I know that DA is free in the present iteration. What I do have a question about is procedural and will benefit everyone.
When I dial 411 and get the "National Directory Assistance" recorded lady to answer my directory request, the recording offers to connect me for an additional charge by pressing 1.
I know in the past, the telco's charged an additioal 80 cents or so for this service.

Any idea what that actual fee is? I know once you launch, some user is going to:
a. say they didn't know
b. dispute paying the charges
