This number called our business at 1628 hours.  Caller ID said simply, "Wood Dale IL" so I was suspicious of it being a scam artist.  I let the recorder pick it up but there was no message left.  I blocked my number and called it back and "Tom" answered.  I asked why he was calling our company and he said they were calling service-related companies that might benefit from their software.  I told him we wouldn't (benefit from it.)  He thanked me and wished me a good day.  He might have been cold-calling but at least he was courteous and pleasant, which is a nice change of pace.
