Some menu options are dynamic and only appear when appropriate. For example, the Features menu cannot be accessed when the phone is locked. Access to other menu options is controlled by your system administrator. They can set system wide rules for which options phone users can access. They can also set specific rules for each phone user.

Even if you are restricted from accessing an option, it may still be applied for you by your system administrator. For example, the system  administrator may configure call forwarding settings for you.

The system administrator can control your menu access to the following groups of functions:

Basic Call Functions
Controls whether you can access the phone's menu options for call pickup, park, unpark and transfer to mobile functions.
Advanced Call Functions
Controls whether you can access the phone's menu options for do not disturb, account code, withhold number and internal auto-answer functions. In addition, the Account Code menu is only shown if the system has been configured with accounts codes.
Forwarding Functions
Controls whether you can access the phone's menu options for forwarding and follow me functions.
Hot Desk Functions
Controls whether you can access the menu options for logging in and out.
Passcode Change
Controls whether you can change your login code (security credentials).
Phone Lock
Controls whether you can access the menu options for locking the phone and for setting it to automatically lock.
Self Administration
Controls whether you can access the Self-Administration menu option.
Voicemail Controls
Controls whether you can access the Visual Voice option through the phone's Features menu. Your system administrator can also disable the Messages button from accessing the visual voice menus.
Group Controls
The system administrator is able to configure if you can access the Membership, State and Fallback options of a group. If you are not configured for any groups then the Group menu is not shown.
Mobility Controls
The Mobile Twinning options are only shown if you have been configured to use mobile twinning.
System Administration Controls
The System Admin option is only shown if you have been configured as a 'System Phone' user.

 

Note that restricting menu access does not restrict access using available short codes and programmable buttons. However, those can also be removed or added by your system administrator.
