Configuring the System
Call Forwarding
The call forwarding input screen depends on the type of call forwarding selected ("in
the exchange" or "in the communications system").
Call forwarding in the communications system(Anrufweiterschaltung in der
Anlage)
When calls are to be forwarded in the communications system, you specify a call for-
warding destination for incoming calls to each of the connected terminals.
If calls are forwarded to an external destination, both B-channels are busy for the
duration of the outgoing call; the connection is thus busy. Call charges incurred for
the forwarded call are billed to the line from which the call was forwarded.
You have the following options:
Call forwarding immediately(Anrufweiterschaltung sofort): every incoming call is
immediately forwarded to the given destination.
Call forwarding after a specified time(Anrufweiterschaltung nach Zeit): the call is
forwarded to the given destination if the terminal called does not lift the handset
within approx. 20 seconds.
Call forwarding on busy (Anrufweiterschaltung bei Besetzt): if the terminal called is
busy and call-waiting protection is active, every further call is forwarded to the given
destination.
