Who called from 9044188341

Got a phone call from "Unknown Caller."  They were doing a survey to see if we recycle at home and the workplace.  Could hardly understand the caller.  He said his name was "Robert" and spoke very broken english.  I hung up on him.

Someone from this # called - hung up - I called same # on my cell phone - they hung up when I said hello.  There is lots of voices in the background.

Called my home caller ID unknown   did not answer when machine picked up
they hung up

Received call at 15:26 Friday afternoon.  I did not answer.  They did not leave a message.

We got a call from this number, it only rang 4 times and they hung up before I answered. Sounds like a survey number. Is there any way to find out what numbers Gallup uses?
