Giving 3CX A Shot ... and fail

I'm having a lil problem with registration on 3cx. Here is the output:

Not quite sure what's going on, first time using this software and unsure why it's using 10000@Generic Voip Provider but here are a couple screenshots of the settings that are in there right now:

Not sure what this Virtual Extension Number should be, I tried the number I was assigned, but that didn't seem to work either, 3CX was giving me some message saying it wasn't valid.

Any hints on this stuff?
