   WebRTC helped me to launch my startup after 2 years of waiting.▲42

   Hi All ,I been working on my idea , A Voice CRM solution for 2 years.When I started brainstorming the idea the only option I have to receive phone calls thru browser was a flash widget or use 3rd party providers like Twilio or Phono . Thanks to WebRTC we now integrated our VoIP services to receive and make calls directly thru browser .Please have a look and give us your feedback .Thanks Voz.io Team .

   WebRTC Data Channels Example▲91

   https://github.com/TomasHubelbauer/webrtc-data-channel-demo Hi! I made this GitHub repo to try and show WebRTC data channels and the connection establishment flow in a different way from what I was able to find online. My aim with this repository is to make WebRTC data channels accessible to any web developer by showcasing offerer and answerer separately for total novices (makes it much clearer what's going on on each end of the connection) as well as combined approach where a peer can be both offerer and answerer. I use postMessage instead of a real signalling channel,…

    WebRTC Nuts and Bolts, A holistic way of understanding how WebRTC runs▲124

    Hi HN! I’m so excited to show my first open-source project and first post here. I initially started this project to learn Go language, it is an experimental project. The main goal is to track the adventure of a WebRTC stream from start to finish, by debugging the project or tracking the output at console. By trying out this project, you will deep dive into the steps which are taken while starting up a WebRTC session, and more. It consists of a web UI (TypeScript) and a server back-end (Golang) projects. They can run on Docker containers, in development mode or production mode, you can find…

    Open source framework OpenAI uses for Advanced Voice▲266

    Hey HN, we've been working with OpenAI for the past few months on the new Realtime API. The goal is to give everyone access to the same stack that underpins Advanced Voice in the ChatGPT app. Under the hood it works like this: - A user's speech is captured by a LiveKit client SDK in the ChatGPT app - Their speech is streamed using WebRTC to OpenAI’s voice agent - The agent relays the speech prompt over websocket to GPT-4o - GPT-4o runs inference and streams speech packets (over websocket) back to the agent - The agent relays generated speech using WebRTC back to the user’s device The…
