Question about Panasonic Kx-Prs110

Silvanas' answer is not correct. Both are DECT (even if Digitec does not show this on the page).
The real difference between the Panasonic KX-PRS120 and KX-PRS110 is that the former has an integrated answering machine. See: https://schnurlostelefon-test.org/panasonic-...

The difference is that the more expensive KX-PRS120SLW model has DECT (Digital Enhanced Cordes Communication). With this - as far as I know - one achieves higher ranges (distance from handset to station) and can use several satellite stations in the same number range. I don't know what else DECT can do. But I think that if you just want to make calls at home, the cheaper KX-PRS110 model is perfectly adequate. (Don't forget: after connecting to the router, reboot it first so that the new phone can be identified. That's what I did when I installed the KX-PRS110 on the Swisscom router).

I hope this information has helped.
