I answered to this number, and after numerous back and forth "hellos", the response from the other end of the line was, "Hello?  Hello?  This is a company."  I couldn't understand anything after that, the line was very static-y, so I hung up.  Good to know I had a "company" calling me!  They called 3 times in a row before I answered it, as I don't generally answer numbers or area codes I don't recognize.  I called back, no answer, but got a voice mail.  I did not leave a message.
