I just start to try 3CX system and have no experience with it. I have D-link DPH-50U adapter to connect regular phone to VoIP line. It originally made for Skype and it work with Skype well. But my question is: if it possible to make any settings and use this adapter with 3CX? I add Skype gateway in 3CX settings but have no results. I do not know where is a problem: or this hardware cannot work with 3CX, or hardware is OK but I need to do something to configure it but I do not know how. Any advise?!
