	certificates necessary for establishing a secure
	connection between the phone and Cisco Unified
	Communications Manager.

8.	Contacting Cisco Unified Communications Manager	• Resolving Startup Problems, page 9-1.
	The configuration file defines how the Cisco
	Unified IP Phone communicates with Cisco
	Unified Communications Manager and provides a
	phone with its load ID. After obtaining the file from
	the TFTP server, the phone attempts to make a
	connection to the highest priority Cisco
	Unified Communications Manager on the list. If
	security is implemented, the phone makes a TLS
	connection. Otherwise, it makes a non-secure TCP
	connection.
	If the phone was manually added to the database,
	Cisco Unified Communications Manager identifies
	the phone. If the phone was not manually added to the
	database and auto-registration is enabled in Cisco
	Unified Communications Manager, the phone
	attempts to auto-register itself in the Cisco
	Unified Communications Manager database.
	Note Auto-registration is disabled when security is
	enabled on Cisco Unified Communications
	Manager. In this case, the phone must be
	manually added to the Cisco Unified
	Communications Manager database.
