Call Response Latency
The Challenge
Peak hours generated over 150 customer calls per day for reservations and takeout orders. Manual coordination resulted in 22% missed calls, table double-bookings, and high front-desk staff fatigue.
Our Engineering Solution
Engineered a low-latency conversational Voice AI assistant using Vapi, integrated with n8n workflow pipelines, and connected directly to the restaurant's Square POS and Twilio. The system handles bookings, takes custom order modifications, checks live table availability in a PostgreSQL database to prevent double-bookings, and sends booking SMS details via Twilio.
Key Implementation Details:
- Defined conversational pathways, menu catalog schemas, and logic forks. 2. Created n8n orchestrator pipelines to connect Vapi voice sessions with local PostgreSQL and Square POS APIs. 3. Configured Twilio SMS hooks to route automatic booking details and confirmations to clients.
