Understanding The Phone Startup Process - Cisco 7962G Administration Manual

Understanding the Phone Startup Process

If you configure security-related settings in Cisco Unified Communications Manager Administration,
the phone configuration file will contain sensitive information. To ensure the privacy of a configuration
file, you must configure it for encryption. For detailed information, refer to the "Configuring Encrypted
Phone Configuration Files" chapter 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 from the TFTP server when
the following conditions exist:
•
•
•
If auto registration is not enabled and the phone has not been added to the
Cisco Unified Communications Manager Database, the phone registration request will be rejected. In
this case, the phone will reset and attempt to register repeatedly.
If the phone has registered before, the phone will access 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:
•
•
•
The filenames are derived from the MAC Address and Description fields in the Phone Configuration
window of Cisco Unified Communications Manager Administration and the devicename field in the
Cisco Unified Communications Manager database. The MAC address uniquely identifies the phone. For
more information refer to the Cisco Unified Communications Manager Administration Guide.
