Internet Phone Call site...?

A while back I used to have a website which you could make a phone call from. You could call anywhere in the US, for free. You would type and the computer would talk to the other person (and their voice would in turn become written words to you).

When I updated my AOL version I lost it from my favorite places. Has anyone ever seen this website (or one like it) before? I want to get my hands back on the URL, and I can’t see mto find it anywhere! Any help would be great, thanks!

PS. I know that the site was made so that people who were hearing disabled could make phone calls, but the service is free to anyone who can find it. Just thought I’d add that in.
