Are you wondering if your Internet Service Provider (ISP) in Germany supports advanced features like voicemail-to-email or FritzBox routers? We've compiled a comprehensive list of ISPs in Germany to verify:
Since August 2016, the so-called "Routerzwang" (router compulsion) has ended in Germany. Thanks to a new legal regulation known as "RouterGesetz" (Router Law), end customers can now decide for themselves which router they want to use with their broadband connection.
The vast majority of German ISPs publicly display their compatibility with FritzBox routers on their websites and in their technical documentation.
It's crucial to understand that Germany has completed its transition from traditional circuit-switched technology to IP-based networks. This shift was finalized in 2020 with the decommissioning of the last ISDN exchange.
To find out if your specific Internet Service Provider supports FritzBox features, please refer to our detailed list below. This list includes all German ISPs and their level of support for Fritz!Box routers and related functionalities.
By consulting our comprehensive list, you can easily determine whether your current or potential ISP offers the Fritz!Box compatibility you need.
We currently have a file size limit of 10 MB. Given that most voice messages are encoded with a constant bitrate and a single channel (mono, no stereo), we can calculate the maximum duration of a file using the following equation:
Applying this equation to our 10 MB limit and a bitrate of 64 kbps (commonly used by the iPhone recorder app), we arrive at a maximum duration of approximately 21 minutes and 51 seconds. To easily calculate durations for different file sizes and bitrates, you can use our audio duration calculator.
