Insanely quick question, do flyers work for Pay per call?

I'm promoting some businesses. I was wondering if anyone had any luck with using flyers to generate phone calls, I'm going to try it whether it will work or not, but if anyone has any success with it, do you have any tips? Thank you

4-5 years ago i was made 500-1k$ daily on IPRN. I didnt tested out recently. But maybe those ppcall services are in same old system then i can teach you some trick hehe. pm me if u interesting.
