Callab AI, built by Clusterlabs, is a cloud-based voice AI platform that connects directly to legacy on-premises PBX/SBC telephony (Cisco UCM, Mitel, FreeSWITCH) via SIP trunk integration, routing calls to AI voice agents with no rip-and-replace migration. The platform automates up to 70% of inbound and outbound call volume across support, sales, and scheduling, with no-code agent building, live human supervision and takeover, semantic knowledge bases, post-call transcription and sentiment analysis, CRM data extraction, and batch outbound campaigns. Callab AI exposes a REST API at docs.callab.ai for programmatic control of agents and calls. A Y Combinator Spring 2026 company founded in 2024, it serves hospitality, logistics, retail, and property management across three continents.
