3.5.5.1 Call forwarding in the device
• The device connects the calling subscriber with an internal or external subscriber you
have specified.
• Call forwarding between the subscribers is possible in the call assignment.
• Internal call forwarding is always switched in the device. The device automatically detects
whether the call destination is internal or external. In the case of external destinations, a
B-channel of the ISDN connection is always used.
• The call on the terminal that set up call forwarding for the telephone number (MSN or
PBX extension) is forwarded. Other terminals that have the same call alloca-
tion continue to be called.
3.5.5.2 Call forwarding in the exchange
If you use e.g. T-Net-Box, call forwarding must be carried out directly in the exchange.
Call forwarding on the PBX connection
If call forwarding is set up by a subscriber and this can be carried out by the exchange, all
other device subscribers can continue to be called.
Call forwarding on the point-to-multipoint connection
If a user has set up call forwarding for an MSN and this can be carried out by the ex-
change, the other extensions in the call sharing will not be called for this MSN.
Note
Existing call forwarding (CF) should be deleted before new call forwarding settings are
made. Two call forwarding options can be switched simultaneously. For example CF if
telephone number 12345 does not respond and CF if telephone number 45677 is
busy.
A user has

not signalled and is instead immediately forwarded to the external number. If the call for-
warding is set up for

, the called extension will ring for the configured time and
the call will then be forwarded If the exchange rejects forwarding, the call is set up as for
call allocation.
There are three options for call forwarding:
