Broadband telephony

[random]

I'm trying to create a TDD (telecommunications device for the deaf) in C++ or Java (Java has a telephony API, so I'll probably end up using that), and I'm wondering if it's possible to make a call into the regular copper-wire phone system using a cable modem. I know net2phone, etc. exist, but I'd like to do this without any more expense, as my budget is $0. (Plus, the TDD standard, Baudot, is not in the audible range for humans). Can I do this? I think I used to do it to play C&C multiplayer, but I'm not sure.

Well... There's many ways you can do this...
First of all, there are 2 types... One type is just voice carried over the internet using a centralized server and a service like net2phone,many online games with voice chat, AIM voice chat, etc...(These can also be done via Internet P2P connections...)
Second, there's VoIP or Voice over IP like the service Vonage offers... It's basically a REAL telephone carried over the internet. (Basically actually their the same...)
I recommend you do it in Java with p2p connections between the 2 computers/devices, etc creating a connection...

Am I missing something or couldn't you just use a standard modem (instead of the cable modem)?

I probably should use a regular modem ... i'm going to do that anyway, but i thought it might be interesting to play /w a cable one. Speed's not important since (regular) TDDs have only 300 bps usually. I just got frustrated /w the software I'm currently using, b/c i had to have my phone modem plugged in, which i don't normally, b/c i only have one phone line (and my cable connection). Just for context/clarification, a TDD is just a phone that sends/recieves text. So it's not fast, and it's not sophisticated - i'm trying to write software that will make the computer transmit/recieve using *its* standards.

Note - if anyone wants to try using a TDD (synonym: TTY) online, go to www.relay.att.com. It's a free java-based program. You chat with a CA (communications assistant) using a TDD - emulating applet, and they speak with the person (hearing person) on the phone. Or call 711, and they'll transmit your voice in text format to a TDD number. This allows those /w TDDs to communicate with those who don't have one (hearing to deaf).
