Resume Resume Editing!!

So I am pimping my resume, a little title inflation here, a sprinkle of self praise there. Actually I am trying to trim it down quite a bit because it confuses most people who pick it up. Most people don't know what a VoIP IAX2 trunk is. I still can't quite come up with a unified writing method for all descriptions of previous jobs. I want to be informative but not over detailed. Open to any pointers.

Oh yeh! The best part is I am being payed to update my resume to comply with federal guidelines on a project I am on. Yay!!
