The unit arrived today, unpacked, connected and .... because he has actually brought via DHCP without much fumbling in the configuration smooth to an IP address. I have never seen in any of the previously purchased IP phones. For this high praise. If basic knowledge in the fields of SIP networks and called his own, the configuration via browser is feasible, registered at the Fritz box a new phone device, the device registered at the Fritz box with the new data, ready. Can be used in five minutes. The voice quality is clean and still a plus, the device has two different headset interfaces, both of which function properly. So you have the wide range of headsets. Phonebook can be administered via a web browser, an additional advantage. So far so everything top, so five points. If the price almost all wishes are fulfilled.
