The Missed Call Callback Bot is a voice automation built for home services businesses using Retell AI, n8n, and GoHighLevel.
It is designed to call back missed callers quickly, ideally within 60 seconds, so the business has a better chance of winning the job before the caller contacts someone else. The bot speaks in the Mike home services persona, confirms what the caller needs help with, collects any missing details, offers available service times, and helps move the caller toward a booking.
Retell handles the outbound callback conversation, n8n manages the call trigger and outcome routing, and GoHighLevel stores the contact, appointment, tags, and follow-up actions.
This bot is a strong fit for plumbing, electrical, HVAC, gas, and general home service businesses where speed to response matters and missed calls often mean lost revenue.
