Give Your OpenClaw Agent a Phone: Open Source Plugin for Voice Calls
A Reddit user, tristanbrotherton, open-sourced a plugin that gives OpenClaw the ability to make phone calls. The post on r/openclaw notes that several SaaS versions charging $20/mo exist, so the author decided to release their own implementation as free and open source.
What It Does
The plugin enables OpenClaw to initiate real-time voice calls. The code is available on GitHub at https://github.com/TristanBrotherton/openclaw-voice-call-realtime. It's a self-hosted alternative to subscription-based services that offer similar functionality for a monthly fee.
Key Details
- Open source (no SaaS fees)
- Real-time voice call capability for OpenClaw

Who It's For
