I agree, to put all of it in place.... As Jon said before, it's not one single solution, so I think it's incumbent on all the carriers to actually keep looking at all of the various technologies that are out there right now. We are implementing STIR/SHAKEN. We have implemented UCB and we're actually currently evaluating other technologies that we can bolt on to these things.
There is no one quick solution that will do it, so for everything to happen, we have to keep looking at the broad selection. I do think that the smaller carriers will be able to benefit from the experience of the bigger carriers going forward, because the technology will then be applicable to them as well. It's in everybody's best interests that the entire industry is protected, so it's in our interests as well to have the small carriers included.
