AI Voice Appointment Agent
AI voice agent that answers the phone, talks naturally and books appointments by voice.
Overview
AI voice agent that answers the phone, talks naturally and books appointments by voice. I built an AI voice agent (Vapi + Twilio) that answers calls in a natural voice, understands what the caller wants, checks availability and books the appointment on the spot — then logs everything through n8n and texts a confirmation. It never sleeps and never puts a caller on hold. Built with Vapi, Twilio, OpenAI, n8n, this ai automation project was delivered for a client in USA and designed for reliability, a clean user experience and long-term maintainability — so it keeps delivering value well after launch.
The challenge
A local business missed calls after hours and during busy periods — every missed call was a lost booking, and voicemail rarely got a callback.
