FRITZ!Box Fon WLAN makes telephoning over the Internet as easy as you'd like it to be: connect your existing telephones; pick up the receiver -- that's all! Now you're talking over the Internet with Voice over IP -- without turning on your PC, and without changing your phone number. And FRITZ!Box Fon WLAN also puts your PCs on the Internet at ADSL speed -- over Ethernet, USB or wireless LAN -- always with firewall protection, and with wireless encryption activated out of the box.
