I bought the phones (3) as extensions for my practice. They look really chic on the wall of work well. Wall mounting is not worth talking about-there are two holes and are hung on two screws. Sits well and nothing wobbles. Since the phones hang on an old Eumex plant, which is coupled to the door opening, it looked just like this as if this does not work with it. But then I quickly noticed that only the pause time the R button in the default setting was too long. In the menu I could put down in no time at 100ms and now also works the doorway of the phones. The only downer (and star deduction): The ringtones are really annoying. In this day and age can be without effort better and play a few more notes on the chip. Philip has it probably hundreds of thousands. This could have been done better. Otherwise: Chic and functional - Recommendation
