AVM Fritz!Box Fon WLAN Review - AVM Fritz!Box Fon WLAN Review


The web interface home page opens with a detailed report on all ports, the Internet connection and uptime and SIP registration status. The Internet section provides an online metering service which is geared up for Internet accounts that are billed on time and usage. You can set rates based on time and accumulated download volume and break the connection or flash the info LED if these are exceeded during the month. For port forwarding you can select a predefined service or create custom entries which can include single ports or ranges and the IP address and port they are to be forwarded to. Wireless security features are extensive with both 64/128-bit WEP and WPA/WPA2 encryption on offer along with SSID masking.

The fun starts with the telephony options and once connected calls can be made over landlines without any further configuration. If devices are attached to both ports they will both ring for an incoming call and either can be used for outgoing calls. Things get more interesting with VoIP in the mix as you can set up dialling rules that will select one mode dependent on the number being called. The perfect example is a call to the emergency services as a default rule automatically causes the landline to be used for this. You can add your own rules which include full or partial phone numbers or ranges and assign them to either the landline or VoIP service. You can also add rules that block access to numbers and ranges if required.

All incoming and outgoing calls and their duration are logged by the router and this applies to both VoIP and the landline. Click on any entry and you can quick dial it and assign the call to one handset. If the Internet connection is unavailable you can force all outgoing calls to the landline and there’s even an alarm clock function that causes one or all phones to ring at a specified time on selected days. Last but not least is a smart Night Service where for a specific time period each day the router will switch off the wireless access point and stop all the phones ringing.


Initially, the Fritz!Box Fon WLAN looks a little pricey but for telephony functions it really takes some beating as it offers a wealth of features you’ll be hard pushed to find elsewhere at this price. Apart from our firmware related problem, we found it very easy to use with all the various options well documented and simple to configure.
