Yeah, I got the same call just now, we've been getting a number of calls like this - when I trace the numbers some are from Russia, India, and they are all the same - there is no one there.  We are a business and I am frustrated beyond with this.  There is no one on the other end - its a long hissy message - tonight I left the line open to see if it would kick in because I was about to offer someone an ear full.  Guess I have to save my breath for another time as no one ever did answer.  What is going on with this type of call?  Who is it, what do they want and why?  We are based in Nova Scotia.  If someone out there knows how to stop these calls, I would like to know.  Thanks for your time.
