Missed Call SMS Bot — AI generates a warm reply, Twilio sends it (n8n template)
Built this for appointment-based businesses (clinics, salons, auto shops) that lose leads when they miss a call.
How it works:
1. Phone system sends a missed-call webhook with caller number
2. AI generates a friendly SMS: “Hi there, sorry we missed your call. Reply to book an appointment!”
3. Twilio delivers it — all under 160 characters
Why this exists:
I noticed small businesses treat missed calls as lost opportunities. Most can’t afford a receptionist 24/7, but they can afford a $14 template + Twilio credits (pennies per SMS).
Tech stack:
- Webhook trigger (POST /missed-call)
- Format Data node to normalize caller info
- GPT-4o-mini for SMS generation
- Twilio for delivery
