Telecommunications relay services

Many scams use telephone calls to convince the victim that the person on the other end of the deal is a real, truthful person. The scammer, possibly impersonating a US citizen or other person of a nationality, or gender, other than their own, would arouse suspicion by telephoning the victim. In these cases, scammers use TRS, a US federally-funded relay service where an operator or a text/speech translation program acts as an intermediary between someone using an ordinary telephone and a deaf caller using TDD or other TeleType device. The scammer may claim they are deaf, and that they must use a relay service. The victim, possibly drawn in by sympathy for a disabled caller, might be more susceptible to the fraud.
FCC regulations and confidentiality laws require that operators relay calls verbatim, and that they adhere to a strict code of confidentiality and ethics. Thus, no relay operator may judge the legality and/or legitimacy of a relay call, and must relay it without interference. This means the relay operator may not warn victims, even when they suspect the call is a scam. MCI said that about one percent of their IP Relay calls in 2004 were scams.[
Tracking phone-based relay services is relatively easy, so scammers tend to prefer Internet Protocol-based relay services such as IP Relay. In a common strategy, they bind their overseas IP address to a router or server located on US soil, allowing them to use US-based relay service providers without interference.
TRS is sometimes used to relay credit card information to make a fraudulent purchase with a stolen credit card. In many cases however, it is simply a means for the con artist to further lure the victim into the scam.
