I received an email from Computerworld with a link to download a guide to compare business phone systems. I have a customer looking at phone systems so I downloaded the guide and forwarded it to them.
Within 10 minutes this number started calling. "Compare Business Products" is the name of the outfit. Per the follow up email that they sent: "Please note we do not sell phone systems. We simply offer a free, no obligation service where we match customers with qualified companies in your area based on your needs! I look forward to hearing from you soon!"
