LobbyStack

LobbyStack is an open-source AI receptionist that answers missed calls, qualifies leads, and books appointments around the clock. It steps in when your team is busy, after hours, or on any call you choose. The system captures caller details, service needs, and next steps so your team can follow up with full context. You can set it to answer every call or only when no one picks up.

Setting up LobbyStack takes minutes. You connect a phone number — either a new local one or forward your existing business number. Then you import your website, PDFs, service lists, FAQs, and policies so the AI answers with the same knowledge your team uses. You decide when it should book appointments, take a message, or transfer an urgent call to a human. Every call gets a recording, transcript, summary, and booking details stored in one dashboard. The AI receptionist can check your calendar, offer time slots, and send confirmations automatically.

LobbyStack works best for small businesses, service professionals, and teams that rely on inbound calls for leads and bookings. It handles routine questions, intake, and appointment scheduling so your team can focus on complex work. Because it's open-source and self-hostable, you keep full control of customer data. The free tier includes 30 voice minutes per month, with paid plans starting at $30/month for higher volume.
