Constant crack in the pipe. There's a star still too much.

Why not get the AVM go? When you make a call in the area of ​​the repeater hears the distant interlocutor permanently at very short intervals pops. And I have extra-AVM phones FritzFon C4 bought to remain compatible.
The support of AVM knows no remedy although my repeater has already twice changed. All other sources of error were excluded. I am at a loss, and now also increasingly angry about the incompetence of the manufacturer AVM in his own DECT technology.
AVM should its energy use that it can be telephoned properly before re any additional features to be programmed that the problem persists.
In retrospect, I regret that very I switched from my old Siemens Gigaset system (with matching Gigaset repeater). So there were no problems.
