Xirsys ICE / STUN / TURN Tester

Fetch Xirsys STUN/TURN from PHP and run browser ICE gather tests. STUN remains enabled so host, srflx, and relay paths are all visible.

API / account settings

Credential Mode Custom credentials are sent to this PHP tester endpoint for the request only and are not saved by this package. API Path Usually https://global.xirsys.net.

Xirsys Channel Maps to /_turn/channel420/Lobby. This can match the webinar room/session path. ICE Transport Policy Use All for webinar-style behavior. Relay-only confirms TURN allocation.

Ready.

Info / webinar integration notes

For the webinar app, use iceTransportPolicy: "all" so the browser can use host and STUN server-reflexive paths first, then TURN relay only if direct connectivity fails.

const ice = await fetch('api.php?action=turn', {
  method: 'POST',
  headers: {'Content-Type': 'application/json'},
  body: JSON.stringify({ channel: room })
}).then(r => r.json());
const pc = new RTCPeerConnection({
  iceServers: ice.v.iceServers,
  iceTransportPolicy: 'all'
});

Error 701 is counted as a STUN warning. If server-reflexive candidates appear, STUN is working even if some STUN URLs/interfaces fail.

Relay classification uses candidate.url when available. Relay candidate ports are usually allocated high ports, so the tester looks at the TURN URL, not the relay port.
