WebRTC Weekly Issue #650
Six round trips down to one, MoQ gets an API, and several vendors roll out releases
Two items this week are the same story arriving from opposite ends. OpenAI cut WebRTC call setup from six round trips to one and took the work to the IETF instead of keeping it, and Chrome 151 is already shipping one of those sub-drafts.

How we built a realtime system for responsive voice AI in six months (OpenAI)
OpenAI changed the game in Voice AI. It took the turn detector out of the audio path entirely and let the model decide when to speak. They cut WebRTC call setup from six round trips to one with WARP. Part of the changes made were architectural. This is going to affect all Voice AI vendors and frameworks - commercial and open source. This is going to be interesting to see how it develops.

✍️ This Week on BlogGeek.me
WebRTC won’t fix your call quality. Observability will - WebRTC’s call quality is no better than any other VoIP protocol, and a discovery call reminded me why teams keep expecting otherwise. What separates the ones who fix quality from the ones who keep guessing is whether they can see what is actually happening
