Hi, many customers want to try 3CX Phone Sysyem in a test lab before purchase it. In many cases the network lab is in a different vlan (with different ip addresses). So it will be simple to change vlan and ip address of 3CX server after tests and put it in production environment without effort. But at the moment is not possible because we have to reinstall another machine (OS, pacthing, 3CX software, service pack, updating templates....etc..) and restore settings. Thanks for your help.
