WhatsApp has over two billion active users, but for developers building real-time communications applications, it’s long been a walled garden. That’s changing. WhatsApp Business Calling is opening new doors for SIP-based integrations, and the technical landscape around it is evolving fast.
In this episode, Dan Jenkins joins us to break down what combining WhatsApp Business Calling with WebRTC and SIP actually looks like in practice: the use cases, the architecture decisions, and the technical challenges that come with it.
Dan Jenkins is founder and CEO of NimbleApe, Everycast Labs, and the organizer of the CommCon conference series. As always, Dan will bring his expertise in low latency media, video streaming and broadcast technologies to our conversation.
The episode also features Arin Sime and Tsahi Level-Levi’s Monthly WebRTC Industry Chat. This month, they discussed: OpenAI’s Secret WebRTC Architecture: No SFU? No Problem! (based on OpenAI’s recent blog post: How OpenAI delivers low-latency voice AI at scale)
