There is a vast gap between assembling a few "this is what I did" posts from Google etc and being able to make them work.

Examples are too many to count.. The desired result is- emulating POTS to the user. They pick up phone- get tone- dial- finish call and hang up. It just plain works. Details in progress- but one example would be perhaps setting up a "softphone" demo for ITEC. An unlimited calls per month Skype account is <$5 a month for the rest of the story. I do wonder in the real world if a seven port powered USB hub would handle a few such phones?
