Request the CTL file. The TFTP server stores the CTL file. This file contains the certificates that are
necessary for establishing a secure connection between the phone and Cisco Unified Communications
Manager.

Request the ITL file. The phone requests the ITL file after it requests the CTL file. The ITL file contains
the certificates of the entities that the phone can trust. The certificates are used to authenticate a secure
connection with the servers or to authenticate a digital signature that is signed by the servers. Cisco Unified
Communications Manager 8.5 and later supports the ITL file.

Access a TFTP server. In addition to assigning an IP address, the DHCP server directs the phone to a
TFTP Server. If the phone has a statically defined IP address, you must configure the TFTP server locally
on the phone; the phone then contacts the TFTP server directly. If the TFTP server is not found, the user
is prompted to enter a TFTP server address.
You can also assign an alternate TFTP server to use instead of the one that DHCP assigns.

Request the configuration file. The TFTP server has configuration files, which define parameters for
connecting to Cisco Unified Communications Manager and other information for the phone.

Contact Cisco Unified Communications Manager. The configuration file defines how the Cisco DX650
communicates with Cisco Unified Communications Manager and provides a phone with the load ID. After
it obtains 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 the security profile of the phone is configured for secure signaling (encrypted or authenticated) and the
Cisco Unified Communications Manager is set to secure mode, the phone makes a TLS connection.
Otherwise, the phone makes a nonsecure 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 autoregistration is enabled in Cisco Unified
Communications Manager, the phone attempts to autoregister in the Cisco Unified Communications
Manager database.
Autoregistration is disabled when you configure the CTL client. In this case, you must add the phone to
the Cisco Unified Communications Manager database manually.

If the phone is booting for the first time, display the
Welcome
screen and run the Setup Assistant.
