Agentring
Agentring is an open-source self-hosted agent tool that lets AI agents call phones over VoIP.
Agentring is an open-source, self-hosted product that lets AI agents call users over VoIP when they need a decision, hit a wall, or finish a job. A voice AI, powered by Gemini Live, explains the situation on a call, answers questions, and returns transcripts to the agent. Users can also call agents back from the Android app to ask questions by voice. It uses LiveKit for audio and a Python daemon alongside a TypeScript relay server. The system supports MCP-compatible agents like Claude Code, Codex, opencode, OpenClaw, and Hermes, as well as HTTP-based scripts and tools.
