Real-Time Communication (RTC) is a new communication standard based on WebRTC that allows users to exchange audio and video content in real-time directly within their web browsers. WebRTC was released as an open source project by Google in 2011 and has since been standardized by the W3C and IETF to integrate real-time communication capabilities into websites and applications using HTML5 and JavaScript. RTC functions include voice and video calling, messaging, conferencing, and connections to traditional telephony networks through SIP gateways.
