You are right. As I have mentioned numerous times (I will add it to the site later), the phone number is provided by Dropio. I will move to Twilio in the near future to provide a 1800 number instead of a New York one.
In fact, most of the information you want is in the links "learn more" in the homepage, and "about this number" in the number page.
