The article introduces a programmable voice solution using Twilio API to implement an escalation loop for incident notifications, allowing monitoring teams to quickly dispatch technicians to fix issues. The solution uses three reusable Twilio Functions: `/start`, `/call/start`, and `/call/webhook`. These functions work together to call numbers in an ordered list until one of them answers or a predetermined number of attempts is reached. The system can be easily deployed on a Twilio project by registering for a free account, purchasing a phone number, and following the provided tutorial.
