Function well, housing quality medium, bad speakers

We have the phone for a few weeks at home in operation. The usability is excellent, the call quality on the handset properly, the phone runs without interference. However, already now the listener begins to creak slightly at what may well disrupt the phone, and the quality of the speaker is still very modest, which interferes in speakerphone and possibly also when listening to the answering machine! Nevertheless - a total of four stars because it is a complete package.
