		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 CallManager 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 CallManager identifies the phone.
		If the phone was not manually added to the
		database and auto-registration is enabled in
		Cisco Unified CallManager, the phone attempts to
		auto-register itself in the

		Note Auto-registration is disabled when

		Cisco Unified CallManager database.
