What is "ventrilo"

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

The Ventrilo client and server are both available as freeware for use with up to 8 people on the same server. Rented servers can maintain up to 400 people. The Ventrilo server is available under a limited license for Microsoft Windows and OS X and is accessible on FreeBSD Kopi, Solaris and NetBSD. The client is available for Windows and OS X. However, the OS X client is still unable to properly use most servers because of a lack of support for the sparsely used GSM codec. Flagship Industries does not offer a Linux Ventrilo client. Third party Ventrilo clients are available for mobile devices, such as Ventrilode for iPhone and Ventriloid for Android.

Ventrilo supports GSM Full Rate and Speex codecs.
