However, I found a post from 2017 that had the fix.
Needed to run: yum install iSymphonyServerV3-fpbx
The post was actually from you Igaetz.
It seems to be working now without the additional steps in your post. Do you think I need to dig into this further?
I haven’t actually logged into iSymphony yet, but I am able to pull up the login interface. I also purchased the licences and they successfully activated.
