lol.
Some phone companies do have affiliate programs where you get paid on the basis you are talking about. I remember JustDial used to, and there were many ads from their partners/affiliates in the natural and paid search engine results.
Not sure how profitable it is nowadays with the cost of calls being so cheap - can often ring most of Europe and North America for a couple of pence a minute, so doubt the affiliate would make much.
But definitely worth exploring, particularly if you earn the commission on a recurring basis.
