Part 2 dives into the backend that powers the voice agent. I show how Airtable handles leads, call logs, statuses, and follow-ups, while Supabase stores conversation data and agent memory. You’ll see the full data model, webhook routing, syncing logic, and how everything connects back into n8n so your AI agent can qualify, update records, and trigger automations in real time. Perfect for turning a simple caller into a real sales system.
