Hi... New to 3CX and just getting to know it. I was able to download a 3CX softphone to my notebook. And it hooks up with my voip provider. Able to dial and receive calls. Rings at both parties. Only problem is the is no sound or microphone either way. I can't talk or hear. Niether the person who receives my call. Since I am a newbie am I missing to configure something? I am running Windows 7 Home on the notebook. Suggestions from you guys would be fantastic.
