Received several of these calls in a row. Ins't it interesting, that my Magic Jack shows this:

702-359-5624 then in the phone it shows: v221-120-440000551 then it called again and next is: 702-359-5624 v221-121-5380000551 but the third time it called I don't believe it showed the V# whatever in the world that is. I really think this is some sort of Nigerian scam call or a scam from overseas.

Receiving phone calls from this number and answered it twice. They said it was a survey of something for "educational purposes" and asked me a bunch of questions. They already had my email address, my actual physical address, and of course my phone number (which was my cell phone number). They proceeded to ask if i graduated high school & what my highest grade completed was. Then, the red flag, they asked me my birthday. I hung up then and there. I figured my social security number was next because they asked if I was a citizen of the USA. The second I asked who this was and they told me the same thing. I hung up right after. It is all fishy and I shouldn't have given them the time of day. This is a scam because even though it says it's a Vegas number both times I answered it they had an Indian accent.

This number continues to call me periodically every 2 hours or so. I answered the first time and got some machine (I'm expecting calls from certain people) and now regret doing so. I highly suspect this to be a scam based in Nevada.

I received numerous calls from this number yesterday. I do not recognize the number, therefore, I did not answer. Caller would not leave a message. I suspect it has something to do with a scam for a free dinner at Spaghetti Factory in Vancouver, WA.
