Why do I give it back

First of all - it is very convenient. It basically works.
The feel is not bad, the pressure point of the hard keys, shape and weight of the handset is all ok.
It has a web server, thus allows the phone via a browser to configure.

What I like less:
- The German translation is incomplete (mix of German and English) and the softkey labels are not readable because some of the text is clipped.
- The display has left in my phone from the outset display problems. Streaked vertical lines and Doppler of pixel rows. You could possibly trade for an intact
- It takes the Web server, because the menu in the small display does not go well. The settings are far too extensive - here had a decent sort by necessary master data, extended data and "Now you can set each bit" well done. Thanks to Sipgate, which show the required settings for each device.

BUT:

Once the phone speaker in the earpiece active on I hear a strong background noise. (Before going out a reputation - even at internal tones This is annoying and unacceptable at least for me..
And a phone should always spoken back playing in a weaker volume in the handset (I mean no echo), otherwise it sounds as if one speaks in the "dead space" - as with this phone.
