The configuration menu is a bit awkward. The VoIP account is set up quickly; tricky it is only in fine-tuning. Here is TP-Link here often to the use of the TFTP protocol - for example, firmware updates and ringtones or phone books. That's in large environments with many such phones certainly useful but exaggerated for use on your home work. The firmware can be fortunately also update via HTTP. Here I consider it useful to use the beta version, since this offers some features more and has better German translation has to offer.
The only feature that I miss is the use of CardDAV phonebooks. So no phone books from Google, iCloud, or ownCloud can be used. However, it is possible to export them and then convert them to a compatible phone for the XML file. If this function should be followed again, I would be very happy - but I think this is relatively unlikely because it is created more for business use with LDAP.
Nevertheless, it convinces with a good ratio of price and performance and stands (for technical reasons) by very short dialing hours but also by an excellent call quality produce.
