I am successfully using an asterix (trixbox), I have been looking at security and as such I removed my remote extension, I have also looked over the security recommendations issues by the trixbox.org wiki's. I am am only used to using windows based software and as such I set-up and control the system using the http interface.
I have been talking to a friend who was starting the have problems with hacked calls on a remote extension, he changed his system to 3cx.
Is the 3cx system good and is it complicated to secure?
Any reviews or comments I have seen on 3cx are good but these are on the 3cx website, so I take them with a pinch of salt.
