{"slug": "agent-ring-your-agent-can-call-you", "title": "Agent Ring: Your agent can call you", "summary": "An open-source, self-hosted project called Agent Ring lets AI coding agents place real voice calls to a user's Android phone, ringing even when the device is locked or in Doze, so the user can talk through a decision and hand the transcript back to the agent. Agent Ring routes calls over VoIP from the user's own server with no phone numbers, no Twilio and no per-minute fees, and connects to any MCP-speaking harness including Claude Code, Codex, opencode, OpenClaw and Hermes, with Gemini Live handling the real-time voice conversation. The project is pre-release, Android-only, and has been tested on one device, a Pixel 6 running Android 16.", "body_md": "**Your AI agent can call you.** When it needs a decision, hits a wall or finishes a\nlong job, your phone rings like a real call, even locked and in Doze. A voice AI tells\nyou what's going on, you talk it through, and the agent gets the transcript and carries\non. You can also call your agents back from the app and ask them things by voice.\n\nSelf-hosted and open source. No phone numbers, no Twilio, no per-minute fees: calls go over VoIP from your own server to your own phone.\n\n## agentring-demo.mp4\n\n*Sound on. A real run with Claude Code, a Pixel 6 and the voice AI: a migration fails, Claude Code\ncalls the locked phone, you decide, it carries on. The phone is a screen recording with the call\naudio (the ringtone was added), the terminal is redrawn from Claude Code's output, and only the waits were cut. Silent\nversion: [demo.gif](https://github.com/mutonby/agentring/blob/main/docs/media/demo.gif).*\n\n**Pre-release.** Messages, calls on a locked phone, the voice AI, calling your agent\nfrom the app and the MCP server all work. So far it has been tested on one phone\n(Pixel 6, Android 16). Android only for now.\n\n- **Your agent reaches you.** It can send you a message, wait for your reply or call\nyou (`send_message` ,`get_replies` ,`call` ). On a call, a voice AI explains why the\nagent is calling, answers your questions and hands the transcript back.\n- **You reach your agents.** Tap \"Call agent\" in the app. The voice AI can ask your own\nagents for help mid-call. If one is slow, the call goes on and its answer arrives\nwhen it's ready, or as a message if you've already hung up.\n- **Nothing gets lost.** A missed call turns into a message you can answer from the\nnotification.\n\nThings people use it for: *\"run the migration and call me if anything fails\"*, *\"ask\nme before you deploy\"*, *\"what did CI say?\"* while driving, a daily call with your\nassistant about your inbox.\n\nagentring doesn't care which harness you use: anything that speaks MCP can reach you, and anything you can run as a command can be consulted from a call.\n\n|  | Reaches you | You consult it from a call | \n|---|---|---|\n| Claude Code | MCP | `claude -p` | \n| Codex | MCP | `codex exec` | \n| opencode | MCP | `opencode run` | \n| OpenClaw | MCP | `openclaw agent` | \n| Hermes | MCP | `hermes -z` | \n| n8n, scripts, anything with HTTP | REST API, CLI | any command, or a small script for an HTTP agent | \n\nCopy-paste setup for each: [docs/agents.md](https://github.com/mutonby/agentring/blob/main/docs/agents.md#recipes-by-harness).\n\n```\n your agent ──MCP/CLI──▶ daemon ──WSS (outbound only)──▶ relay ──FCM push──▶ Android app\n     ▲                     │                      (your server)                   │\n     └── agents.yaml ◀── voice AI (Gemini Live) ◀───── LiveKit (call audio) ───────┘\n```\n\n- **relay** (TypeScript): pairing, messages, call state, push, LiveKit tokens. Runs on\nyour server behind Caddy.\n- **LiveKit** : the call audio, self-hosted in the same compose file.\n- **daemon** (Python): the`agentring` CLI, the MCP server and the voice AI. Runs next\nto your agents, behind NAT is fine.\n- **Android app** (Kotlin): QR pairing, the native call screen, messages.\n\nThe voice AI is the voice, your agent is the brain: Gemini Live handles the conversation in real time and hands real work to your agents.\n\nMore: [architecture](https://github.com/mutonby/agentring/blob/main/docs/architecture.md) · [protocol](https://github.com/mutonby/agentring/blob/main/docs/protocol.md) ·\n[voice AI](https://github.com/mutonby/agentring/blob/main/docs/voice.md)\n\nYou need:\n\n- somewhere to run the relay: a Linux server with Docker and a domain name, **or** your own\ncomputer with Docker (the phone on the same Wi-Fi, or anywhere over Tailscale),\n- a free Firebase project, which is what makes a locked phone ring ([docs/firebase.md](https://github.com/mutonby/agentring/blob/main/docs/firebase.md) ),\n- a Gemini API key for the voice AI ([free tier](https://aistudio.google.com/apikey) ),\n- an Android phone.\n\n```\n# 1.

The full\ntutorial, step by step for both options and with a troubleshooting table:\n**[docs/setup.md](https://github.com/mutonby/agentring/blob/main/docs/setup.md)**. If the phone doesn't ring when locked, it's usually the\nvendor's battery saver: [docs/troubleshooting-oem.md](https://github.com/mutonby/agentring/blob/main/docs/troubleshooting-oem.md).\n\nEverything runs on your own servers and accounts. Messages and call metadata are stored on your relay. Push notifications go through your own Firebase project; they are signed, not encrypted, so Google's FCM can read pushed text. Call audio goes through your LiveKit server and, with the voice AI, to Gemini; on Google's free tier, Google may use that data to improve its products.\n\nOver the phone, the voice AI acts on what it hears, so give it only the tools and\nagents you'd trust someone holding your phone with. Details and the threat model:\n[SECURITY.md](https://github.com/mutonby/agentring/blob/main/SECURITY.md).\n\n- Android only (no iOS yet).\n- One user per relay: no accounts.\n- The voice AI uses Gemini Live; other realtime backends plug in through\n[`RealtimeBackend`](https://github.com/mutonby/agentring/blob/main/docs/voice.md) .\n\n```\ncd relay && npm ci && npm test                         # relay\ncd daemon && uv run --extra voice pytest               # daemon (+ e2e against the relay build)\ncd app-android && ./gradlew :core:test :app:assembleDebug\n```\n\nCI builds the APK and runs an end-to-end test on an Android emulator against a real\nrelay.
