Pay per Call works by charging the consumer a fixed price per call. The user will ring in to a premium rate number which you advertise, he will be advised of the charge of the call and is asked to stay on the phone for a pre-determined amount of time until billing is complete. This solution is mainly used for virtual credit top ups and one off payments i.e. adding calling credits or topping up e-wallets, a one off payment to purchase a download of a movie, a clip, a song or any kind of digital content.
