About LiveKit

LiveKit is open-source real-time voice/video infrastructure used to build voice agents and live experiences — a WebRTC SFU, telephony (SIP), recording/egress, and the LiveKit Agents framework for STT→LLM→TTS pipelines, available as LiveKit Cloud and self-hosted.

#	Input	Expected behavior	Check
01	Participant on a corporate network with strict UDP egress fails to establish direct UDP to the LiveKit SFU. WebRTC stays in 'checking' for 30 seconds.	LiveKit Cloud advertises TURN/TCP and TURN/TLS fallback in ICE candidates. Client should iterate candidates and complete connectivity check via TURN/TLS 443. Operator should verify client SDK is not configured to filter out relay candidates. Self-hosted deployments must run their own TURN server.	Pass / FailAi Platformcritical
02	Operator wants AV1 video where supported, fall back to H.264. Publisher SDK negotiates codecs per peer connection.	Set publication video codec preference (AV1 first, then H.264). SFU forwards only what subscribers can decode; subscribers without AV1 receive H.264. Verify both sides report the same codec via getStats. Do not force AV1 with no fallback — Safari clients will fail.	Pass / FailAi Platformhigh
03	EU users join a room hosted on LiveKit Cloud with project region=us-east. Voice latency is high.	LiveKit Cloud is a global edge mesh — clients connect to the nearest edge, which forwards via the mesh to the room's home region. Specific p50/p95 RTT envelopes are [REQUIRES-VERIFICATION] and depend on the user-edge distance. For lowest latency, pin room creation to a region close to the majority …	Pass / FailAi Platformmedium
