Been building on LiveKit for ~1 year. We're now doing 100K+ calls/day across enterprise clients and just opened the platform for public self-serve signups. What we built: • Voice AI agents with native telephony in 70+ countries • SIP import with no restrictions (including UAE, India where most providers block it) • 30 min free credits to test end-to-end Whole stack runs on LiveKit. Happy to share what we learned scaling real-time voice infra, SIP patterns, and handling enterprise call volumes if useful to anyone here. Try it out: https://zudu.ai
