“Imagine the difference if every A-party was matched to every B-party, with no spoofing, manipulation or short-stopping. This simple fix would end most robocalls, make refiling impossible, stop simboxing, kill wangiri and make it easy to tackle international revenue share fraud. Delivering absolute certainty about the origin and destination of each call is the goal that motivates the AB Handshake, and the telcos who join it. Their objective is simple, realistic, and attainable.”.
