Call Diversion on the ISDN Line
FRITZ!Box Fon WLAN 7270 79
Call Diversion 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 network provider and cannot be
used to forward calls to Internet numbers.
In addition to call forwarding, there is also call diversion
via FRITZ!Box. Use this kind of call diversion to divert calls
to internal and external lines. See the section “Call Diver-
sion” on page 84 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.
