Insert the USB into your bare-metal server (or VM) and boot from it. You will be greeted with the Vicibox installer screen.
Do not just copy the file. Use tools like Rufus (Windows), BalenaEtcher (Mac/Linux), or dd (Linux) to create a bootable drive.
Think of it as a "turnkey appliance." You burn the ISO to a USB drive, boot your server, answer a few simple questions (like your IP address and timezone), and within 15 minutes, you have a fully functional dialer. Warning: Do not download Vicidial ISOs from random torrent sites or third-party file lockers. These are often outdated, filled with malware, or missing critical security patches.
