3CXPhone for Windows – Help
3CXPhone is a Windows application that functions as an IP phone and allows you to make and receive calls using a head set or via the microphone and speakers of your computer.
3CXPhone for Windows is free, although you need to have a VoIP provider or VoIP PBX account from a 3rd party to make and receive calls free of charge or at low cost (depending on the provider). 3CX does not provide such a service. You can find a list of VoIP providers here.
