Caller ID is "16179816244".  The default format is (xxx) xxx xxxx, so they have tried to look vanilla but have failed.  They leave no message.

I call back after hours (using *67 to block my number).  I hear the following, "Your call has been forwarded to an automatic voice message system.  The mailbox belonging to <pause> is full.  Please, hangup.  Are you still there?  Goodbye."  Once I called back and got a fax machine sound.

So they spoofed their caller ID.  They fail to identify themselves.  They have no way to leave a message.  This smells like a SCAM.
