About the startup
CallNode gives your AI agent a phone number. Point it at any webhook or WebSocket — it handles voice, SMS, and MMS. Reply with text, CallNode speaks it. No SDKs, no telephony stack, no carrier contracts. Built for developers shipping voice AI: HMAC signing, test mode, OpenAPI spec, and pay-as-you-go from $0.02/min.
