  title: Cisco Expressway Zone Health Investigation
  summary: Inspect zone connectivity, active calls, and recent call history together.
  description: >-
    Investigates zone health by reading zone connectivity status, listing active
    calls currently traversing the system, and pulling recent call history for a
    time interval so failed or dropped calls through a degraded zone can be
    correlated. Every step spells out its request inline so the flow can be read
    and executed without opening the underlying OpenAPI description.
