Open source project for VOIP calls to a bot

Community

Hello everyone,
Are there any VOIP enthusiasts or experts here? If so, we might have something to discuss.
I’m talking about the AI Voice Connector from OpenSIPS – the team has given the community a working bridge between VOIP and OpenAI Realtime API.
Now, it’s fully possible to call your bot using any SIP-compatible PBX.
Personally, I went a step further and tried to implement function handling in the workflow builder dify.ai (in theory, integration with any other workflow builder is possible in the future). I also made a simple web interface using Django (Python) for creating and managing voice VOIP bots (this is exten.bot)

I’m very happy with this capability, as I’ve worked with Asterisk for over 10 years and always looked with a bit of envy at services offering voice bots.

I have been doing a large project connecting sip phone lines to the real time api. I started with the demo projects and built up from there. I’m using node.js for the proxy and .net for the platform.
