"Run the migration and call me if anything fails" is an instruction your agent can finally obey, because Agentring is the self-hosted bridge that lets AI agents ring your phone and talk it through with you. When an agent needs a decision, hits a wall, or finishes a long job, your phone rings even locked and in Doze; a realtime voice AI explains why it is calling, answers your questions, and hands the transcript back so the agent carries on with your decision. You can also call your agents back from the Android app and ask what CI said while driving; the voice AI can consult your other agents mid-call, and a slow answer arrives when ready, or as a message if you have hung up. A missed call turns into a message you can answer from the notification. Anything that speaks MCP can reach you, including Claude Code, Codex, opencode, OpenClaw, and Hermes, and scripts or n8n reach you through the REST API and CLI. Pick your voice: Gemini Live by default, OpenAI Realtime, Grok Voice, Phonic, or your own local speech server with no key at all. The relay and LiveKit run in one Docker Compose behind Caddy, the daemon sits beside your agents and connects outbound only, and FCM push wakes the locked phone. No phone numbers, no Twilio, no per-minute fees. 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.
