The support (e-mail) is not really ready to think about a problem and feeds the customer off.

The latest Fritz boxes cannot properly VPN. Access from Windows computers is not possible, the remote access software leads to a blue screen in Windows 10. The software has not been updated since 11/2018. For Win 8.1, AVM even recommends using software from 06/2013.

If DECT telephones from other manufacturers are registered with a FritzBox (tested with 7430 & 7530), internal calls are only possible with an artificial pause of around 6 seconds after picking up.

AVM is interested in a Shice for the needs of its customers, but innovation is unfortunately not the case. The FritzFon C6 is a C5 in a different housing with a little more battery. Bluetooth cannot (still) do it.

DNS over TLS does not work correctly with FritzOS 7.21 either.

Finally, the cracker: AVM prohibits the private developer of the "FritzBlock" tool, which among other things Call spam blocking for the Fritzbox enables the use of the name "Fritzblock". How can you actually be asi?
