Now works finally

I too am one of those who has changed how others here for new telecom IP-based telephone line with DSL. Shortly after the activation already walked the trouble with (thankfully !!) rented Speedport W724 Los: Permanent disconnections when making calls, incoming calls were not answered, outgoing calls did not go through. After 3 months, two technicians visit and about a dozen error messages in the telecom, I then times on a trial basis this Fritzbox connected, and everything went perfectly. Unfortunately, this box must have been a mistake, because after a week they could not establish more Internet connection. However, the exchange on Amazon was hassle. The new spare box also works as it should. Unfortunately, I had bought two speed 10 Phones of Telekom, in the assumption that the telephone would work in conjunction with the Speedport so; Unfortunately, far from it! These phones are speed with the Fritzbox but not compatible! I then bought a Fritzfon MT-F. In combination with the Fritz box a perfect team. I am going to buy yet another Fritzphon for my office.
