SvxLink is a ham radio repeater controller and a general voice services system with features such as EchoLink and voice mail. The biggest change in this release is a rewritten audio infrastructure which have made it possible to implement new features. See the ChangLog for all the details.
The SvxLink project can be used as a replacement (and more) for the Windows only closed source EchoLink application. To get started, have a look at the SvxLink homepage: http://svxlink.sourceforge.net/
