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.

If you’re ready to build a WebRTC based live video application, the most important architectural decision you need to make is what media server to use. But which media server should you choose? There are so many options, and they range from tightly controlled commercial APIs to open source projects. Arin covers the five main decision points on which you should base your decision.

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.

For use cases like telehealth where security and privacy are paramount, WebRTC developers use ICE servers to find their way through restrictive firewalls. In this blog post, we will review the signaling process, STUN and TURN servers, and share some tips on how to alleviate ICE issues that can be caused by certain network restrictions.
