Callab AI

AI-voice agents for any telephony stack.

Callab AI is an AI voice agent platform purpose-built to plug into the most complex telephony environments - from legacy CUCM and SIP trunk infrastructures to modern cloud contact centers. Rather than requiring greenfield deployments, Callab AI integrates natively with existing PBX systems, IVR flows, and carrier-grade SIP endpoints, fitting seamlessly within the regulatory and technical constraints of enterprise telecom stacks.
