Great info.
Called Mr Cohen and he actually picked up his cell himself, not voicemail.
He seemed to be a decent guy. Talked to him for about 10 minutes.
He is bothered that he pays a company to provide him a list of valid (not on do not call list) numbers that his business can legally call, and he gets about 90% good numbers and 10% bad ones (numbers listed on do not call list). He has changed companies 10 times and they all lie. Once he got a list and 50% were bad numbers. So as a business I understand his side, and genuinely want to solve the problem of his side of this vicouse cycle of madness.

I don't mind getting a call every once in a while even though I am registered on the do not call registers, however when I do pick up the phone, or even bother to call them back to see who it is, there is never anyone there...I don't get it. So now I am more annoyed that I get 10 calls a day, leaving 10 hang ups, and I can't make them stop.
