Leonard convinced magazine owner Carl Ruderman to purchase more of these numbers and the business began to be successful using the magazine to promote the service.
Leonard herself was surprised at the success of these numbers.
Leonard recorded her own voice informing callers of the contents of the next issue of High Society magazine before its publication.

By the end of the 1980s, nearly all of the major local phone companies in the United States, plus the major long distance carriers, were actively involved in the adult chat line business.
The telephone companies would provide billing services for chat line companies.
Unused minutes were rarely usable on a second call.Originally, per-minute billing was provided by phone companies (in the U. There was, from some services, an attempt to keep the caller aroused but short of orgasm, so he would spend more money.(This attitude still survives among some providers.) When public (mostly female) pressure forced the phone companies to stop providing this service to sex workers, a transition was made to a manual method: pre-paid blocks of time, 10, 30, 60 minutes, whatever the customer would pay for.With the progress of technology it became more practical, convenient, and economical for providers to work out of their homes.Human dispatchers — female, except for gay male phone sex — answered the advertised phone numbers, processed payment via credit card, chose who of the available performers in the dispatcher's judgment best matched the clients' fantasy (grandma, black girl, college girl, etc.), and connected the client with the provider. Either could hang up, though some services put economic pressure on providers not to do so.If a customer disputed a charge, the telephone company would usually “forgive” the charge but block the caller from calling any other chat lines.
