Got Irritating Weird Phone Calls?

For weeks I have been getting calls from this phone number:  (301) 223-0096.  They do not leave voice mail, they do not respond when I answer the call, and there is no response when I dial their phone number.  A reverse number search revealed that other people are getting calls from this number and trying to figure out where these calls are originating from.  What's going on?  Anyone out there know?

I don't want to float any paranoid conspiracy theories, but...why an I getting these calls every day and sometimes twice a day?  The caller ID reads, "UNKNOWN NAME" ....  Give them a call and see what I mean.
