I didn't know if it would work or not, but I figured I'd try slow-speed half-duplex TDD over GSM & Vonage. I called a AGI script I have that speaks to TTYs, by calling from Vonage to one of my Voicepulse lines. I don't control the Vonage codec, so I have no idea what it uses, but I am using GSM for the Voicepulse line. Everything worked fine - echo canceling didn't cause any trouble (I don't know if it would have if I did full duplex, though), I didn't lose any characters, etc. So for people who have a need for this kind of technology, I can tell you that it will work. I'm also curious if anyone else is doing this or if anyone else is using the Asterisk TDD support. -- Joel
