CallNode (callnode.io, operated by Mobiiworx Inc.) provides phone numbers as infrastructure for voice AI: it connects phone calls and texts to AI agents and automation workflows such as CrewAI, LiveKit, n8n, Flowise or any native webhook. Developers provision a number, point it at a webhook or WebSocket, and handle real voice, SMS and MMS traffic across US and Canada coverage with pay-as-you-go pricing, plus SIP trunking, email, fax, test mode, an MCP integration for Claude and ChatGPT, and a wholesale offering for service providers.
