Modern Call Signalling for WebRTC

What if WebRTC setup could be more than just ad hoc HTTP, WebSockets or SIP? Discover how Matrix designed a modern VoIP signalling open protocol specifically for WebRTC. The result? End-to-end encrypted voice and video calling in a decentralised, open federated network of 30M+ users.

Distributing SFUs using virtual networks

Virtual networks over the public internet are commonly used to improve routing. Learn how to leverage virtual networks to build a globally distributed SFU network that can handle a high number of callers per conference.


Media quality

Reducing latency on the public internet could be unpredictable and when you add AI and ML to the mix, it can be even more daunting. Learn tips on how to easily improve your public internet latency while also adding AI and ML to your video calls.

Making WebRTC on the Mobile Web Wonderful

WebRTC and mobile browsers have matured to a point that it is now possible to build fully functional, web-based calling applications on mobile – no native app deployments required.

Optimized real time audio is not just for work meetings

The pandemic has pushed real time communications into new domains such as live concerts, music lessons, and virtual environments. Optimizing audio in these settings is very different from typical voice quality tuning for office meetings. In this session, Dolby will share learning from its research on improving audio in these exciting new real time communications use cases.
