AVM - very disappointed

Initially, the phone made a good impression. It lies are easy to install, looked good and had to offer interesting features.
The latest update was installed instantly without any problems.

The first talks were satisfactory. I tried to improve the voice quality by switching the equalizer. A treble boost brought miserable results, so everything again adjusted linearly.

The vaunted HD quality in my opinion is at the moment just a marketing gimmick. First, it only works over IP telephony, and even if the called party also used this phone.

But for good reason I use continue my ISDN telecom connection with its advantages.

Final "Off" for Fritz! Fon but came when I wanted to call in the garden, and hum and noise disturbed the conversation. Then the connection is completely broken and we had to make phone calls using landline. The called party received the message placed participants.
The distance to the Fritz! Box 7270 was only about 7 meters in the house and 7m free field. Since, any old mobile phone, as already described several times, afford better.
Since no update regarding the coverage which can cause - everything back to Amazon.
