What is AI Native Call Center?
AI Native Call Center is a self-hosted call center platform where AI voice agents answer every incoming call by default. The AI leg runs as a SIP endpoint inside the Go application, bridged by FreeSWITCH, with audio passed directly to realtime speech-to-speech providers (OpenAI, Grok, Qwen, Doubao, or a compatible gateway). A flow engine steers conversations through phases and tools, and transfers to human agents in mod_callcenter queues when needed — the agent's browser screen pops with the transcript before the phone rings. Agents use a companion Chrome extension (web-sip-phone) for audio. Every call produces a single CDR with transcript and recording, stored on the filesystem or any S3-compatible backend. The stack runs as three containers (PostgreSQL 18, FreeSWITCH 1.11, and the Go application with embedded SPA) via Docker Compose, with a one-line installer for Linux and macOS. Minimum 4 CPUs and 4 GiB RAM. Licensed Apache-2.0.
