Could be a scam caller -

Hangs-up when you answer.  No background noise, no electronic sounds.

A call back to this number tells you it is not in service.

Hangs-up as soon as you will answer. received multiple calls since 2013-01-18.

Some woman from MoveMyBusiness.com called and asked "Are you still planning on moving your business?"  I didn't say anything and just hanged up, as this business is not moving any time soon.  This could be a form of phone cramming, where the caller tries to place an unauthorized charge on your phone bill.  They probably record everything you say and if you answer "No," to their question, they could edit the query so that you're answering something along the line like "Do you have any questions about the service you signed up for?"  Just another scam to watch out for.

I am a business owner and they called.  Never left a message.  Thanks for the information.

This person keeps calling...... then hanging up.
