MCUs are time-tested approaches to setting up conferences via bridges. Conference bridges add centralized call and media features like mixing, quality control, secure PIN-based access, and more. They are also ideal for connecting mixed streams with media pipelines for recording, broadcasting or plugging into machine learning models. Altanai shows us how to configure FreeSWITCH as a WebRTC Multipart conferencing server using a video mixer and conference bridge.
SFU has become a popular WebRTC topology for connecting through a centralized server to support a medium-sized VoIP conference. Altanai reviews the differences between Mesh, MCU and SFU for handling media streams and demonstrates Asterisk’s SFU configuration for WebRTC endpoints.
STUN and TURN are two types of WebRTC signaling servers that can be used to create a real-time, peer-to-peer connection. In this post we will explain why we need them, when we need them, why one is beneficial to the other, and how you can get around the problem altogether using a CPaaS.
