	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

		case, the phone must be manually added to
		the Cisco Unified Communications
		Manager database.
