Direct contact via WebRTC


Definition "WebRTC"

Web Real-Time Communication is an open standard for real-time communication (VoIP, chat, video telephony) using a web browser on the Internet. It allows voice and video connections to be established between two web browsers without the need to install any additional software beforehand. Data and files can be exchanged in parallel. The use of WebRTC thus significantly improves customer service, as customers can contact your service staff directly. It is therefore ideal for live support.
