Sam understands it all very well.
I agree with both you and Ms. Hancock that the LECs don't want it to be easy.
I do disagree that it takes much research, though, to determine one's local calling area, at least in California and a few other states that I am familiar with that have all local office codes that are local clearly listed in the front of the phone book.
Then again, some of today's consumers can't find Mexico on a world map. ;-)
As to extended calling plans that some folks may have, that is irrelevant when selecting a primary or virtual number for Vonage. Why make it more complicated than it has to be?
Vonage makes it easy, really easy.
