  title: Twilio Place a Call and Record It
  summary: Start an outbound call, begin recording the in-progress call, then fetch the recording resource.
  description: >-
    A voice compliance and quality pattern. The workflow initiates an outbound
    call, captures the call SID, starts a recording on that live call, and then
    fetches the recording resource to confirm it was created and to read its
    status. Every step spells out its request inline so the flow can be read and
    executed without opening the underlying OpenAPI description.
