Reading Time: 10 minutes In the previous post I’ve describe what is 3CX Phone System and how install it. But the installation part is really easy and short because the most interesting part is the configuration. Compare to the installation flow, the 3CX Phone System configuration wizard is a little more complex (at least require that you think on what you are doing) but is better structured. The wizard will appear the first time you will walk you through a number of essential tasks that you need to do in order to get your system up and running.
