Hello all, I can't make calls using the windows client and a snom 320. It works perfectly using the 3cx Web client. When I double click a contact or extension, the client just moves to the call screen and does nothing. I have tried this using a Panasonic sip dect phone from the same client and it works fine. It is not a firewall issue. Latest versions of 3cx, client and Windows 10 and the latest version of the snom firmware downloaded from 3cx. Anyone have any pointers? Thanks.
