Quick Install script is full of bugs, and does not install

I have tried the script on both CentOS 7, and Debian 8 on minimal installs. On both it failures miserable. There are no guidelines on what the starting system should have on it. Was any testing done with that script?

This is what I am seeing on Debian 8

(In this case, FreeSwitch was not even selected to install)

In the end, there is not even anything listening on port 8089;
