Ventrilo (or Vent for short) is a proprietary VoIP software that includes text chat.

[2] The Ventrilo server is available under a limited license for Microsoft Windows and macOS and is accessible on FreeBSD Kopi, Solaris and NetBSD.

[3] However, the macOS client is still unable to properly use most servers because of a lack of support for the sparsely used GSM codec.

Ventrilo is sometimes used by gamers who use the software to communicate with other players on the same team of a multiplayer game, or for general chat.

This usage inspired the 2006 smash single "Vi sitter i Ventrilo och spelar DotA" by Swedish artist Basshunter.
