I want to thanks the FusionPBX community for their sponsor. Without the given support this new capability wouldn't be possible. Today I have published into the FusionPBX some pull requests (for FusionPBX 4.4 and 4.5). This new capability gives your PBX the parent-child domain. This means an admin user will be able to manage more than one domain without being super-admins. The best-case scenario for this is new capability is the reseller one.
Once it is configured, you may give access to a reseller and let him manage their domains. I will explain how it works.
I have forgotten to make this public, but from some days ago the LibKS 1.3.0 RPM for CentOS 7 and 8 is available. LibKS is defined by FreeSWITCH as a cross-platform kitchen sink library. It is needed if you want to enable signalwire module.
So after doing some readings, I saw that there are several advantages to using TokuDB over InnoDB when we are dealing with huge databases. The thing here is that using that TokuDB requires jemalloc to run. Since CentOS 7 and 8 are systemd enabled using the methods advertised on most websites won't work.
I will write here what I did to enable it,
