IP Relay A text-based Telecommunications Relay Service (TRS) that uses the Internet Protocol (IP) based Internet rather than a traditional public switched telephone service (PSTN) connection to communicate. A speech- or hearing-disabled person initiating an IP Relay TRS call uses a computer or other text input device to call the TRS relay center over an Internet connection and give the communications assistant (CA) the destination telephone number, which the CA uses to place a traditional telephone call.The CA then serves as a translator, relaying the text of the calling party in voice to the called party, and converting the voice of the called party into text for the benefit of the caller. See also Internet, IP, PSTN, and TRS. |
