There are various different ways
of doing this. All call forwarding
options are set
individually for
each line on the respective
terminal
. There are three types
of call forwarding which can be
selected by entering the rele-
vant call forwarding (CF) code
digits.
• Immediate call forwarding
CF code digits “21”
• Call forwarding on busy
CF code digits “67”
• Call forwarding on no reply
CF code digits “61”
In order to use the call-forward-
ing function, your telephone
numbers must be programmed
for the respective analogue line
(see page 17ff).
