what exactly is tty? i have it on my phone but i never can figure it out....help me please.
Are you talking about a cell phone that has "TTY" - if so, it means that it is compatible with a portable TTY (you plug it into the headphone jack). You have to have a separate portable TTY though - you can't just set it to "TTY mode" and then place a call directly to another TTY user that way.
If you mean a landline phone - the only "dual phone/TTY" I know of is the Uniphone 1140. It is a single phone that is a "regular phone" (for hearing people), amplified phone (for Hoh & CI deaf) and a TTY (with VCO and HCO capabilities)
If you live in the USA - you are also able to use IP relay ... which is a relay service that allows you to go to any of the specific IP relay websites (ip relay, sprint, AT&T, Purple etc) and then on their site they will have a "place a relay call" button/link ... You are then able to place and outgoing text relay call from your computer (to a hearing person) on their secure website. Each of the IP Relay sites will have a "how to use IP Relay" demo that will walk you through how the system works. If you've never used the system before - when you connect to the relay operator , you can tell them that it's your first time using IP relay (or relay, period) and they will help you through the call.
If you live in Canada or the USA and have a computer with a decent internet connection, &/or have a smart phone blackberry, iPhone, etc) with Instant messaging programs (AIM,MSN or Yahoo) you can use Messenger Relay Service (MRS) - In the USA Messenger Relay Services are a component of IP relay (so the details for using the MRS service will be on the IP relay site ie: Sprint, IP Relay, i711, AT&T etc). In Canada the only Messenger Relay Service we have is via Rogers - so go to the Rogers.ca website then under "Special Needs" you'll find the details of the MRS service)
MRS allows you to contact a Relay Service though a few different instant messenger programs (AIM, MSN, Yahoo) . To get started - in the USA go to your preferred IP relay website and look under the IM relay section for the detail about adding them to your IM program of choice. In Canada, go to the Rogers.ca website for details (under special needs, then Relay/ Messenger Relay) ... once you have the various Relay ID/username/email info etc ... then you simply add that name/email to your IM contact/buddy list.
When you want to place a call - just click on that contact/buddy and then say "Hello" (when an operator is availabel they will prompt you for your contact info and then info of the caller you are wanting to call.
From there it basically works just like a traditional TTY relay call - except that the use of "GA" isn't technically needed (though it is helpful, so many of use still use it).
In case you're not familiar with how relay works ....
basically you just type what you want to say to the caller (hearing person who's cell/landline you asked to be connected to) and the relay operator will voice the text for you. To let the person on the other side (hearing person) a chance to speak or let them know you are waiting for them to say something/answer a question, you just type "GA" (short of go ahead - which is the "cue" that you're now waiting for them to say something).
When the hearing person responds the relay operator will then type whatever is said, and when the hearing person pauses (is waiting for you to respond they will type "ga" (go ahead, ie they are waiting for you to say something). This goes back and forth for the either conversation - With IM you can also see if the other person is typing ... so it's easier to avoid "Talking on top of each other", or one person "Stuck" and unable to interject if needed - which sometimes happens in TTY relay.
When you're finished with the call - you simply say your good-byes with the other person and then type "ga or SK" (which means "Go Ahead or stop keying" aka - do you have anything else to say or are you ready to "stop keying" and "hang up". If they're done you'll see "sk" or "sksk" (both of which mean "hanging up") to which you reply "sksk" which tells the relay operator that they should hang up.
It has it's "hiccups" but for the most part it works very well
There is also a video based Relay called "VRS" which uses a high speed internet connection either on your TV or directly on your computer - VRS is for people who prefer to use ASL (sign language) to communicate instead of typing in English. Because VRS uses Sign Language the relay operators are ASL/English interpreters - just like the skill of text based relay operators varies ... so does the quality of VRS interpreters (which is why many people pick the VRS company they find "best" for them and then use it almost exclusively)
