Assigning Internet and Fixed-Line Numbers to
the FRITZ!Box Fon WLAN Extensions
Once you have entered the Internet and fixed-line network
numbers in FRITZ!Box Fon WLAN, the PBX extensions
(“FON1” and “FON2”) initially will continue to react simulta-
neously to all incoming calls. To ensure that the connected
terminal devices react only to certain numbers, assign the In-
ternet and fixed-line numbers to the different FRITZ!Box Fon
WLAN extensions. This also defines the kind of connection
used to conduct telephone connections: the fixed-line net-
work or the Internet.
Perform the following steps:
1. Open the “Telephony / Extensions” menu and click the
“ISDN Numbers” button.
2. Select a number from the “Number of the extension”
drop-down menu in the “Extension FON 1” area. The ter-
minal device connected to the “FON1” extension reacts
to incoming calls placed to this number and uses the
kind of connection specified for outgoing connections
with this number.
3. From the “Additional numbers” drop-down menu, se-
lect any other numbers to which the terminal device at
the “FON 1” line should react for incoming calls.
4. To ensure that the terminal device at the “FON 1” exten-
sion reacts only to incoming calls to the specified num-
bers, disable the option “react to all numbers”.
