nice part, but not everything is harmonious ... Update needed !!

Since the beginning of September I have the Fritz Fon after my Gigaset has given up the ghost after only 4 years.
The Design is MT-F We really like. The controls are also quite enjoyable. Emails can be received and
. Send In addition, it indicates new mail, even though the PC is switched off.
What I do not like:

Unfortunately, all predefined ringtones are really terrible. Why you can not have their own sounds on
Upload the Fritz box? Although the Fritz box is in the same room, is often significant cracking and noise
be heard during a call. Something I do not know from Gigaset and this is one off via update.
In addition, you can hear now and then something like an echo when talking, like Voip telephony with low bandwidth.

Here AVM must urgently rectify !!
