Who called from 3146668303

The person calling says "my name" then says are you there.  Leaves no message & this number is unknown to me.

314-666-8303 called my phone at 8:55pm on Wednesday,  2 Oct 2013.  I did not recognize the caller ID so I let the answering machine answer the call.  There was no message left by this caller.

We've been getting calls from Mercy Hospital from this area code. I went ahead and answered it thinking it might be them. Whoever it was said nothing when I answered and then hung up, which means it likely was not Mercy Hospital as they identify themselves..

10/10 this number called but didn't leave a message????  What does St Louis want?

I keep getting calls from this number and no one says anything.  Clueless????
