Hardware, not slots
The plan sets the price, not the headcount
What you rent from us is hardware, and billing follows the plan rather than the number of people connected. The slot ceiling is set by TeamSpeak's own licence: unlicensed use means one virtual server and 32 slots, and beyond that you take a licence from TeamSpeak Systems directly. On the same ts3server instance you can run several virtual servers, each listening on its own UDP port.
