... For each Fritz box owner. The Firtz Box is already an ingenious multifunction router if there is also still a FritzFon this I get really into raptures. The features are well thought out and the combination with the box a dream ... I would like to highlight the seamless integration of a mobile phone address book, which for me personally is very important. In addition, the phone is comfortable to hold, the voice quality is very good and the battery lasts a long time .... Highly Recommended and unbeatable in combination with the Fritz box !!!
