CallCore installs as a server inside a Virtual Machine (VM). This keeps it stable, isolated, and easy to manage.
CallCore runs as a server appliance inside a Virtual Machine (VM). A VM lets you run a server on your computer while keeping it separated from everything else.
We recommend Oracle VirtualBox (free, easy, and works on Windows/macOS/Linux).
