A phone accesses a default configuration file named XmlDefault.cnf.xml from the
TFTP server when the following conditions exist:
You have enabled auto-registration in Cisco Unified CallManager.
The phone has not been added to the Cisco Unified CallManager Database.
The phone is registering for the first time.
If security is implemented, a phone does not access the XmlDefault.cnf.xml
configuration file.
At all other times, a phone accesses a .cnf.xml file that corresponds to its device
name.
When it is connecting to the VoIP network, the Cisco Unified IP Phone goes
through a standard startup process that comprises seven steps, as described in
Table
2-3. Depending on your specific network configuration, some of these steps
may not occur on your Cisco Unified IP Video Phone.
