I'm on the same list you are. My guess is they're just picking up fake VOIP numbers and using autodialers to get everyone within a few minutes. I always get a call on my cell, then immediately my work phone. My parents and one of my friends gets a call every time too. Everyone knows it's a scam and they hang up and try not to blame me too much for using them as "references".
Assuming anyone ever investigates these numbers, they'll probably find them hosted by a website that will have trouble identifying the owners of the accounts.
I have a hard time understanding why these scammers think anyone who doesn't answer the first time would fall for it the second time (or, what is this, the sixth?). The longer they piss people off, the more likely they'll get caught.
