FRITZ!Box Fon WLAN provides many PBX features,
including call waiting, call forwarding, three-
party calls, and more, both for fixed-line and for
Internet calls. The combination of fixed-line and
Internet telephony permits new uses, such as
the call-through function to permit calls over the
Internet from mobile phones. Furthermore,
FRITZ!Box Fon WLAN supports convenient phone
line features, both over the fixed-line and over
VoIP. Features supported by SIP include three-
party calls (3PTY), external call transfer (ECT), call
diversion, and message waiting indication (MWI).

FRITZ!Box Fon WLAN is also available with an
additional ISDN S0 NT interface with which exis-

ting ISDN telephones or PBXs connected, thus
making those devices VoIP enabled.

FRITZ!Box Fon WLAN connects one or more com-
puters to the ADSL line – simply and securely –
through a USB or LAN cable or wireless via WLAN.
The built-in firewall adds security to high-speed
surfing. FRITZ!Box Fon WLAN works either as an
ADSL modem or as a modern router to enable
simultaneous surfing from several computers.
Other network devices can also be connected to
FRITZ!Box Fon WLAN including game consoles,
network switches or IP telephones. Its built-in NAT
firewall capabilities protect against unauthorized
access from the Internet and factory-activated
encryption prevents intruders accessing the WLAN
network. Features such as easily configured port
forwarding and traffic shaping for optimized use of
bandwidth add additional value.

TÜV-certified security 

FRITZ!Box Fon WLAN provides optimum quality of
service and performance through integrated band-
width management. This advanced router function
monitors incoming and outgoing data traffic over the
ADSL line and ensures that telephone communica-
tion over the Internet is not impeded by simultane-
ous web surfing. All uploads and downloads are
adjusted to the remaining available bandwidth. In
this way, multiple Internet phone calls can be con-
ducted simultaneously without any interference.
