How It Works


Call-Box app uses direct connections only. You can't call if it's impossible to establish p2p connection.


There's no backend of it at all. Call-Box app uses public STUN servers to analys network connection.


There're no accounts in the Call-Box. The app generates a link using current network connection data every launch.


To make a call just share generated link using any channel. Nobody knows even about a fact you call.
