We have developed a global call validation solution that solves this issue — AB Handshake. It can eliminate many fraud types such as IRSF ($5B), CLI spoofing ($2B), short stopping & call stretching ($4B), interconnect bypass ($2.7B), PBX hacking ($3.6B), robocalls ($0.9B) + wangiri, wangiri 2.0 and others ($9.8B).
We welcome all telecom professionals to join and validate calls on a global scale.
Here's how it works: using special software and hardware, AB Handshake connects originating and terminating operators and makes it possible to exchange call details in real-time and compare the results to check if the call took place, was terminated to the end user and was received from the original number of the caller.
Join the AB Handshake framework now and become a part of telecom history!
