It's not enabling or disabling, it's setting it. The OS default is 60. Many cloud providers change this in their own defaults because it impacts other customers. On my cloud instances, I normally set to 10.
I install Centos 7 Minimal on a Vultr VM, and the default was 30.
Often sales people and management will ask, "How do I check my voicemail from outside?" I always recommend that they enable voicemail to email, but for those that want it, you can set up a silent option in the IVR.
What I mean by silent option is that you will add another option to the IVR, but you will not announce that option in the recorded audio.
Add another entry and choose the Destination category of Feature Code Admin and then select Dial Voicemail <*98>
Some people have reported issues using the PJSIP settings with VoIP.ms. I have been using it for months with no problems, but if you are having problems, then you can create a CHAN_SIP based trunk with no problems.
Had to modify the instructions a bit to handle SELinux. The below have been added to the first post already.
Install SELinux tools.
yum -y install setroubleshoot setools
After your system is up and running, reboot. You should hopefully have a problem with SELinux blocking a couple of things.
[[email protected] ~]# sealert -a /var/log/audit/audit.log | grep zabbix
SELinux is preventing /usr/sbin/zabbix_server_mysql from using the setrlimit access on a process.

SELinux is preventing /usr/sbin/zabbix_agentd from using the setrlimit access on a process.
Now that these errors are in the audit log, we can set up SELinux to allow it.
If anyone knows SELinux well enough to create the policies needed without waiting for a fail, just let me know. I will be happy to update these instructions.
