Integrate Twilio Inbound Calls with Vapi for HVAC Scheduling via Google Calendar API TL;DR Most HVAC shops lose 30% of inbound calls because they can't book appointments in real-time. This setup pipes Twilio inbound calls into a Vapi voice AI agent that extracts appointment details, checks Google Calendar availability, and auto-books slots - no human transfer needed. Stack: Twilio webhooks → Vapi function calling → Google Calendar API. Result: 24/7 scheduling, zero missed leads.
