Pay per call blackhat traffics

Hello,

Is there anyone who is doing pay per call marketing and making a massive profit? In pay per call marketing is there any secret traffics or blackhat methods available for call generating? Hear about classified system but don't know how to do that. If anyone can help, share this here or inbox.

Thanks
