ANECDOTE

ZipCall's Origin

  • Ian Ramzy built ZipCall because existing video call solutions were too complex.
  • He wanted a simple, browser-based solution, especially for his grandmother.
INSIGHT

Peer-to-Peer Advantage

  • Traditional video call solutions rely on expensive central servers (SFU/MCU).
  • ZipCall uses WebRTC for peer-to-peer connection, drastically reducing server costs.
INSIGHT

STUN and TURN Servers

  • WebRTC uses STUN and TURN servers for network traversal and peer connection.
  • STUN helps establish direct connections, while TURN relays data when direct connections fail.
