" Since Skype emerged in late 2003, Voice over the Internet (VoiP) technology hasn't had many improvements. The whole field of calling other people through the internet has been almost totally dominated by Skype despite the 2013 introduction of the open-source WebRTC (Web-based, Real-Time-Calling) protocol released by the World Wide Web Consortium (W3C), which has been built into Chrome, Firefox and Opera browsers already. "
You do not need to download or install any software, like Skype.
“WebRTC is an open source project that aims to add real time communication capabilities to web browsers. ”
