Behavior During Times of Network Congestion
Anything that degrades network performance can affect voice and video quality, and in some cases, can cause
a call to drop. Sources of network degradation can include, but are not limited to, the following activities:
•
Administrative tasks, such as an internal port scan or security scan
•
Attacks that occur on your network, such as a Denial of Service attack
To reduce or eliminate any adverse effects, schedule administrative network tasks during a time when the
devices are not being used or exclude the devices from testing.
