AT&T has launched an Enhanced WebRTC API that allows developers to integrate real-time voice and video calling into their web and mobile applications using existing AT&T mobile phone numbers or virtual numbers. This new API provides a complete WebRTC solution with simple APIs, SDK support, and the ability to make and receive calls to and from connected devices. The API is currently in beta status and available for developers to test with no fees.
