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 CM. In general, any time you make a change in Cisco Unified CM that requires the phone
to be reset, a change is automatically made to the phone's configuration file.
Configuration files also contain information about which image load the phone should be running. If this
image load differs from the one currently loaded on a phone, the phone contacts the TFTP server to
request the required load files.
A phone accesses a default configuration file named XmlDefault.cnf.xml from the TFTP server when
the following conditions exist:
•
•
•
In addition, if the device security mode in the configuration file is set to Authenticated and the CTL file
on the phone has a valid certificate for Cisco Unified CM, the phone establishes a TLS connection to
Cisco Unified CM. Otherwise, the phone establishes a TCP connection.
