One of the best phones that exist on the market. An assistant program the phone sets up. Connects to immediately through the router to the Internet. Connection to the PC immediately possible. Backup unfortunately only possible via network address. That's completely inconvenient and not practical. Bluetooth binds only a more Haedset not. Phonebook from the mobile phone only on PC and i Tunes and then to Outlook possible. The own behavior to better discuss before purchase with Gigaset. Otherwise possibly disappointed. It's either ISDN or VoIP. All together can not. Unfortunately. The phonebooks of the Internet described not settle down automatically. Here Softwareupdats necessary. So is just beginning. Phonebook has 1000 entries un suitable handsets have 500 '. Is not it. Complete Fehlkonstruktion so. My Phonebook order copies do not complete. Other handsets than the supplied ones, not compatible. Unfortunately. A 2000 telegonspeicher or more would be desirable. USB stick for a backup should be available at the price. So here we must urgently rectify. Minimum an automatic backup when connected to the PC in its own database. Other Snbiezer are unfortunately even worse. Unfortunately. Bad this market. Nice turn as connected to the Internet, the called party is displayed with full address. Unfortunately, you can not save him, only the telephone number called. Well let's see if they change the software a bit.
