Using Watch to reduce illegal robocall traffic

Three service providers cut illegal and unlawful traffic and kept growing

A wholesale intermediary, a large CPaaS, and a smaller CPaaS used Watch on traffic originating or crossing their networks. Illegal robocall volume fell at all three, even though each already had Know Your Customer programs in place. All three still use it to successfully keep illegal traffic to a minimum, while continuing to grow their businesses.
