As others have already pointed out, carriers nowadays mostly do flat rate voice service. When cellular bandwidth is more limited cellular carriers did usually have per minute charges.

It wasn't actually receiver pays. It was each person pays their phone company for carrying their end of the call. It didn't matter if you were the receiver or the initiator.

Note that this is the same model that is used in most of the world for internet service. I've never understood why people find it weird to use that model for phone service but not for internet service.
