# Put a SIP call on hold (asynchronous)

`POST /legs/{id}/hold`

Queues a re-INVITE with `sendonly` SDP direction. The HTTP call returns 202 as soon as the leg is validated; the re-INVITE is sent in the background and success surfaces as `leg.hold`. Failures surface as `leg.command_failed` with `command="hold"`. The RTP timeout is paused while held, and a 2-hour auto-hangup timer starts.

## Response `202`

Hold queued

## Other responses

- `400` — Not a SIP leg
- `404` — Leg not found
- `409` — Hold not supported for this leg type (e.g. WhatsApp)
