The vast majority of modern services in the United States use toll-free numbers whereby clients can dial up to request a call with a particular performer using credit cards, Automated Clearing House systems, and a variety of other billing methods.

There are still some services that rely upon premium-rate telephone numbers (e.g., 976 and 900 numbers) for billing purposes, although this practice has been largely abandoned due to the high rate of fraud associated with these lines and the inability to dial 900 and 976 lines from cellular phones.

Software platforms were custom written to handle money collection and transfer, connecting caller and sex worker though neither could see anything but the platform's phone number, and metering the connection.

Details vary significantly from one platform to another, but the provider may be given a personal page on the platform to use however she (sometimes he) wishes.

Nevertheless, phone sex should not be confused with prostitution wherein money is exchanged for real life sexual services or physical interaction.

The editor of High Society magazine, Gloria Leonard, is credited with being one of the first people to use "976 numbers", then "900 numbers" for promotional purposes and soon as a revenue stream in the adult industry.

Leonard recorded her own voice informing callers of the contents of the next issue of High Society magazine before its publication.

Later she recorded others such as Annie Sprinkle "talking sexy".

The sexually explicit conversation takes place between two or more persons via telephone, especially when at least one of the participants masturbates or engages in sexual fantasy.
