I have previously thoroughly well-read and had then deliberately opted for this model, since the DSL Taglichkeit is also confirmed by the manufacturer, which unfortunately is lacking in many other large and well-known brand manufacturers, or is only confirmed insufficient. It then reads very frequently in forums or reviews that the OB protection sockets (framing) can not operate with a Fritz box or that basically the line in such a way to its knees that dialing (registration) the respective provider no longer works or constantly comes to crashes. Did they then even his phone over DSL running, then discussions would also be more bad than good. The big brands familiar to everyone, so I will not mention the names here. However, the fact is, unfortunately, that one would expect from this quality normally but also save you more and more to it, and can be produced cheaply in Asia and just grab it their label. Here you should therefore buy only after thorough research, because some products are still good even from these well-known brands, but it is no longer at all.
This product now from Phoenix keeps its promises. No call terminations and so far no restrictions when surfing the Internet, since the damping fails less and also better protection is built in, like you would with other products. A clear "top recommendation" from me
