About Callr
CALLR is the voice infrastructure AI runs on. We give businesses the tools to build, automate, and scale voice conversations — from REST APIs and low-code workflows to fully autonomous AI Voice Agents with native SIP integration. As a registered carrier operating across 220+ countries, we own our network end-to-end: direct fiber interconnections, our own number ranges, and multiple data centers — so you get enterprise-grade reliability without the enterprise complexity. Whether you're a marketplace, a SaaS platform, or an AI-first product team, CALLR integrates into your stack in hours, not weeks.
