How to use Line Keys on the Cisco 8841, 8851 and 8861 IP phones
In this guide, we explain everything you need to know about Line Keys on Cisco 8800 series VoIPÂ phones.
You can interact with the features on your phone in several ways:Â
Soft Keys
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.Â
Feature and line buttons
located on either side of the screen, give you access to phone features and phone lines.Â

The Busy Lamp field also acts as a speed dial, letting you call your contact via a single button.Â
