What is WebRTC?
2 min read · Bolcho
A browser technology for real-time audio and video, used to run voice-AI calls directly on a website without any phone number.
WebRTC explained
WebRTC lets a website or app carry a live voice conversation peer-to-peer, in the browser. Voice-AI platforms use it for in-browser demos and web calls, and pair it with SIP for phone calls.
Bolcho uses LiveKit for its real-time media layer, which supports both WebRTC web calls and SIP phone calls.
Why it matters for voice AI in India
Understanding webrtc helps you build voice agents that actually work for Indian callers, genuine languages, low latency, and near-cost pricing. Bolcho is built around exactly these fundamentals.
