I've stumbled across fsgui a few times, ( http://wiki.freeswitch.org/wiki/Fsgui ), and am happy to report the windows release of this program works flawlessly!
After toying with the windows version myself and a few other community members wanted to see this application running in linux as well.
I downloaded the fsgui.tar.gz and unzipped it to /tmp then installed the following packages on Ubuntu 10.04, which also installed related dependencies:
libqt4-dev
libqt4-core
