Clear, delivery as always quickly. I can only say about the Box: Everything works without problems and the conversion from ISDN to VOIP Telekom worked without problems. You do that, what it should: run without problem. After 7050 the second Fritz box. Do not know what should be better. Perhaps a small limitation that but not so relevant for me, the transmission strength! There are boxes, which have a longer range. But for me no problem and that I may not "contaminated", I drossele even the power and turn on at 24:00 clock off completely wireless. Even smart phones I use and can be customized with the Fritz software running very well. all good.
