Thank you for the question. I'll try not to use up all of your time.
We're doing as much as we can. It is truly a terrible problem. We have agreements with the FCC and the Australian regulator and others, such as memoranda of understanding, to work together to try to address it.
Some of the measures that we've taken include blocking calls at source. For what are called malformed numbers—things that are obviously not real numbers—we've authorized the carriers to block those at source. We've introduced a system called Stir/Shaken, which, as it's applied, will allow companies to indicate to consumers whether or not the call has been verified. We've also recently approved what was a trial to use artificial intelligence to identify and screen out some of these calls.
I do have to quickly add that a couple of years ago when I looked at the numbers, we were talking about numbers that were something like 200,000 calls per second in the United States.
