AT&T today announced commercial support for Web Real-Time Communications (WebRTC), a client that will allow browsers to make voice/video calls across the internet without the need for additional plugins. According to AT&T, it will support WebRTC on both desktop and mobile browsers. What's key is that when smartphone owners make a call from their mobile browser, the recipient will see the user's mobile number, not a generic ID tag. Moreover, user's can assign their AT&T mobile number to their laptop browser for caller ID purposes, too. AT&T's new support for WebRTC also comes with APIs for developers. AT&T expects developers to use the APIs to add WebRTC-based voice and video calling services to their apps and web sites over time.
