A multi-channel virtual front desk

A multi-channel virtual front desk for a small dental clinic, built in n8n as a single LangChain toolsAgent (the Dental Support Agent) wired to nine typed tools. The agent answers FAQs, books and cancels 30-minute appointments inside the clinic's Africa/Lagos business window, captures CRM data, escalates billing disputes and dental emergencies to humans on Slack, and replies in voice when a patient sends a Telegram voice note all through one shared Postgres-backed conversation memory. The most impressive technical move is the single agent that owns the entire operation and reaches into the rest of the system through another workflow dispatcher that re-enters the workflow eight ways via a switch node.
