What is a WebRTC webphone and how does it work?
WebRTC (Web Real-Time Communication) is an open-source technology that enables voice and video communication directly inside web browsers — no downloads or plugins required. Bit Dialer uses WebRTC to let your website visitors make and receive HD VoIP calls with a single click. The call audio travels over an encrypted peer-to-peer connection through Bitcall's global low-latency edge network, delivering crystal-clear voice quality on Chrome, Firefox, Safari, and Edge.
