Nothing to add special. It is perfect and meets our expectation, mainly to stop sales calls that have much longer since we are a responder, although it is on the anti solicitation lists. The phone indicates a No. unknown? The answering machine is triggered. Since then, some no longer call.
Otherwise, very simple, intelligible, assignable ring at No. known ... I have not yet found any defects.
Better than Siemens, Sagem, Panasonic I had far ... In 20 years, I'm trying other brands, I return to Philips telephony.
