If you are into Linux and Photography (some of us are) and you, like me, have a not very old Canon camera, you may see that the RAW files are not longer CR2 files, but with extension CR3. CR3 raw format is the new replacement for CR2 that comes with all Digic8 chipsets. In my very specific case, with my Canon 90D.
I was amazed by the quality of this camera (I come from a Canon 200D aka SL2 that has a Digic7 chip). Canon did a good job from version 7 to 8. However, here it comes the issues, I saved my photos in CR3 format, and when going to my desktop, not KDE, nor Darktable (current version 3.2.1 when writing this article) were able to recognize it. Windows is not an option for me.
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.
