Viewing the quality of your call1
XT Series endpoints display a graphical indicator representing the overall quality of each call link.2
The link quality indicator level is evaluated separately for audio, video, and presentation streams,3
based on the average packet loss percentage of the last five seconds. The worst of the three4
calculated levels is then displayed.5
Quality Average Packet Loss
Icon Level Audio Video Presentation
Excellent <=3 <=1 <=1
Good >3 >1 >1
Normal >7 >3 >3
Bad >10 >5 >5
Problematic >15 >10 >10
For example, if the overall link quality indicator level is Excellent, it means that the average packet6
loss is now less than 3% for audio, 1% for video, and 1% for presentation.7

• In a point to point call, the link quality indicator level is displayed in the XT Series user9
