Google hack search for the area code, then number, found a website containing the number in the appropriate location, then dns lookup to see who registered the site.
Like I said, she may not be directly involved, however, she's somewhat responsible in that the site content posts the number we're having an issue with.
Ok - Dug a bit deeper and found Anita's resume. She's a web designer and graphic artist by trade, and does a little IT development, so it may be that the info provided was based on a publicly available web site that wasn't finished. Benefit of the doubt: could be a template design waiting for additional numbers to fill in the zero's - if this is the case, the site should never have been made available.
I'm not going to pursue any additional info unless I continue to receive calls from this number.
You guys are dopes, how the heck are you researching and looking up a phone number that does not exist? There is no 000 exchange permitted or used anywhere in the U.S. So I would suggest to people that these posters are simply posting the info of people they want to be harassed in some way, or they are just totally off the mark. This is a SPOOFED caller id, that's why you can't call it back, it is an invalid phone number.
