Most of the best phone sex services are a managed network of dispatchers (live or automated) and erotic performers who process payment information, verify the legal age of their clients, and perform calls in their own homes on their own telephone lines. Many phone sex operators use service bureaus and phone sex directories to advertise their services.

The vast majority of modern services 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. As a direct result, most telephone companies allow their customers to block outgoing calls to premium-rate telephone numbers. In 1996, the FCC changed regulations on 900 numbers to address abuse of these services by minors and fraud concerns.

Another type of service is the live callback, where the customer contacts a receptionist who tries to find a suitable woman to call him/her back - hence callback.

Like other sex industries, the sex warszawa industry has taken on new dimensions in the Internet age. There is an ever-growing community of independent phone sex operators who engage in self-promotion. This self-promotion can involve a personalized website where the phone sex performer lists their specialties and services, various methods of advertising (via the traditional methods listed below, or on organized third-party network sites that provide a basic level of privacy for performer and client alike) and/or surfing of sexually themed chat rooms for interested clients. This increase in independent operators is largely because information regarding the business is being filtered to the mainstream public. The once close-lipped industry, traditionally inaccessible to amateurs is experiencing a demystification period and resource sites, community forums, and reference materials are more readily available.

Phone sex service providers typically advertise their services in men's magazines, in pornographic magazines and videos, on late-night cable television, and online. Some phone sex services use state-of-the-art customer acquisition techniques such as active database marketing to reach potential clients. These advertising methods almost invariably target men, the primary consumers of phone sex services.
