I'm just scratching the surface for VoIP with Elastix. I notice that Elastix 2.x is "open source" but 5.x is proprietary?
Looking into licensing from the manual on Elastix brings:
I don't want to get entangled with some sort of lock-in. Rather, the flavor of lock-in I prefer has GPL attached to it. Elastix is, or has, moved away from GPL? The version I'm on uses CentOS.
Right now I'm running Elastix 2.x remotely, just wondering whether it's the best choice or will be a licensing dead-end.
License GNU General Public License(2.5) Proprietary (5.0)
Elastix 2.5 is free software, released under the GNU General Public License. Elastix 5.0 is Proprietary released under the terms of the 3CX license
In 2016 the Elastix project was acquired by 3CX. With this acquisition the Elastix Distro versioned at 5.0 was switched to a branded Debian install with the 3CX platform
