no idea how the positive reviews about this product come about, but I can give to you the following for a detailed test: do not buy this product! In practice, this phone is the absolute seizure, the connection is regularly lost, your name are not available - the beauty of it, you would not even notice, except to the friends do not report at once days ;-) To THE ensure I was forced to put regular check-in calls! No matter what settings and updates - no chance of this phone to steer towards its true destiny!
HD telephony, DECT, VOIP ----> these are features that this device were placed under any circumstances in the cradle. Noise without end, disconnections, poor reception - every "normal" conversation is the windfall.
I now have my Fritz! Box with an analog phone Siemens (Gigaset SL400) combined and can now make calls at last ... the nice thing is, I understand my opponent, no noise, no crack or any disconnections. Screaming I also no longer has to go also so :-) I would also like retired at the point of principle the box, but as everybody knows, there are few alternatives.
Therefore, in summary: if Fritz box, then phone ... Do not only use with a separate / real DECT Fritzbox as Station! So go in practice a lot of nice features lost, but I have now only one modest request: call!
