Can't bring up phones

We have installed the S/W. The GUI works fine but I can’t get a phone to work. I am testing with an XLITE. I have read all the docs and still no luck. Is there something I could have missed?

any help would be great. I have also loaded TRIXBOX and there are no issues. My problems are just with free pbx?
