How to configure it, confirm it works, and why it should stay the last resort.Mon, 28 Sep 2026 23:00:00 GMTturniceWebRTC E2EE with SFrame: what your SFU can still readhttps://webrtc.wiki/articles/what-your-sfu-can-still-read/https://webrtc.wiki/articles/what-your-sfu-can-still-read/SFrame hides WebRTC media from the SFU, not the metadata. Your server still sees who spoke, when and how loudly, from the audio level header extension.Sun, 27 Sep 2026 23:00:00 GMTdtlsWebRTC bitrate stuck low? maxBitrate is only a ceilinghttps://webrtc.wiki/articles/max-bitrate-is-a-ceiling/https://webrtc.wiki/articles/max-bitrate-is-a-ceiling/You set maxBitrate to 2.5 Mbps and WebRTC sends 700 kbps. The congestion controller picks the rate.
