Yes. Now called 'call ads.' They show only on phones, and the click IS the phone call, with no website visit in between. For call-first businesses (emergency trades, appointment booking), they remove every step between the search and the ring.
Two disciplines make them work: run them only when someone answers (schedule them to staffed hours. Every missed call is a paid miss), and turn on call reporting so calls are counted like the conversions they are.
Compare them against regular ads with call assets: many businesses find standard search ads with a prominent call button match call-ad volume while ALSO capturing the form-fillers. Test both; keep the cheaper cost per conversation.
