It is required to have clean server without any additional packets installed. Otherwise, the installation script will either wipe the IPTables rules or will not be possible at all.

Default Centos kernel and FQDN pointed to the ip of the server is required. Without FQDN Cloud PBX will not work.

Very important: Single Asterisk or system with a proxy , minimal version of MOR is X12. Multiserver without proxy , minimal version of MOR is X13
