WebRTC Test

Verifies that this workstation can complete a WebRTC connection. If this passes, Zoom, Teams, Slack Huddles, Google Meet, and similar apps should be able to connect.

Read the WebRTC Test guide for help reading the verdict or fixing each failure mode.

Privacy: This test creates two RTCPeerConnections inside this browser tab and queries public STUN endpoints to discover ICE candidates. It does NOT request camera or microphone access. Your local IP and public IP are visible to this page (that is the point of step 2) but are not transmitted anywhere. The call-quality step (step 4) times a short burst of requests to edge.desktest.net (a Cloudflare Worker that stores nothing); no audio, video, or IP address is sent. View source to verify.

Configuration

Driver: RTCPeerConnection + STUN

Takes about 15 seconds. The test connects to public STUN servers and times a short burst of requests to the desktest edge (edge.desktest.net) for a call-quality reading; no audio or video is captured.

Status Check Step

Pending

WebRTC APIs are available

Feature-detects RTCPeerConnection, getUserMedia, getDisplayMedia, and codec support.

End-to-end peer connection negotiates

Connects two in-page RTCPeerConnections and round-trips a data channel message.

Round-trip latency and jitter are call-grade

Times a short burst of requests to the desktest edge to estimate call quality (latency and jitter).
