If one has a more modern Fritz box, then these phones are a very practical addition, because the phone books are maintained centrally via PC in the Fritz box and do not require cumbersome "hooked up" in each handset. Here also the ABs can be konfiguiert and provided. The new handset is charged only once, then it can be connected with the Fritz box in a few seconds. Up to 6 handsets can be added in this way. Allen then stop immediately the phonebooks and ABs are available, numbers and phone books can be assigned to each handset as desired, as well as (self-created) different background Bilder. Individual contacts from the phone book can also be supplemented with pictures. In addition, the handsets are equipped with many additional functions, such as email, RSS news, web radio, you will probably use more often. For those who have a Fritz box, these phones are a clear recommendation.
