Phone Configuration Files

The TFTP server stores the phone configuration files that define parameters for connecting to Cisco
Unified Communications Manager. In general, any time you make a change in Cisco Unified Communications
Manager that requires the phone to be reset, a change is automatically made to the configuration file for the
phone.
Configuration files also contain information about the image load that the phone should be running. If this
image load differs from the one that is 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:
• You enable autoregistration in Cisco Unified Communications Manager.
• You have not added the phone to the Cisco Unified Communications Manager database.
• The phone is registering for the first time.
If the device security mode in the configuration file is set to Authenticated or Encrypted, but the phone
Note
has not received a CTL or ITL file, the phone makes four attempts to obtain the file so the phone can
register securely.
If autoregistration is not enabled and the phone does not exist in the Cisco Unified Communications Manager
database, the system rejects the phone registration request and a blank screen displays.
If the phone has registered previously, the phone accesses the SEPmac_address.cnf.xml configuration file,
where mac_address is the MAC address of the phone.
The filenames are derived from the MAC address and description fields in the Phone Configuration window
of Cisco Unified Communications Manager Administration. The MAC address uniquely identifies the phone.
