I have a Captel phone, but hardly ever use it mainly because my family takes care of phone calls or I use the Internet relay service without voice carry over (VCO). I prefer using my computer for calls since I can keep a record of the call — something the Captel phone doesn’t have.
Now Sprint makes it possible to make relay calls over the Internet AND use VCO. I read about a way to do this a long time ago, but it was very confusing and required messing with the phone set up. But not this time.
Already found one drawback, I can’t call someone in Toronto or Ontario. It just happened that the first call I tried was to Ontario (I didn’t realize the person was in Canada from the area code). Nonetheless, Sprint impresses me with all the tools, services, and prices available for the deaf. I’ve worked for two major telecommunications companies and neither were Sprint.
