# Accept a parked inbound REGISTER attempt

`POST /sip/registrations/attempts/{id}/accept`

Binds the AOR and replies 200 OK for an inbound REGISTER surfaced via the `sip.registration_attempt` event (by its `attempt_id`). Equivalent to letting the consult timeout elapse, but immediate. An optional `max_expires` caps the granted binding TTL.

## Request body

- RegistrationAcceptRequest
  - `max_expires` integer

## Response `202`

Accept queued

## Other responses

- `400` — Invalid max_expires
- `404` — Registration attempt not found or already decided
