Audit with IP address tracing. Its a lot of work for FCC. There is not a single reason behind this But bottom line, it is all about money that is all. (INCORRECT)
One CEO as we know it cheated and busted all the way down to the floor where there are average workers trying to help company by cheating, or get away from their duties got busted as well. So, if CEO bust of any wrongdoing, they are criminally responsible, for example John Yeh we all know, but if an employee got busted, Company STILL responsible but only by financially but not criminally. What disgusted me is that the consequence of any VRS employee caught cheating was just terminate from employment and barred from working for any VRS companies. They were not criminally punished.
What QWERTY123 said recently is correct.
I am not sure what the best way to prevent the fraud from happening again because the way the business runs, it is very complicated (CORRECT) and it is not just a simple system where terp takes a call from hearing or Deaf and get connect with other parties and when its done, that is not what is really happened.
BUT, we could minimize the fraud and I don't think up to 100%, the proposal that Z made to FCC is not best way to handle fraud billing. It also chokes competitions to the point where it is just "one size fits all" will ultimate downgrade the QOS (Quality Of Service).
In order to be able to keep fraud to minimize, we need to have FCC deal with IANA to register about 100 ports that is reserved for VRS and VP so that it is easier to audit and bust for any irregularities and to lock out the hackers.
