Device, as with Amazon usual, delivered within 24 hours.. After unpacking, loading and the Speedport W724 logged. Everything without problems. Device set, taken from contacts Speedport and Los phone. Super clean, noise-free reception. Was totally surprised. Do not understand here some opinions about this product. Can someone explain that some wrong router, or simply have no idea of the installation of the article have only. Battery needs to test, but so far makes great impression on hold. Can this product to anyone who wants to have a good IP telephone. I would buy it again.
