AI Native Call Center is a self-hosted call center where a voice model answers the phone first and people step in only when the conversation actually needs one. Calls land on FreeSWITCH and connect straight to a speech-to-speech provider, and a flow engine steers each call through phases that carry instructions and the tools the model may use, with transitions firing on tool results. When a person is required, the call transfers into a real queue and the agent's browser screen has already popped with the caller's details and the bot-phase transcript ready to read. Agents handle presence, call control, and callbacks from the web interface, and a companion browser extension holds their SIP registration and audio. Supervisors watch a live wallboard with the queue view and the agent roster. Persona, rules, and voice are published and versioned together, and flows are plain documents you can author and validate before loading. Every conversation, bot-answered, handed over, and finished by an agent, lands in a single call record holding one transcript and one recording stored on a filesystem or an S3-compatible bucket. The interface and the bot work in English and Chinese, with provider choices for different regions including an option to run your own realtime gateway. Running on a dedicated VPS on RepoCloud with guaranteed CPU, RAM, and SSD, full root SSH access, and a browser serial console. Apache-2.0 licensed.
