Call quality lousy - the worst AVM product that I had previously

The DECT Repeater can be at the Fritz box 7490 quickly and easily set up, so as one is just used by AVM.
The DECT range is significantly enlarged. At places where I used to the DECT repeater or no
had a very weak signal, was the signal reception after installing the DECT repeater good to very good.

However, the reception of a signal enough - if you want to call - not from. And here comes the criticism. The voice quality
when using the AVM DECT repeater is beneath contempt. Absolute time on your side, sometimes on the side of the interlocutor
intolerable and unacceptable. Unfortunately, I have tried for too long to optimize, so now I can no longer return the device,
what I would otherwise make immediately.
