Viewing Security Information

•CTL File—Displays the MD5 hash of the certificate trust list (CTL) file that is installed in the phone, and provides access to the CTL File menu. If no CTL file is installed on the phone, this field displays Not Installed. (If security is configured for the phone, the CTL file installs automatically when the phone reboots or resets. For more information about this file, see

Cisco Unified Communications Manager Security Guide.)

–	A locked padlock	icon in this option indicates that the CTL file is locked.
–	An unlocked padlock	icon indicates that the CTL file is unlocked.

•CAPF Server—IP address of the CAPF server used by the phone. Also displays a certificate icon if a certificate is installed for this server.

•Communications Manager/TFTP Server—IP address of a Cisco Unified Communications Manager

and TFTP server used by the phone. Also displays a certificate icon if a certificate is installed for this server.

If neither the primary TFTP (TFTP Server 1) server nor the backup TFTP server (TFTP Server 2) is listed in the CTL file, you must unlock the CTL file before you can save changes that you make to the TFTP Server 1 option or to the TFTP Server 2 option on the Network Configuration menu. (For information about changing these options, see “Configuring DHCP Settings” section on page 5-5.)

Note When the wireless IP phone is connected to a Cisco Unified Communications Manager Release 5.0 or later, you can have multiple security profiles assigned to a phone. When the phone has more than one security profile using different secure Cisco Unified Communications Manager clusters, you must delete the CTL file from the current profile before enabling another profile. See “Understanding Security Profiles” section on page 1-13.

To unlock the CTL file, follow these steps:

Procedure

Step 1 If a CTL file is installed on the phone, choose Settings > System Configuration > Security > CTL File. Step 2 Scroll to the CTL File menu and press Select.

Step 3 Press **# to unlock options on the CTL File menu.

Step 4 If you decide not to continue, press **# again to lock options on this menu.

Step 5 Scroll to the CTL option that you want to change and press Erase.

After you make the change, the CTL file locks automatically.

Step 6 To exit the CTL File screen, press the Exit softkey.

The Trust List screen displays information about all of the servers that the phone trusts.
