Chapter 2 Preparing to Install the Cisco Unified IP Phones on Your Network
Understanding Phone Configuration Files
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 detailed information, refer to
Configuring Encrypted Phone
Configuration Files in Cisco Unified Communications Manager Security Guide. 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 containing a certificate assigned to the Cisco Unified Communications
Manager and TFTP.
If auto registration is not enabled and you did not add the phone to the Cisco Unified Communications
Manager database, the phone does not attempt to register with Cisco Unified Communications Manager.
The phone continually displays the Configuring IP message until you either enable auto-registration or
add the phone to the Cisco Unified Communications Manager database.
If the phone has registered before, the phone accesses the configuration file named
SEPmac_address.cnf.xml, where mac_address is the MAC address of the phone.
The TFTP server generates these SIP configuration files:
• SIP IP Phone:
–
For unsigned and unencrypted files—SEP<mac>.cnf.xml
–
For signed files—SEP<mac>.cnf.xml.sgn
–
For signed and encrypted files—SEP<mac>.cnf.xml.enc.sgn
• Dial Plan—<dialplan>.xml
• Softkey Template—<softkey_template>.xml
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. For more information, see Cisco Unified Communications Manager Administration
Guide.
