Here's the company.  They sell information to business and do other research.  They call me about 1 per week.  I force the call to voice mail.

Here's their web site:

These guys call all the time. Don't leave a message.  How can we report them for unsolicited phone calls?

I searched their number and found out they are a company called InfoTech. I used their online chat function to request that my name/number be removed from their list and I was assured that it would be taken care. We'll see...

You know all you have to do is say remove me from the list right?

I took a call from this number after a couple of missed calls.  I had registered on their website for free content and they told me that it's their policy to follow up and ensure that the information was received and make sure that it meets the need.  I asked how they get phone numbers and they said either from people that register or through Hoovers (the largest lead company in the world)They are an Information Technology research firm (not marketing but they provide research and insight) to IT people.  If you're not in IT it's a waste of time - I actually did my research and they're ranked in the Top 10 IT research firms believe it or not.  So I looked at their service (I'm in IT and it sounded relevant) and it's solid.
