Have the phone number of years. In connection with the Fritz box 7270. It works almost always (almost) well. The initial installation was simple - BUT! In an emergency, I would like to rely on this phone is not. It chooses not often, it "takes off". I'm not a technology person, simply said: It is not often ON. And when my heart patient is too risky. When I try to initiate an emergency call, then this phone is not what I want! I trade it out!
