- ReputationNumberOwnershipWrapped

    - `source` 'telnyx' | 'external': Where the phone number is hosted. `telnyx`: in your Telnyx inventory. `external`: a number you own that is hosted with another provider.
    - `ownership_status` 'verified' | 'flagged' | 'pending_confirmation' | 'removed': Result of ongoing ownership checks. `verified`: the number is with the carrier on record. `pending_confirmation`: the number's carrier changed, or a periodic ownership re-verification is due; confirm you still own it before `confirm_by`. `flagged`: a periodic re-verification went unanswered; the number stays monitored and is not removed, but confirm ownership (`POST .../ownership_confirm`) to return it to `verified`. `removed`: the number is no longer monitored; returned by `POST .../ownership_confirm` with `still_own: false`, and when listing numbers with `filter[ownership_status]=removed`.

      - `event_type` string: `added`, `check`, `flag`, `confirm` or `removed`.
