How to make a call using TTYs and Relay

Hi all.

So, I just want to talk about how to use a TTY using TRS (Telecommunications Relay Service), specifically the making a call part.

To make a call:

  • Turn on your TTY.
  • Call 711 on your phone. (711 is the relay number in many US states and Canada for TTYs)
  • Put the phone on the two acoustic couplers.
  • Now, you will need to wait for the relay operator to introduce themselves.
  • When they have finished introducing themselves (and ended their intro with a “ga”, which means go ahead) respond with the number you want to call, and say “ga”.
  • The relay operator will call the number you gave for you. They will tell you when the destination has been reached in some way, so do not worry about this.
  • The relay begins…
  • What you type is voiced to the person at the number you gave. (You must say ga after each message!)
  • What the person says is typed to you. (With the ga included, so please wait for the “ga”!)
  • If you want to end the relay call after a message, just type “ga or sk” instead of “ga”. “ga or sk” means “go ahead or hang up”.
  • Please allow the “hang up exchange” to happen. It is rude to abruptly hang up on the person.
  • The hang up exchange is as follows:
    • “ok well bye i gtg sk”
    • “ok bye bye sk”
    • “bye sksk”
    • “sksk” (do not type “sk” too many times, this may indicate that you are demanding to hang up right now and is rude)
    • *hang up occurs here and only here please*
  • When you have hanged up:
    • Turn off your TTY
    • Return your phone to where it was supposed to be.
