It's a internet phone relay system for deaf people. You type in something, and the person says it over the phone.

I had fun with this and my roommates (lady on the phone typed everything I said)

BTW, they have plenty of staff, and the hold time is like 20 seconds, so I don't think we're depriving actual deaf people of this service
