ViciBox or GoAutoDial

I am using GoAutoDial 2.1 for past few months mainly for testing. And now I am planning to move to bigger server(s) in production environment. I am not a *nix expert and only know basic stuff/troubleshooting. Now I can some please guide me which flavor I should use ViciBox or GoAutoDial. Some details are
- Not Linux expert, so I have to learn both OpenSUSE or CentOS (though I have used CentOS a few times but still on novice level)
- We will need multiple servers, they can be part of same cluster, or can be separate standalone servers, but will prefer cluster with a dedicated DB servers serving all the dialer/web.
