Only small problem: no syncrho address books, making it necessary to make double entries (fortunately I have some numbers to enter).
Same signal level "missed call": no sync between handsets when we checked out one of the two.
It repeat the manipulation 'on the second.
Apart from these small flaws (at rest with the Freebox?), I have no complaints about these phones.
Quick and easy installation.
Works perfectly well DECT method (due to my purchase).
