delivery:
  signature: Signed webhooks are enabled by default for Voice, Messages and Dispatch APIs. The incoming webhook includes a JWT token in the Authorization
    header signed with your signature secret.
  retries: If the webhook endpoint returns a non‑2xx status code, Vonage will retry the request once. For the Voice API event webhook, a retry
    is also attempted when the response status is 429, 502, 503, or 504.
