If you're absolutely asking about Voice Over IP (VOIP) telephone systems like Vonage, then MAYBE you can use a TTY over them.
It should work - but you may have problems occasionally missing characters. It's a problem the the VOIP people have identified and are working on fixing. If you want to switch over, go ahead, but check with the company first to get a GUARANTEE in WRITING that TTYs will work.
Dennis said:NexTalk isn't VOIP. There's a long answer in the difference between VOIP and NexTalk. Hope you have the patience to read it.
There are two different kinds of NexTalk:
1) NexTalk-VM (voice modem): It's a phone program that uses your home phone line hooked up to your computer modem, NOT your broadband (DSL or Cable Internet) to make and receive TTY calls. You make the TTY tone in your own computer modem to send over the telephone line to your friend's TTY.
2) NexTalk.net (web browser): It's an internet program that connects to a SERVER with a bank of voice modems to make TTY calls from a central location. You transmit information between the server and your computer using standard ASCII text, NOT VOIP protocol. The server recognizes that you're sending the letter "e" then creates the TTY tone in the voice modem to send over the telephone line.
The advantage of this is that less infromation is transmitted between the computers, and it's less error prone. But, you can't use your voice because your voice doesn't transmit in text.
VOIP protocol:
VOIP protocol would be like you sending the actual TTY tones over the internet. So far, we've only transmitted the tones over our own phone line (#1), OR sent plain text to a company's server which will then transmit the tones over the server's phone lines (#2).
VOIP has some problems doing the TTY tones. Some companies can't even do it AT ALL. Why? It's hard to explain unless you're familiar with network packets and how computers sample TTY tones, but the result is, YOU END UP MISSING CHARACTERS. You may not even know that you're missing them, but voice users don't have this problem, so it's NOT equal access.
However, the advantage to using VOIP is, THEORETICALLY, you could use voice and text at the same time (voice carry over, or VCO) because VOIP should be able to do both equally well.
Helpful?
justlook said:voip wont do or work with 911 as you have seen other thread or news about it....better off keep landline without long discont call unless you have direct emgecy call number. in future they are work on "e-911" which can track down within 3-5 miles or 150 foot (?) radus. it s long way go to made final have something without landline..
ideafspy said:About the 911; the VoIP can to do with 911 but it will be
specific where you are once you sign up the account. Suppose, you took the telephone to friend house and using their high speed access. The phone will rang anywhere you are at. Suppose, you are dialing 911 in Florida while you live in Texas. The police or whatever will direct to Texas and not Florida.
Speaking about 911, I am not sure if this forum have talk about 911 across the internet? Some people believe that VP should handle with 911. It might sound strange but will that going happen?
diehardbiker65 said:911 over VP? Not now, BUT EVENTUALLY it will happen. Just that it takes time for somebody to figure out HOW, or invent something that is WORKABLE with 911 system.
5 years ago, it is IMPOSSIBLE to track down 911 calls with cell phone. Now somebody came up with brilliant idea how to make this work. So, I can bet my ass that it will happen with VP.
qwerty123 said:Yes, NOW, 911 over VOIP will work as long as you sign up with the VOIP provider.
http://www.vonage.com/features.php?feature=911
Not all VOIP providers have working 911 system so hope in the near future all of them should have 911 infor. IT is very important that each VOIP subscriber sign up with their provider and keep the address current in their database.
ideafspy said:I don't if VOIP is right word, anyway; it that line able to use tty? I am just curious about that one.![]()
So I decied to go ahead and try it out for Vonage to see if I like it or not.Neo said:and I dont need TTY. I use aim for relay and just dial 911 for help and no need talk just let it track me.
Why need TTY for?
for VP!Dennis said:There aren't any 911 services just for TTY, but all emergency centers should be equipped because they will deal with all sorts of callers. Many underfunded places may not have them or aren't trained in them, though. The best thing to do is to just call 911 and type as much as you can and hope they have the equipment and training to understand you, or else they'll at least track you down and make a visit to your home.
deafunix said:For deaf friends who don't have VP. Soon the TTY will be gone 'bye bye'.for VP!
What kind of relay service you have for 911? Any? The FCC said you have to use TTY directly. The faster to track to the caller's location, the sooner they arrives for help before your parent dies or whoever.
About TTY with VOIP. You have to know the speed rate of bauds to avoid packets loss or delay of milliseconds. Then adjust it in the similar speed and it's works for me.
Pomeranian said:Yea make a visit to my home. I remmy one time my stepson was playing a game by dialing 911 and the cop came to my house. I was like HUH!!! GRRRRRRRRR so I told him to stop. Then it never happened again.
As for TTY yea kissed it goodbye. When making a long distance call thru tty is tooooooooooo much money. I still have a landline since I need it for 911. I just wish I have a way to get 911 thru my cellphone so I can kissed my landline.
