I just received a call a few minutes ago from this number. There was definitely someone there, but after I said hello for the second time the person hung up.
Received call today from this number. No response on the line when I answered. Voice mail may have picked up before I got to it, but there was no message left.
Found out what this number is. Supposedly it's the outbound number for a military base in Iraq. I have a friend stationed in Iraq, so I guess it may have been him calling. Here is where I found out the details on this number: http://800notes.com/Phone.aspx/1-240-336-0296
