Not anymore those got removed when we got rid of the POTS lines.

Turns out the updated kernel doesn't like the Dahdi card. So support had to roll back the kernel version until the engineering team fixes it. No kernel updates for me until then.

How can you get kernel updates on CentOS? I thought you'd only get security patches on the same kernel. Exactly for the reason to avoid the problem you had.

Did you mean on FreePBX?

I have Update Manager module and this is the kernel header they rolled back to:
kernel-headers.x86_64 3.10.0.1127.10.1.el7. The newest release is 3.10.0-1127.19.1.el7 which is the one that has the issue with my Dahdi card.

Total Linux Noob here - is that really a new kernel or just a patched kernel? Hell is there a difference?

Good question. Maybe @JaredBusch can answer that one.

Every patch is a new kernel.

3.10 is the linux kernel and 0 is the minor revision. Those numbers are from the linux kernel team. 1127 the patch number (Redhat's I think). The rest of the numbers is redhat's numbering scheme.
So Linux kernel team makes the kernel. And they maintain it for a couple of years - if it's a LTS kernel.
Redhat takes the stable kernel and adjust it for their use. Then Redhat maintains their kernel themselves by backporting security patches to it forever - long after the kernel is EOL.
That's why I'm surprised it broke hardware support because that exactly why Redhat sticks to the same old kernel for many, many years. They don't want to break anything.
Here you can see what kernel version each release is using.

Doesn't FreePBX use their own distro though? Or is that something different?

I don't know. I was always under the impression it was CentOS, which until recently is the same as RedHat Enterprise Linux.
I'm sure @JaredBusch knows more.

FreePBX is Sangoma 7, a fork of CentOS 7.
They had a private alpha of FreePBX 15 or 16 built on CentOS 8 that was never public. That was killed when RedHat killed CentOS 8.FreePBX 16 is still Sangoma 7, but with PHP 7.4 ported in and a few other updates.
There has been no announcement yet, but a few threads on, choosing a new fork to go forward with.
