vicidial.org

Is there a SVN or git repo for Vicibox hosted somewhere?

Nope. Just a folder of old releases. Note that ViciDIAL is open source. ViciBOX (the installer), however, is technically not open source, but it's still free (and the source code is on the .iso ... but the "construct" used to create the SuSEStudio .iso, and modify it, that's not included!).

So you can download any old version of Vicibox from Vicibox.com here:
http://download.vicidial.com/iso/vicibox/server/

But the ability to rebuild using SuSEStudio remains with Kumba (AFAIK)

Thanks Bill!
