After a bit of googling was a possible cause: DECT phone.
I could only do not believe, I then but the base station Gigaset A600 just took our time from power.
Behold - error away.
But now it was not an option to convert the phone, the connection is just times where he is.
After replacing the existing connection cable through the acquired here, the image quality is excellent again, even if the Base Station turned on the phone.
The promised good shielding I can only confirm.
The cable feels very valuable and stable.
However, if you need a 90 degree corner is here definitely have fun, but this should be previously aware.
The bending radius is very large.
I would buy it again at any time.
