Just had this number call me too...I didn't answer...but sounds like I am glad I didn't.

This is most likely the company Local Splash--I blogged about them recently.  http://blog.flexresourcing.com/2011/01/some-thoughts-on-local-splash.html

We have been getting calls from this number for a month or more, several times a week, on a residential line on the DNC list. I have never answered them until today. After a long delay, a woman speaks and asks for me by name. I answered, "speaking"! To that, the woman says "NEVER MIND" and promptly hangs up!

Yep. The asylums are being emptied!

I have received a call from 657-206-5077. Others have claimed Brent Larsen is cold calling for identity information and is affiliated with Google. 14u2trust reports all unwanted calls to help others save time & energy. I hope that everyone will start reporting unwanted calls. By contacting your local phone company you can put a trace on unwanted calls and report that information online.

i answered they hung up. why make the effort to call then bail. lame.
