ITRS (Internet Telecommunications Relay Service)

iTRS (Internet Telecommunications Relay Service) is a generic acronym for all Internet based forms of TRS; refers to a telecommunications relay service (TRS) in which an individual with a hearing or a speech disability connects to a TRS communications assistant using an Internet Protocol-enabled device via the Internet, rather than the public switched telephone network. Internet-based TRS does not include the use of a text telephone (TTY) over an interconnected voice over Internet Protocol service.
