This is the course that turns you from an AI tourist into an AI builder. You'll build a fully functional AI voice agent that answers phone calls, qualifies leads, books appointments, and sends follow-up texts — using OpenAI Realtime, Twilio, and Node.js. By the end, you'll have a live agent handling calls on a real phone number.

Connect OpenAI Realtime API to Twilio phone numbers
Implement tool calling for calendar booking, CRM, and SMS
Deploy to cloud infrastructure for 24/7 uptime
