Have received multiple calls.  If we answer there is noone there.  Apparently, this is a robo-call.  If we do not answer, they leave no message.  CID says "Weehawken NJ"

Calls a couple times a day and never leaves a message and when you answer nobody is there.

Anonymous received a call from 201-537-5973.  

It went like this,
[caller]:   "Is this Billy Bob?"
[Anonymous]:  "This is Billy Bob Johnson."

I called the number back from a little-used cellular phone.  The female voice on the recording said it was the National Republican Congressional Committee and they were trying to keep the house majority, blah, blah.

Just received this call @ 3:15 PM. Did not recognize, did not answer. Obviously, a prank call.

ALSO GOT THIS CALL AT 4PM, DID NOT ANSWER,NO MESSAGE
