● Packet loss less than 1% is considered Normal
● Packet loss in the range of 1% - 5% is considered Major
● Packet loss above 5% is considered Critical.
The default Major and Critical indication threshold values can be manually modified by changing the system
flag values.
Major and Critical states are indicated with yellow and red indicator bars respectively.
When network quality improves from Critical to Major remaining stable for 5 seconds, the Network Quality
Indicator is changed accordingly and when network quality improves from Major to Normal, remaining stable
for 5 seconds, the Network Quality Indicator is no longer displayed.

conference) to be heard during an ongoing conference. If Roll Call is enabled for the conference, a roll call
can be requested. In addition, various other massages may be heard during the conference, if enabled. For
