Appointment Booking System
An intelligent voice-based appointment booking system that handles incoming calls, understands natural language requests, and automatically schedules appointments in real-time.
The Problem
The client was losing potential customers due to missed calls during busy hours and after business hours. Manual appointment scheduling was time-consuming and error-prone, leading to double bookings and customer frustration.
The Solution
We built an AI-powered voice assistant using n8n workflows integrated with Twilio Voice API for call handling, OpenAI for natural language understanding, and Google Calendar API for real-time availability checking and booking. The system handles unlimited concurrent calls 24/7.
