Some Product PPCs have expanded into the service space while other service engines operate in specific verticals.

Pay per call Similar to pay per click, pay per call is a business model for ad listings in search engines and directories that allows publishers to charge local advertisers on a per-call basis for each lead (call) they generate. The term "pay per call" is sometimes confused with "click to call". Click-to-call, along with call tracking, is a technology that enables the pay-per-call business model.
Pay-per-call is not just restricted to local advertisers. Many of the pay-per-call search engines allows advertisers with a national presence to create ads with local telephone numbers.
According to the Kelsey Group, the pay-per-phone-call market is expected to reach US$3.7 billion by 2010.
