I just discovered that there is no 411 service on AT&T\’s CallVantage service. You can only do lookups via their Anywho.com service or obviously any other online directory of your choosing. Kind of a strange piece to leave out if you ask me. I don\’t call 411 too often, but just tried and found out it does not work. After a call into customer support, I discovered it\’s not offered at all.
