rtpbridgeRTP Media Routing Server

High-performance media bridge in Rust — WebRTC, RTP/SRTP, transcoding, recording, and more.

WebRTC & SIP

Bridge WebRTC (DTLS/ICE/SRTP) and plain RTP/SRTP endpoints in the same session. Auto-detects endpoint type from SDP.

Transcode between PCMU (G.711), G.722, and Opus on the fly. DTMF always passes through untouched.

Record to PCAP with accurate timestamps. Independent voice activity detection for IVR, voicemail, and LLM streaming.

Play WAV, MP3, OGG, FLAC from local files or URLs. Seek, pause, resume, loop. Shared decode across sessions.

JSON control protocol over WebSocket. 1:1 session binding. Orphan timeout with reconnection support.

Graceful shutdown for k8s. Split control/media interfaces. Symmetric RTP for NAT. Resource limits.
