30 Broadcasters, Unlimited Audio
Up to 30 active speakers can transmit camera feeds and screen shares concurrently, while hundreds of thousands listen via Opus audio.
Instant Screen Sharing
Share your smartphone display or desktop application window with full system audio passthrough for presentations and webinars.
Neural Noise Suppression
Real-time audio filters dynamically isolate human vocals and cancel out background hums, typing clatter, and acoustic room echo.
hub WebRTC Selective Forwarding Unit (SFU) Architecture
Traditional peer-to-peer (P2P) video calls fail when more than 4 participants join because every device must encode and upload separate streams to each peer (N × (N - 1) streams). This saturates mobile uplinks and overheats processors.
Telegram solves massive group calls with an enterprise-grade Selective Forwarding Unit (SFU). Each speaker uploads only one high-definition stream to Telegram's edge media server. The SFU dynamically transcodes and routes tailored lower-bitrate layers to mobile viewers while delivering pristine 1080p to desktop participants on fiber connections.
