You can interact with the features on your phone in several ways:
Soft Keys located below the screen, give you access to the function displayed on the screen above the soft key. The soft keys change depending on what you are doing at the time. The "More ..." soft key shows you that more functions are available.

Using Busy Lamp fields
A Busy Lamp field lets you see if colleagues' lines are free to take calls.
You can have up to 8 Busy Lamps on the Cisco 8841/8851 and 8861, all programmable through the Gamma Horizon Portal. The line button is green if it's free or red if it's not.
The Busy Lamp field also acts as a speed dial, letting you call your contact via a single button.
