      summary: Release Phone Number
      description: |-
        Release a number back to the provider's inventory and stop its daily
        billing. This is irreversible: anyone — including other platforms — can
        buy the number afterwards, so callers who saved it may reach a stranger.
        The number disappears from this API immediately.
