A true local gateway for agentic phone control.
Clawfinger turns a regular Android phone into a voice interface for your AI agents. It consists of two parts: a phone bridge app that handles the calls, and a gateway running on your computer that connects those calls to the LLM of your choice. Your agents can listen, speak, and act — all through real phone calls on a real mobile number.
- Control your agents by calling them. Pick up any phone, dial your Clawfinger number, and talk to your agent directly.
- Let your agents make and receive calls on your behalf. Schedule appointments, return missed calls, handle inquiries — hands-free.
- Trigger any action through conversation. Your agent's existing tool-calling pipeline works during calls, so anything your agent can do, it can now do by voice.
Most voice-AI setups rely on SIP trunks, VoIP providers, or landline integrations. Clawfinger takes a different approach: it uses an actual phone with a regular SIM card. Here's why that matters:
| Traditional (SIP/VoIP) | Clawfinger | |
|---|---|---|
| Setup | Trunk provisioning, DID numbers, codec config | Plug in a phone via USB |
| Cost | Per-minute billing, monthly trunk fees | One flat-rate mobile plan |
| Reputation | Shared IP pools — your number can get flagged because of other users in the same pool | Your own SIM, your own number, your own reputation |
| Reliability | Ooh, NAT traversal, ooh, ooh, ooh | It's a phone call. It just works. |
| IoT/Telecom integration | Specialized hardware, complex configuration | Not needed |
A phone: Any Android phone running Android 14 or newer. We recommend a dedicated spare phone — think of it as giving your agents their own ears and voice (and soon, eyes). Do not use your personal daily phone for this.
Don't have a spare phone? A new or refurbished Google Pixel 7a is a great choice. It doesn't need a Google account, and we actually recommend keeping both Google sign-in and Wi-Fi turned off. Just insert a SIM card and you're ready.
A computer: A Mac, Linux box, or any machine that can run your agents. We've verified everything works on a Mac Mini with 16 GB RAM — including the local LLM, speech recognition, and text-to-speech models that Clawfinger uses. No cloud APIs required.
An agent (optional but recommended): Clawfinger ships with an OpenClaw integration for full local phone call management. You can also connect your own agents via the WebSocket API.
Clawfinger is designed for personal agentic use — one phone, one agent, one number. It is not built for bulk dialing or mass outreach. Spammers use specialized telecom equipment that is orders of magnitude cheaper per channel than a single smartphone. This tool is for people who want their AI agent to have a real phone presence, not for scaling outbound campaigns.
Have an Android phone with Android 14+ available. Tested with Google Pixel 7a and Pixel 10 Pro.
If you need to buy one, a new or refurbished Pixel 7a is the sweet spot — affordable, well-supported, and more than capable. No Google account or internet connection required on the device.
Plug the phone into your computer with a USB-C cable. Make sure USB debugging is enabled in the phone's developer settings.
Give your agent access to these two repositories. Each contains a skill file that your agent can read to guide you through setup automatically:
- Phone bridge app: github.com/Trac-Systems/clawfinger-app
- Voice gateway: github.com/Trac-Systems/clawfinger-gateway
Your agent will pick up the installation instructions and walk you through the process step by step.
