For those that are following along at home, this was originally an Elastix system.
This is where the problem is - Elastix machines can't be upgraded outside of the Elastix ecosystem. This is nothing unusual, if you add Epel to your FreePBX Distro machine and upgrade Asterisk from there, it'll break stuff, too.
We do try to keep stuff a lot more standard, though, so that if you DO decide to add epel, the absolute worst that would happen is Dahdi hardware breaking. We hope
