This 3CX image does not work
3CX is a great system. However we have never been able to get this pre-loaded AWS image to work. It never restores our backup config properly. We've tried it many times with different clients. Tried this again because it says it was updated in Feb of this year. Well we are back to loading up a Debian image and installing 3CX at the command line.
Try deploying via 3CX Console from the partner portal. We've recovered before this way.
Could you specify what will not restore with this backup?
