Super suitable for all those who can not deal with electronic devices ...

... For example the elderly. Much simpler and clearer to use it no longer is. Works flawlessly.
Only the installation was a bit difficult - for Austria the cable did not come with the mating plug. Did not fit into the Austrian jack. Have only need to call the technical support of Tiptel - then there I got the decisive tip on how I can work around the problem by hanging telephone and answering machine together.
Overall, the device is but really great!
