agentring
agentring is a self-hosted, Apache-2.0 project that lets AI agents like Claude Code, Codex, OpenCode and OpenClaw message you or ring your Android phone over VoIP, where a Gemini Live voice AI explains the situation and hands the transcript back to the agent.
Why it matters
For developers who leave agents running long jobs and step away. Instead of checking a terminal, the agent can ring your phone, even when it's locked, when it needs a decision or finishes, with no phone numbers, Twilio or per-minute fees.
Highlights
- Agents get send_message, get_replies and call tools over MCP; anything else can use the REST API or CLI.
- Calls ring like a real call on a locked phone; a Gemini Live voice AI explains why the agent is calling, answers questions and returns the transcript.
- You can call your agents from the app, and the voice AI can consult them mid-call through commands like claude -p, codex exec or opencode run.
- Missed calls turn into messages you can answer from the notification.
- Self-hosted: a TypeScript relay and LiveKit in Docker on your server or computer, a Python daemon next to your agents, and a Kotlin Android app paired by QR code.
Taken from the project's own README, docs or launch page. Claims about speed or accuracy are the maker's unless stated otherwise.
Worth knowing: Pre-release, tested on one phone (Pixel 6, Android 16). Push text passes through Google's FCM unencrypted, call audio goes to Gemini (and on Google's free tier may be used to improve its products), and the voice AI acts on what it hears, so limit the tools it can reach.
