Instead, the call will be handled in one of these ways:
• If Call Forward on Busy is programmed, the call will ring
if a free key is available. Otherwise, it goes to the Prime
set. DND Busy programming is ignored.
• If Call Forward All Calls is programmed, the call will go
to the Prime set.
• If Call Forward No Answer is programmed, the call will
continue to ring at the destination.
Note: If a terminal rejects a call, the call goes to the Prime set,
if a Prime set is configured for the target line. If the
target line is configured to send a busy tone, the call
gets released with the reason as User Busy.
