I bought this phone to take advantage of the DECT function to connect the phone to Telecom Box (Freebox V6 in my case) wireless. If it is possible to connect the 2 DECT, some functions no longer work, including the date and time stamp and thus the calls, which I find very penalizing (you have received a call but when? ??). I do not know if the caller ID works or not once inquired directory (the caller is displayed correctly). The seller offered me a return to his apères-sales service for analysis, but I just think that the product simply loses these functions when connected with DECT in the Freebox V6 which then replaces the original database of the phone. The only way to have the date and time is to maintain the link between the phone and its home base and connect it by wire to the Freebox. Apart from that the phone is: its okay (but a little metal with qq parasites, perhaps due to my line), speaker / handsfree, backlight, large buttons, display the number of messages on answering machine .
