SETUP
Even though it's been a while since we reviewed an FRITZ!Box the setup procedure is the same so after you connect it to your system just launch your Internet browser to start it (if that doesn't work automatically then go to http://fritz.box or 192.168.178.1).
The setup wizard will first ask you to choose your preferred language and of course your region.
Next step is to choose your annex mode (A or B), agree (or not) to sending back error reports and diagnostics data and ISP type.
Finally you will be asked from the setup wizard to setup your VoIP numbers as seen above after which it will take a couple of minutes to check your settings and verify the internet connection.
