What is WebRTC and why does it need TURN servers in India specifically?

WebRTC enables direct peer-to-peer voice and video communication between devices. On Indian mobile networks, carrier-grade NAT often blocks direct connections, making TURN servers essential. A WebRTC SDKs service provider with TURN servers in India keeps latency low (10–25ms), while overseas servers can add 180–240ms, affecting call quality. This makes domestic TURN infrastructure a key factor when choosing WebRTC SDKs services.
