Recordings and retention

WADial records captured call media as WAV files when audio flows through the call. For each call, WADial can create:

Kind	Contents
`inbound`	Audio received from the peer.
`outbound`	Audio sent through WebSocket streaming or prerecorded playback.
`mixed`	A combined WAV track.

Recordings are retained for 30 days by default unless your account is configured with a different retention period. When a recording artifact is ready, WADial emits call.recording.ready:

{
  "type": "call.recording.ready",
  "sessionId": "019f...",
  "data": {
    "callId": "call-123",
    "recordingId": "019f...",
    "kind": "mixed",
    "contentType": "audio/wav",
    "durationMs": 120000,
    "sizeBytes": 3840044,
    "expiresAt": "2026-07-30T12:00:00.000Z"
  }
}

Recording events carry metadata only. Raw audio is never delivered over SSE or webhooks.
