Is the Federal Trade Commission (FTC) list of telemarketer phone numbers that have received complaints available? Supposedly Nomorobo has access to it, but I believe that is as a result of having won the FTC's Robocall Challenge. However, can users of FREESwitch also use this list?
More generally, are there web services (free or paid) that supply a feed of a list (or diff of the list for updates) of these numbers via a web service API?
