Call Forwarding on the ISDN Line
Call Forwarding on the ISDN Line
Call forwarding is performed by the ISDN operator’s swit-
ching station. To use call forwarding, FRITZ!Box must be
connected to an ISDN line. Then this feature can be used
to forward calls to an external line. Call forwarding is sub-
ject to charges by the carrier and cannot be used to for-
ward calls to Internet numbers.
In addition to call forwarding, there is also call diversion
via the FRITZ!Box. Use call diversion to divert calls to inter-
nal and external lines. See the section “Call Diversion” on
page 78 for more information.
For call forwarding you may specify whether you want in-
coming calls to be forwarded unconditionally, after the
fifth ring, or when busy. Different settings may be config-
ured separately for each number.
