Sorry, only 3 stars. Maybe it would have been more if I had used the phone right at the main port, because the phone actually brings with everything a "normal" telephone may need. However, I use it only as a second unit, registered as a DECT telephone to a Fritz Box 7330th This then acts as a base station. Problem: This eliminates some of the comfort features of the phone. Call list, for example non-existent. The button below the display "Call" will not work and jumps pressing repeatedly on "contacts" back. The call list, I would have to see through the browser interface, my Fritz box. Also None: Flashing at incoming calls. (My meantime defective Aldi-cheap part had at least a detailed call list and could even blink. The problem of the lack of comfort does not lie primarily on the router, but the phone itself). Others can do so better with some benevolence. What does not work: The much-vaunted ECO mode I can not adjust. Hat according to instruction four stages. In my case as DECT only one, namely the factory setting with the highest transmit power. I just hope that at least the transmission pulses are reduced at rest. As for the battery consumption, I'm almost convinced that the device continuously transmits at peak performance, because after only 3 days in stand-by that thing was empty again. The connection to the base (in my case, as I said the Fritz box) is a moody player. The router is in the basement and has to chase his strength through two storeys. In the case of my initial phone (Panasonic) which works perfectly, even at reduztierter transmission power. Here the sinus it cracks questionable, so I think every time, regardless of losing the call. After all, the voice quality is of the Panasonic superior (clearer voice, natural sound, a total of a little louder and clearer). Processing for the price is more than good. It looks more expensive, as it is. Crisp, neatly defined pressure point of the keys, optionally with key tone. However, only 3 stars, since central functions (call list, ECO, battery power) are not to be used as DECT.
