> End app voice call through the Voice SDK integration. Use with the authentication and customer identity flow described in the app voice guide.

# End 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 `{ "success": true }`. Ending a call disconnects all its participants and settles its call history. Repeated requests are safe while the control token remains valid.

If the request fails, the SDK still stops local audio. Server cleanup handles abandoned calls independently. Invalid, expired, or mismatched control tokens return 401.
