Telecommunications Relay Service [TRS]

Telecommunications Relay Service or TRS

711 for TRS is not available by default on our Switch, but can be enabled by Voradian Support Center. If you need this service enabled, please contact our Support Center via support ticket or by phone.

How does TRS work?

TRS stands for Telecommunications Relay Service. This is a free service to permit persons with a hearing or speech disabilities to use a Text Telephone (TTY) or other devices to call persons with or without such disabilities.

Once TRS is enabled, anyone can dial 711, whether dialing to a TTY device or calling from a TTY device. They will be connected to an Operator to make a call. The operator will place the call and give the far end called individual instructions on what to expect on the call. The TTY user will type to the operator, and the operator will verbally relay the message to the other end. When the other end responds, the operator will type the command back to the TTY user.

TTY Telephone?

TTY stands for Text Telephone. In VoIP, These are typically analog devices that would connect to an ATA in order to dial 711. The text-based message can be sent to another TTY device that is designed to receive the signaling or can be sent to the TRS to relay the communication to voice. There are also computer-based TTY software, such as ipTTY, that serve the same purpose.
