Doesn’t even turn on without –
Power adaptor isn’t supplied and doesn’t tell you that. Does say in the box that it should be but apparently that’s also not true. Spent an extra £12 on the lead, another 3 days for delivery and still no guarantee the phone will work at this point as should work just via ethernet…but doesnt.

Auch für den Privatgebrauch geeignet
Tolles Telefon mit vielen Funktionen. Die Einrichtung war nicht so einfach wie gedacht, lag jedoch an meinem Netzwerk. Der Klang ist klar, ohne jegliches Rauschen. Das gilt auch für den Lautsprecherbetrieb. Einfache Navigation im Menü und einfach einzurichtendes Telefonbuch.
