hello zämä, As I have recently changed my internet: Copper to glass, my HD Davos (Swisscom product https://www.swisscom.ch/de/privatkunden/hilfe/geraet/festnetz-ip/hd-phone-davos.html) are currently no longer working. The current supplier told me that we use landline phones with a HomeBase. So the question is: is this Duo product the right one? What should I generally look out for when looking for landline telephones from you that are equipped with a HomeBase (not mentioned anywhere - HB)? Merci and regards
