ChatGPT answers calls on a normal SIM with a $6 ESP32
Original: Show HN: ChatGPT answers calls on a normal SIM. No Twilio, just a $6 ESP32
A hobbyist project lets ChatGPT pick up phone calls made to a regular SIM card, using a $6 ESP32 microcontroller and no Twilio or other telephony service in between. The build routes incoming calls to the AI, so callers effectively speak with a chatbot on an ordinary mobile number. Hacker News readers are sharing and discussing the hack, drawn to how cheaply it sidesteps conventional telephony infrastructure.
Why now: A cheap DIY hack replacing paid telephony services with a $6 chip is a novel, technically impressive achievement
