Actually, http://www.google.be/search?q=%22(760)+930-0100%22+%22760-930-0100%22&hl=fr&start=0&sa=N shows that this number is used by a number of companies - once I called 3 weeks ago a woman explained me that she works as secretary for all the building, her number is a central number, part of her job is to dispatch calls to the person you wanna talk to.
