I had been an external DECT phone to my Fritz box 7390 and has been repeatedly pointed out that this phone prosperous outs in voice transmission. Because the part was already nearly 15 years old, I have to replace the M2 FRITZ! Fon ordered. Who needs battery-guzzling color displays I thought to myself and I do not regret the decision. The phone works great, and the availability of data stored on the Fritzbox phone book on the phone is great. The voice quality is very good and I have learned to appreciate the RSS function, tells me the phone but every day anew what is at 20:15 in TV. I know missed no impact selling point and I have also not up for sale .... but since I have this home telephone I catch myself anew every day as I check) Even that I can control some functions of the Fritz box from the phone is awesome. So I can turn on and off, and more on the phone, the guest WLAN. Strong buy recommendation from me, the battery lasts in standby when only gelegendlicher use about a week.
