Just received a call from this number, but they did not leave a message.

I also just received a call from this number a minute ago. They did not leave a message.

I just got a call and answered it.  The man was mostly unintelligible.  He sounded like he had an accent, a speech impediment, or both.  He asked my name.  I said, "You called me.  Who are you."  He said something about something or other in Washington, DC.  I tried several times to figure out what he was saying, then hung up.

I have got two calls from this number on my cell phone.  I've been at work both times and have missed the call.  They don't leave a message.  I've done some research on the internet and the best I can tell, its a scam for government grants.  I continue to ignore the call.

Called yesterday and today. Did not leave message.
