Among TeamSpeak's incredible range of features are crystal clear voice communication, cross-platform design for both the client and server, a built-in web based administration control panel for the server, and a highly scalable user permissions system. In addition, the TeamSpeak server can spawn multiple instances or "virtual servers" from a single server session, thus easily scaling to suit the needs of your community or social network. The TeamSpeak server has a native SQLite database but can be configured for use with MySQL, and has built-in command line query capabilities allowing practically limitless automation and scripting possibilities. Lastly, our next generation TeamSpeak 3 SDK offers a complete integrated solution for online games, virtual worlds, social networks, military simulators, education, or any environment where up to thousands of users require crystal clear voice communication.
