Teleblock can do for carriers what OnStar has done for cars.
If you are buying a new car and you can get comparable cars at comparable prices but one has OnStar and the other doesn't, which would you choose?
If you are a (legit) telemarketer, which carrier are you going to use, one with Teleblock or one without?
It looks like carriers may be jumping on the recent FTC fines as an opportunity to get compliant at their level and then use that capability to sell to end users. Hopefully COPI is setting up carriers at low or no cost to help get the revenue machine in place.
