I too received a call from that number with no message! Could not find out who it was and I AM on the do not call registry!

This number called me and left no message. When I attempted to call it back immediately, an automated message came on that stated "your call cannot go through". This leads me to believe it is a solicitor of some type. I am on the "Do NOT call list", so I will have to see how to report this.
