Phone Configuration Files

Phone configuration files are stored on the TFTP server and define Cisco Unified Communications Manager

connection parameters. In general, whenever you make a change in Cisco Unified Communications Manager

that requires the phone to reset, a change is made automatically to the phone configuration file.

Configuration files also contain information about the image load that the phone should be running. If this

image load differs from the one currently that is loaded on a phone currently, the phone contacts the TFTP

server to request the required load files. These load files are digitally signed to ensure the authenticity of the

file source.

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 Communications Manager, the phone establishes a TLS

connection to Cisco Unified Communications Manager. Otherwise, the phone establishes a TCP connection.

For SIP phones, a TLS connection requires that the transport protocol in the phone configuration file be set

to TLS, which corresponds to the transport type in the SIP Security Profile in Cisco Unified Communications

Manager Administration.

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 tries four times to obtain the file so it can register securely.

Cisco Extension Mobility Cross Cluster is an exception, in that the phone permits a TLS connection to

Note

Cisco Unified Communications Manager for secure signaling even without the CTL file.

If you configure security-related settings in Cisco Unified Communications Manager Administration, the

phone configuration file contains sensitive information. To ensure the privacy of a configuration file, you

must configure it for encryption. For more information, see the Cisco Unified Communications Manager

Security Guide, "Configuring Encrypted Phone Configuration Files" chapter.

A phone requests a configuration file whenever it resets and registers with Cisco Unified Communications

Manager.

A phone accesses a default configuration file named XmlDefault.cnf.xml only when the phone has not received

a valid Trust List file that contains a certificate assigned to Cisco Unified Communications Manager and

TFTP.

If autoregistration is not enabled and you did not add the phone to the Cisco Unified Communications Manager

database, the phone system rejects the phone registration request with Cisco Unified Communications Manager.
