Call waiting allows IP phones to receive a new incoming call when there is already an
active call. The new incoming call is presented to the user visually on the LCD screen.
Call waiting tone allows the IP phone to play a short tone, to remind the user audibly of
a new incoming call during conversation. Call waiting tone works only if call waiting is
enabled.
The call waiting on code and call waiting off code configured on IP phones are used to
activate/deactivate the server-side call waiting feature. They may vary on different
servers.
