About

fonio is an AI phone assistant that answers calls around the clock and handles conversations like a human employee. It can receive calls, understand each caller’s request, answer common questions, collect structured information, forward urgent or specialized inquiries, schedule appointments, and send transcripts or callback notes when staff are unavailable. Businesses can define the assistant’s voice, language, welcome message, in-call behavior, escalation rules, and post-call workflows without coding. fonio can handle multiple calls at once, helping teams avoid missed calls and long hold times during busy periods. Its multilingual assistant supports more than 35 languages, automatically recognizes the caller’s language, responds appropriately, and can switch languages during a conversation. It connects with calendar tools, CRMs, databases, and internal systems through native integrations and APIs, allowing it to check availability, retrieve information, write data back, etc.
