If you find thissecond ring distracting, you can have the system prevent a secondcall from disturbing you by assigning Do Not Disturb (DND) on Busyto your extension.When DND on Busy is turned on for the set, internal and privatenetwork callers hear a busy tone instead of ringing when you are onthe telephone. External callers are transferred to the prime set usedin your system.For step-by-step instructions, see “Change the Do Not Disturb onBusy feature” on page 25.If you use DND on Busy, the line indicator for an external incomingcall still flashes, but your telephone does not ring.Forward on busy takes priority over DND on Busy.If an external call uses a target line, the call will be processedaccording to the programming of the target line.
