A Class 4 PBX? What it is? In short, a class 4 PBX is the one that interconnects different PBX. It is very common that this class of PBX doesn't have contact with end-users. The perfect example of class 4 PBX is the carrier that sells IP telephony companies the DID's (origination) and outgoing gateways (termination). There are more differences between a 5 class and a 4 class PBX, my article about that covers it.
For the sake of this article, let's pretend everybody knows what is a class 4 and a class 5 PBX. Let's discuss FusionPBX. FusionPBX, out of the box brings let's say, 90% of all the needs a class-5 PBX needs: voicemail, IVR menus, time conditions, queues, and a lot of more features that are useless if all you want is a class 4 PBX.
Today I have published a very curious RPM. the FreeSWITCH Asterisk app_amd RPM 0.0.0 for CentOS 6, 7 and 8. This RPM claims to use the same technique of the Asterisk app_amd module.
I have tested with FreeSWITCH 1.10.5 and it seems to work very well. To find it, just do a yum search freeswitch-application-amd.
As I have written before, after more than five years it was time to retire from hard work my trust old laptop. I decided to get an HP Omen. I must say the hardware is quite amazing and to get the best of it I installed Mageia 7 (current version when writing the articles).
Recently I have been getting into photography (I will write about that later) and of course, getting the software to develop RAW files is a must. I think Darktable is the best for it; however, this kind of software is really heavy, even this super powerful laptop with 12 cores at 3+ GHz got dizzy. Fortunately for us, Darktable supports GPU processing which offloads the CPU and displays the images almost right away.
Configuration to make this possible is kind of tricky. I will put here my notes hoping it will help other fellows Linux photographers. My notes are on Mageia but I am confident that anyone could apply them to their own Linux distribution.
It took me weeks to figure it out.
