In 2020 when RedHat took over CentOS, many predicted it was with the intent of destroying it, being derived from RHEL it was a direct competitor, some say those people have been vindicated, as that's exactly what RedHat did, and its short life-span replacement, CentOS Stream, is just another Fedora, this left FreePBX devs in a bind.
Asterisk and FreePBX allow for a myriad of customisations, some of these however need hand editing asterisk files as well as some FreePBX configuring (due to how FreePBX uses its database and overwrites some asterisk files), so some things you just can't entirely do from within FreePBX, or in asterisk (when using FreePBX that is), like set up Lenny, or provide a Weather service.

By default, ChanSpy, a supervisor function that allows you to monitor
other peoples calls, is enabled and can be used by anyone, yes, anyone, who's phone is logged in to a FreePBX system that has this feature enabled.
Sangoma don't allow you to secure it out of the box, instead, they try sell you some commercial module (that's about AU$145) that allegedly sets a PIN. But you can do it for free!
We all (hopefully) backup our PBX's - our config files, databases, even system audio and logs, some of this can be backed up hourly, daily, or weekly, so in all likelihood, you will have at least two backup processes probably more, but where do you back them up to?
Local storage? It's fair to say nearly everyone uses this, but is that the only place you have them? What if your disks fail? A lot of good those backups are now you can't access them!
FreePBX, being a front end to Asterisk, allows setting multiple time periods under a single Time Group, usually for public Holidays and such, we call this Holidays - I know, so original
This article concentrates on Queensland, in particular Brisbane, Public Holidays, since only a few holidays vary between states, it will be easy for you to change to suite yours if you need to, likewise international readers, where many don't observe Show Days, ANZAC Day, or Easter.
Playing music on hold (MoH) on your phone system whilst your caller is waiting to connect to the person or department they are after, or whilst someone ducks off to get some information, is a given these days, no-one wants to sit there and listen to silence, or nothing but the sound of keyboard tapping for 5 minutes.
Am I still connected? Did they forgot about me? Hrmm... is this thing still working? C'mon aren't you done yet?
