I want anyway violently oppose all one-to-two-star reviewers: The MT-F offers an impeccable telephony sound quality (which I only on a VoIP connection of the Telekom and with a FRITZ! Box 7330 [...]! have tested); as rushes, echoes or buzzing nothing. In conjunction with the Jabra corded headset can be while making calls hands free for other activities have (in this case would be an idea to AVM for the next firmware update that the key lock function turns on even during a call - then you can phone a little careless stuck in your pocket).
The phone directory can be on a PC or in the phone unit to manage and then to all of the FRITZ! Box registered FRITZ! Fon devices available. Similarly, can the FRITZ! Box internal answering machine operate smoothly on the handset.
Very elegant, I find that the WLAN function of FRITZ! Box can be switched on and off via the handset - this function I do not want to miss.
The battery lasts in average operating by several days to a week and is also recharged quickly. The DECT range is absolutely sufficient over the two floors of our house.
We are certainly still one or two buy us more MT-Fs to the old Orchid-hand parts (by the previous phone still on the FRITZ! Box are in use) replace.
Conclusion: A (as of AVM otherwise be expected) well thought out and easy to use device that is perfectly suited to working with the FRITZ! Box. Unique buy recommendation!
