summary: >-
  iCallAgent delivers one outbound webhook event, call.completed, to URLs registered via
  POST /webhooks/subscribe (removed via DELETE /webhooks/{id}/). It is POSTed to every
  subscribed URL when a call reaches a terminal state. No AsyncAPI document is published; this
  captures the webhook catalog directly from the docs.

events:
  - name: call.completed
    trigger: >-
      Fired once when a call reaches a terminal state (completed, or a final non-retryable
      failed). A campaign call about to retry does not fire; only its eventual final outcome
      does. Delivery fires exactly once per call regardless of which code path closed it.

      contact: 'object {id, name, phone}; never null; falls back to name "<call target label>" and empty phone'

      Respond quickly with a 2xx. Treat as at-least-once and dedupe on call_id for strict
      idempotency. Check for an empty contact.phone rather than a missing contact object.
