----- Negative:
During a telephone conversation with the finger on the listener again is a quiet "hochfequentes" to hear noise. How disturbing it is felt, is certainly subjective start differently. Yes if AVM is once a loud gimmicks (eg who wants to surf with the DECT phone on the WWW ...) would make improving the audio quality. The speech intelligibility is very benign for the remote site.
The font size is not vergrößerbar- here AMV should think of the Generation 50+ times.
All measures described by AVM help nix. At Swisscom there are entire forums about it.
And it is also definitely not to DSL or cable or IP. For me, the signal goes from an ISDN line directly into the Fritz box and with previous DECT telephones to this port has ever never rushed a.
Addendum 18.1 .:
In handsfree mode, the quality is very good- some callers have noticed right away that instead of the Gigaset is a new phone in use.
When wired headset the original BlackBerry headset works very well.
In handsfree and headset use the mentioned noise does not bother.
Conclusion after a week Verwendung- good buy recommended.
