8840 TTY Telephone

[jffmsly]

I have been instructed to find information on a solution for a hearing impaired person here at work. We have an Avaya Enterprise switch with several gateways. I have found that Avaya has an 8840 telephone. I can only find sales information but no technical information on this product. My questions are:

I see that it connected with an analog connection. Is there other equipment needed to support the text-speech and speech-text feature? Or is this a stand alone product?

I would appreciate any technical information anyone could give me on this product.

This is a stand alone unit. It does NOT do text to speech or speech to text. It only does TTY to TTY
