Power outages and other devices can affect your Cisco Unified IP Phone.

Your access to emergency service through the phone depends on the phone being powered. If there is a power

interruption, Service and Emergency Calling Service dialing will not function until power is restored. In case

of a power failure or disruption, you may need to reset or reconfigure the equipment before using the Service

or Emergency Calling Service dialing.

Anything that degrades network performance can affect Cisco IP Phone 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 to the phones, schedule administrative network tasks during a time

when the phones are not being used or exclude the phones from testing.
