I want to understand the propriety of the various FreePBX modules
There are the legacy ones that are unencombered and others that are not so much,
From the website http://www.freepbx.org/ it states quite boldy :-
FreePBX is an easy to use GUI (graphical user interface) that controls and manages Asterisk, the world’s most popular open source telephony engine software. FreePBX has been developed and hardened by thousands of volunteers over tens of thousands man hours. FreePBX has been downloaded over 5,000,000 times and estimates over 500,000 active phone systems. If you don’t know about FreePBX, you are probably paying too much for your phone system.
And If I download it from scratch it is exactly that, truly “open source” just like Asterisk.
I have been told that this distribution is a FreePBX distribution so I assumed that it would be also “open source” but I find in:-
however, some accompanying bundled software may be released under other licenses. Please see the source code for the exact licensing.
There are modules that are installed that are not quite open and require Zend , while I don’t have a problem with that directly as everyone needs to make a buck, that encumberance makes restoring or migrating one system to other hardware a problem as yet un-acknowledged.
Quoting the above need to examine the source code for the other licenses, for example the sysadmin module, is a little difficult as it is encrypted, a bit of a Catch-22.
Can any authority please clarify what are the licenses that we accept by default when installing this distibution and how the licensing of the free but proprietary modules can be migrated?
