TTY/TTD/TDD Trixbox Help

Good afternoon.

I know that trixbox hasn’t been updated for a while, but we are still running a distro here in our main office. I am hoping to get some help in regards to TTY/TTD/TDD.

We recently have been asked if we support this form of incoming communication. I have searched the forums, and did some google searches, and could not find anything in regards to how to enable this in asterisk/trixbox. I do show where the channel information shows a TDD MODE set to off currently.

If anyone has any information on how to enable it, how it would work, and using it, that would be great. This is all new territory for me.

Trixbox v2.8.0.4
Asterisk 1.6.0.26
