This number continues to call my phone and I would like to report it.  It starts as an automated message from a woman stating that "this is not a telemarketing call" or that it is "unable to disclose the nature of the call by federal regulation".  It then follows by saying please press any button to speak to an operator and before pressing anything it follows with an piercing tone like someone had pressed the button.  I listened the second time and the tone just continued for about a minute without ever reaching anyone.  This same thing happens with this number 612-005-8700.
