Power Outage
Your accessibility to emergency service through the phone is dependent on the
phone being powered. If there is an interruption in the power supply, Service and
Emergency Calling Service dialing will not function until power is restored. In the
case of a power failure or disruption, you may need to reset or reconfigure
equipment before using the Service or Emergency Calling Service dialing.
Understanding Phone Configuration Files
Configuration files for a phone are stored on the TFTP server and define
parameters for connecting to Cisco
Unified CallManager. In general, any time
you make a change in Cisco
Unified CallManager that requires the phone to be
reset, a change is made to the phone configuration file automatically.
