I’ve just upgraded FreePBX from 5.211.65 to 6.12.65 (http://wiki.freepbx.org/display/FD/FreePBX-Distro-5.211.65).
Then I tried to upgrade modules. But saw some misunderstanding with module “System Admin”. “Module Admin” show me that to upgrade “System Admin” I should buy it. But AFAIK “System Admin Pro” is not free. But “System Admin” is free.
Few weeks to months ago I got an email saying that because of the latest hack of some PBX systems the Admin module will be given for free , but I seen this is not the case after a few weeks still It was had to be payed in order to get the new features like OpenVPN server in the WEBGui.
