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.The provider provided (say) 10 minutes of service, but got to keep all of the money (say 20 minutes).When the Internet got relatively mature, sale of any sexual service not involving a minor could be made to anyone not a minor.Once means of transmitting payment were developed, phone sex turned into primarily a commercial activity, with customers (overwhelmingly male) and sellers (overwhelmingly female).Due to the potential for emotional intimacy between those who have engaged in phone sex, it is a matter of some debate whether phone sex is to be considered infidelity when involving a person outside of a committed personal relationship.
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.If a customer disputed a charge, the telephone company would usually “forgive” the charge but block the caller from calling any other chat lines.By 2007 only Verizon, Sprint and AT&T remained in the chat line business in the U. By 2007 Verizon and MCI had merged and only a few chat line companies remained active as a result.Typically the telephone companies would bill callers to chat lines and then remit 45% of the money collected to chat line operators.The telephone companies placed the chat line charges on a customer's local phone bill.
