The additional services such as radio and e-mail work, but are not used.
Phoning works without problems (Fritz box 6360 of cable Germany) and also the use of the Fritz box answering machine is working fine.
There are only four stars because the hands-free quality of the phone is not convincing. Whether you use the loudspeaker during a call or when listening to the ABs: It sounds so tinny that speech intelligibility suffers at the lowest volume.
Furthermore bother me a few details of the headset function. I use my smartphone to a high-quality in-ear headset (Beyerdynamic MMX 100) to make calls and listen to music and was hoping for a similar usage at FritzFon:
Music: Internet radio stations sounds rather dull and matter is, I suppose, only mono.
Phone: The voice quality and -verständlichkeit is terrific (especially in HD calls). Unfortunately, no ringing signal is output from the headset and the headset key, usually assumed / hook or mute can be switched with, has no function.
Apart from these two caveats I am fully convinced of the phone and will also replace the FritzFon MT-F every other DECT phones.
