I had bought this handset to use it as a radio telephone to a Fritz box 7390. However Be commissioning turned out that most phone functions are not available. The time does not adjust automatically, the name of the handset does not appear, not taken the phone book from the Fritz box, ring tones can not be selected from the Fritz box from testing. In short, most of the functions in the setup menu and the menu "Services" are "not available" acknowledged with the message. What for me ultimately the KO criterion is why the phone again goes back to Amazon, that neither missed calls are displayed, are still signaled on the AB is underway calls. Something like this should belong to the basic functions of each phone, which, according to specifications DECT GAP has functionality. The only thing that works in combination Fritzbox / Phillips, is to call and receive calls. The DECT-GAP compatibility with this phone Phillips is far too limited, other manufacturers such as Siemens, it is significantly higher. Therefore strong deductions in the B-Note. The voice quality is, however, good, good menu navigation and easy to read display, so I forgive even 2 stars - at a base station of Phillips of this handset is certainly a good choice as it is to read in previous reviews, but as a handset for base stations from other Manufacturer it is not suitable.
