Express Talk Softphone
OS: Windows, MacOS
Express Talk works like a telephone to let you make calls through your computer. Call anyone via the internet who also has a softphone installed and if you sign up with a VoIP gateway service company you call regular telephone numbers as well. With Express Talk you could potentially call someone using their internet IP (eg. "bob@1.2.3.4") but this is not usually practical. It is much easier to use a friendly address like "bob@myphoneco.com". To have this you need to sign up with a SIP proxy service. This is almost always free to signup for and usually requires nothing more than an email.

Experience the freedom of choosing your own VoIP provider whenever you want, wherever you want. All you need is a WiFi network and a VoIP account.
