VoIP and WebRTC in Real World Apps
VoIP and WebRTC in Real World Apps VoIP and WebRTC power real-time voice and video in many real world apps. VoIP is a broad term for internet calls, often built with SIP and RTP. WebRTC focuses on browser and mobile integration, with built-in media handling and NAT traversal. Together they let products add calls, chats, and collaboration without heavy desktop software. Core building blocks include signaling to start and end calls, media paths (peer-to-peer, SFU, or MCU), and NAT traversal with STUN and TURN. Codecs and encryption (SRTP and TLS) protect audio and video. Network quality controls help manage bandwidth and adaptive bitrate. A small app can work with a direct connection, while a larger one may use an SFU to serve many participants. ...
