HiNow again today calling any viber out contact fails right away.So far here in June viber out intra DK calls to Danish landline and mobile numbers have not been possible for several days - 3 complete outages.I have made tickets each time, but never received any solution - tickets just closed without explanation or response.So I certainly can not recommend viber out and I will switch to another deskphone on windows and iOS.Br Peter L
