Your phone must be connected to a network and configured to connect to a call control system. The phones
support many functions and features, depending on the call control system. Your phone might not have all
functions available, based on the way your administrator has set it up.
When you add features to your phone, some features require a line button. But each line button on your phone
can support only one function (a line, a speed dial, or a feature). If your phone's line buttons are already in
use, your phone won't display any additional features.
To check which phone model you have, press Applications and select Phone information. The Model
number field shows your phone model.
