System Phones with ISDN

Many performance features are selectable and can be activated in different ways. This can be done via the service menu, the scroll keys during the call or the dial numbers. Don't be afraid to try all the keys. You can always bet back to the initial state without saving via the service key. The display should be read as a step-by-step instruction. Confirm questions with the 'checkmark' key. Arrow symbols to the left or right show further menu items. Follow those arrows with the arrow keys.

Determined call forwarding (incl. timed forwarding)

With the determined call forwarding a determined forwarding target can be saved permanently (until deletion of the target) in the end device.
