Phone Settings Overview
Cisco Unified IP Phones include many configurable network and device settings that you may need to modify
before the phone is functional for your users. You can access these settings, and change many of them, through
menus on the phone.
Cisco Unified IP Phone Menus
The Cisco Unified IP Phone includes the following configuration menus:
•Network Configuration: Provides options for viewing and making a variety of network settings.
•Device Configuration: Provides access to sub-menus from which you can view a variety of non
network-related settings.
•Security Configuration: Provides options for displaying and modifying security settings.
Before you can change option settings on the Network Configuration menu, you must unlock options for
editing.
You can control whether a phone user has access to phone settings by using the Settings Access field in the
Cisco Unified Communications Manager Administration Phone Configuration window.

Display Settings Menu
To display a configuration menu, perform the following steps.
You can control whether a phone has access to the Settings menu or to options on this menu by using the
Settings Access field in the Cisco Unified Communications Manager Administration Phone Configuration
window. The Settings Access field accepts these values:
Note
•Enabled—Allows access to the Settings menu.
•Disabled—Prevents access to the Settings menu.
•Restricted—Allows access to the User Preferences menu and allows volume changes to be saved.
Prevents access to other options on the Settings menu.
If you cannot access an option on the Settings menu, check the Settings Access field.
Procedure
Step 1 Press Settings to access the Settings menu.
Step 2 Perform one of these actions to display the desired menu:
•Use the Navigation pad to select the desired menu and then press the Select.

If a Settings Menu password has been provisioned, SIP Phones present an “Enter password”prompt after
you enter **#.
Note
Make sure to lock options after you have made your changes.
Do not press **# to unlock options and then immediately press **# again to lock options. The phone

Value Input Guidelines
When you edit the value of an option setting, follow these guidelines:
•Use the keys on the keypad to enter numbers and letters.
•To enter letters by using the keypad, use a corresponding number key. Press the key one or more times
to display a particular letter. For example, press the 2key once for “a,”twice quickly for “b,”and three
times quickly for “c.”After you pause, the cursor automatically advances to allow you to enter the next
letter.
•To enter a period (for example, in an IP address under IPv4 Configurations), press the .(period) softkey
or press *on the keypad.
•To enter a colon (for example, in an IP address under IPv6 Configurations), press the : (colon) softkey
or press * on the keypad.
•Press the << softkey if you make a mistake. This softkey deletes the character to the left of the cursor.
•Press Cancel before pressing the Save softkey to discard any changes that you have made.
The Cisco Unified IP Phone provides several methods that you can use to reset or restore option settings,
if necessary.
