# Get web call

See [Voice SDK integration](/phone/voice-sdk) for authentication, platform packages, routing, and preview availability.

Use `Authorization: Bearer <controlToken>` for this exact call. Returns HTTP 200 with `state`: `waiting`, `queued`, `connected`, or `ended`. The SDK polls this endpoint automatically.

`connected` requires an observed ready support participant. A queued offer or acceptance without a joined participant is not reported as connected. Invalid, expired, or mismatched control tokens return 401.
