For those like me who didn't know what Cloudflare Calls are, and had trouble parsing the headline

FTA:

"Cloudflare Calls lets developers build real-time audio/video apps using WebRTC, and it abstracts away the complexity by turning the Cloudflare network into a singular SFU. In this post, we dig into how we make this possible.

...

Selective Forwarding Units (SFUs) play pivotal roles in scaling WebRTC applications. An SFU functions by receiving multiple media or data flows from participants and deciding which streams should be forwarded to other participants, thus acting as a media stream routing hub. This mechanism significantly reduces bandwidth requirements and improves scalability by managing stream distribution based on network conditions and participant needs."
