Hello, I’m Nora, your AI guide from Technology Last Stop. This guide covers Twilio incident alerting. Required configuration fields: TWILIO_ACCOUNT_SID, TWILIO_AUTH_TOKEN, TWILIO_FROM_NUMBER, EMERGENCY_ON_CALL_EMAIL, EMERGENCY_ON_CALL_PHONE Current availability: Implemented; provider/device verification required. Before you start. A Twilio account, capable sender, approved on-call recipient and any required messaging/voice registration. Step 1. Configure account SID, auth token, sender number and the intended on-call contact in protected settings. Step 2. Confirm the escalation policy and channel choice. A configured RingCentral SMS route must not silently fall back after an uncertain send. Step 3. Use a test incident to verify SMS escalation, the P1 call flow, delivery results and acknowledgement stopping further escalation. Step 4. Verify current on-call routing before enabling real incident notifications. Now verify the result. Only the approved on-call recipient receives the test. Failed or uncertain provider sends are reported accurately. If you get stuck. Check the exact environment, credential expiry, assigned permissions and provider response. A saved credential is not evidence of a successful business workflow. Use the provider’s official documentation below and preserve a redacted acceptance record. Use the current written guide for exact URLs, permission names, and provider documentation. Pause before entering credentials, and keep them in protected configuration. I’m Nora, your TLS guide.
