My hope was to connect the handset via DECT with the Fritz box to have to put not a new cable, but then BT works as I said no because it runs on its own base station and not using the handset.
The phone directory could be easily transferred from the phone, but an entry for each number (and not per name) stored in the handset. This makes it hard to handle the large number of entries. Search can be in the phone book with the first three characters of the name.
It's a shame that despite local storage of mobile phone phonebook, on this there can be no reefs, unless BT connection to the cell phone is. Then only the phone book of the household connection can be used.
The earpiece rattles slightly (but understandable), the voice quality with the interlocutor but is clear and good.
The range of the BT surprised me, even through walls and basement ceiling, the signal easily. Here I had with headsets constantly crashes.
When talking on a channel (house connection o. Mobile) and on the other is a conversation, this is indicated visually and acoustically. You can switch between the calls, which I find very convenient.
Feel of the handset is OK, it is very easy. The illumination of the display and the keyboard is uniformly and sufficiently. Even with many phone calls I get loose during the day on a single charge, the evening it goes into the station.
I do not know what functions the Fritz box "Blacky" meant, in my 6360 works but as the message of the Fritz box on the handset that on the AB is a message. That's enough for me ...
For the price a strong buy recommendation!
