About this product
Run the toolkit on your own computer or server and choose providers for speech recognition, language models, voice synthesis and telephony. The project documents a local speech and model stack using Whisper, Ollama and Kokoro.
Key Features
- Use Vapi-compatible assistant configuration and API calls, and test a voice assistant in a browser.
- Connect a telephony provider or SIP trunk and inspect call records and provider cost breakdowns.
Requirements
- Version 0.1.6 on PyPI requires Python 3.11 or later. Real phone calls require a configured telephony provider or SIP trunk.
Limitations and considerations
- The maintainer reports real-call validation for Twilio. Other carrier integrations have primarily been tested against simulations.

Pricing notes
- OpenRing charges no per-minute platform surcharge. Telephony, model and speech providers and hosting may still incur costs.
