Twilio has developed a simple way for businesses to integrate WebRTC into their PBX or call center, allowing employees to make voice calls from anywhere using only a browser or mobile application. The Twilio SIP to WebRTC solution enables seamless communication by transcoding calls from the existing PBX system to WebRTC, which is built directly into browsers and provides high-quality voice communications. With this solution, businesses can easily embed a WebRTC client into their web applications and start taking and receiving calls without requiring any additional software or hardware installation.
