Who called from 4082142151

I have been getting calls from this number

We are getting calls from this number, will not answer...so many scams out there.

getting this call many times,not someone I know how do we stop it?

I get calls from this number every day. I answer, and no one ever says anything. How do I get rid of them?

Just got a call for 408-214-2151 Caller ID; San Martin, CA TO Campbell California.
THIS WAS MINUTES AFTER I emailed a message to a friend today about our lunch date.

I have also experienced this after emailing LA and Austin... Is this a new method of data mining our IP: Address?
