In this talk, we will share the newest improvements to MatrixRTC. We'll focus on how the security and encryption architecture has evolved to provide robust, private communications for Matrix users. Additionally, we will show how to integrate Element Call into clients using the Rust or JS-SDK in a matter of minutes. Whether you're building a custom Matrix client or want to know what makes MatrixRTC such a great solution for secure communication, you'll walk away with practical knowledge to bring encrypted calling capabilities to your users and an in-depth understanding about the key distribution for real- time (MatrixRTC) sessions. In this talk, we'll explore the evolving landscape of MatrixRTC, the real-time communication layer of the Matrix protocol, and highlight key advancements. This year we saw a lot of advancements for MatrixRTC. To make it thorugh the spec review process we gathered feedback and added a couple of our own topics that we really wanted to improve. The changes might seem very small but have a very big impact in how good it fits into the matrix eco system. To name one of the highlights: A matrixRTC session can now be dirstirbuted over multiple SFU servers! On top of that a new matrix primitive will be introduced that greatly helps MatrixRTC and is useful in other parts of the ecosystem. With the spec proposals being as polished as never before and the first reviews from SCT members, there is no better time to accelerate the adoption of MatrixRTC-based calls. With Element Call, we went the extra mile to make this adoption as easy as possible. Element Call, being a widget, is available to the broader ecosystem and can be used as a shortcut to make clients compatible with MatrixRTC calls without much development effort. We would like to show how easy it is to implement Element Call into any JS-SDK or Rust SDK backed client (any client supporting the widget API). At the end of the talk, we will have a live demonstration of a call with a client that did not previously support MatrixRTC-based VoIP.
