Description
Callab AI, backed by Y Combinator, provides AI voice agents that replace legacy IVR menus with agents that listen, understand, and resolve. It handles support, sales, and scheduling on a business's existing phone system, working with an existing PBX, SBC, and contact center infrastructure out of the box, with no migration or infrastructure changes needed.
A distinguishing feature is live human supervision on every call: supervisors see real-time transcripts, sentiment scores, and AI confidence levels on a dashboard, and can take over any conversation with one click, joining mid-sentence without the caller noticing. Agents can be built and configured in minutes with no code, and the platform provides full observability into every call, decision, and outcome.
Key features include a knowledge base that indexes uploaded manuals, policies, and wikis for reference during live calls, automatic post-call analysis with recording, transcription, and sentiment tagging, context-aware call transfer that carries full conversation history, automatic CRM updates that map names, budgets, intent, and next steps to CRM fields, and batch calling that launches hundreds of personalized calls at once. Callab connects to a PBX via SIP and can move from a discovery call to full deployment in days. It supports Arabic dialects, with pricing from $240 per month for 2,000 minutes.
