Cloud telephony company Twilio has announced beta support for WebRTC at its conference in San Francisco.

WebRTC is a project supported by Google, Mozilla and Opera and lets you do real time communications, including access to camera and microphone, using a JavaScript API without a plug-in. There is also a W3C Working Group.

WebRTC support will be a feature of the Twilio client:

When Twilio Client apps are used with a WebRTC compatible browser, such as future versions of Google Chrome and Mozilla Firefox, Twilio Client will automatically take advantage of the improved audio performance of the WebRTC technology. If the browser doesn’t support it, Twilio Client will still work and fall back to existing browser technologies.

says Twilio.

Other new APIs announced at the conference include Test Credentials, which lets developers test code against the Twilio API without actually placing calls; Usage for retrieving Twilio usage logs and Usage Triggers which you can use to implement usage caps in order to limit cost.
