8.2 Call Appearance Buttons
Call appearance buttons are used to display alerts for incoming calls directed to a user's extension number or to a hunt
group of which they are a member. Call appearance buttons are also used to make outgoing calls.
By having several call appearance buttons, a user is able to be alerted about several calls, select which call to answer,
switch between calls and take other actions.
When all the user's call appearance buttons are in use or alerting, any further calls to their extension number receive
busy treatment. Instead of busy tone, the user's forward on busy is used if enabled or otherwise voicemail if available.
Call appearance buttons are the primary feature of key and lamp operation. None of the other appearance button
features can be used until a user has some call appearance button programmed
