I mean we were starting from a system that was basically e-mail, except where providers were required to deliver all messages without any discrimination or filtering. They had to create a new framework that allowed for carriers to choose not to deliver calls, interoperable technology to authenticate calls, and now close loopholes that are still allowing bad actors access to the phone network. It's a fundamental rearchitecting of how the phone network works that requires every single operator to make upgrades, so yeah it's going to take some time. And you're not really going to see much progress until it's nearly finished because if 90% of the network is secure you'll just see the same volume of crap through the remaining 10%.
