■ If you select the next button, you can select either or both of the
following conditions:
If you select Call Forward Busy, calls will not ring at all when all of
your lines are busy and will be immediately forwarded to the extension
or external phone number you specify in the box.
If you select Call Forward No Answer, calls ring the number of times
you specify in the rings box. If they are not answered then, they will be
forwarded to the extension or external phone number you specify in

Call Forward
Precedence
Five features can interact to affect call forwarding: Forward to Mail, Call
Forward No Answer, Call Forward Busy, Call Forward All, and Do Not
Disturb. If they are enabled at the same time, the NBX system determines
precedence, which call forwarding path is in effect, according to the
following rules:
■ If Call Forward All is enabled, all calls are immediately forwarded to
the Call Forward All destination. All other feature settings are ignored.
■ If Do Not Disturb is enabled and Call Forward All is not enabled, all
calls are immediately forwarded to the Call Forward Default
destination. All other feature settings are ignored.
■ If Call Forward Busy is enabled and Call Forward All and Do Not
Disturb are not enabled, all calls received when this extension is busy
are immediately forwarded to the Call Forward Busy destination. All
other feature settings are ignored.
■ If Call Forward No Answer is enabled and Call Forward All and Do Not
Disturb are not enabled, all calls received when this extension is not
busy are forwarded to the Call Forward No Answer destination after
the specified number of rings. All other feature settings are ignored.
■ If Forward to Mail is enabled and Call Forward All, Do Not Disturb, Call
Forward No Answer, and Call Forward Busy are not enabled, all calls
received when this extension is not busy are forwarded to the Call
Forward Default destination after one ring.
