  title: Cisco Expressway Status API
  description: >-
    RESTful API for retrieving status information, alarms, call history,
    licensing status, upgrade progress, registration details, and system
    health metrics from Cisco Expressway. Status endpoints follow the
    pattern /api/status/common/ for items common between Expressway-E and
    Expressway-C. The API uses JSON Schema version 4 for response schemas
    and requires HTTPS with HTTP Basic Authentication using Expressway
    administrator credentials.
