It may be that the voice quality is good without a repeater and in the immediate vicinity of the Fritz! Box, but under the circumstances mentioned above, it is with the MT-F hardly possible to carry out trouble-free conversations.
This slight crackling noises in the 10 to 20-second intervals are harmless - really annoying it is when a sudden violent, loud noise from the handset against strikes that can prevent some cases only by ending the call.
We have not (yet) 2 C4 in use. really you should expect all devices ring when an incoming call comes in, but it is not uncommon that a device is not at all upset.
I could talk about other adverse effects here yet.
We are totally annoyed by the Fritz! Fons and surrender it in favor of a proper voice quality like on frills like radio (who does the seriously?), Caller pictures etc.
All proposals from AVM to remedy the problems were here already durchexerziert, just like any other suggestions from the AVM database and from the support hotline.
The coronation is indeed the tip to disable HD voice - with this feature is explicitly advertised.
I have after months of experimentation and exchange of all (!) Other components involved in the coffee when it comes to phones of AVM. In contrast, a boon telephoning with - partly over 10 years old - Gigaset.
