What are the best practices/cautions involved when pre-staging 3CX server builds offsite? We build customer systems in house then deliver to the customer configured and ready to go. I understand that there is a connection between the mac address, private IP, public IP, public FQDN, public certificate, and license that needs to be solidified during the installation process. I can deal with setting the system's permanent private IP during staging if necessary. Do I have to temporarily allot one of my office's public IPs and associate my customer's public FQDN with my address, then associate them with the license and certificate during my pre-stage setup? Then do I need to follow some process to change all of this when I deliver it to the customer site? Will anything break?
