American consumers receive over 200K unwanted and/or fraudulent calls every minute, many using spoofed caller IDs to increase the likelihood that the called party will answer the call. Both the FCC in the USA, through the TRACED Act and the CRTC in Canada, have mandated service provider implementation of the STIR/SHAKEN set of standards as a solution to the widespread use of CLI spoofing in fraudulent calls.
For international carriers, it might be difficult to obtain A-level attestation because they are not part of the STIR/SHAKEN ecosystem in the United States or Canada. Their interconnect partner in the US or Canada often doesn’t have the knowledge of the CLI association with the international carrier’s subscriber to help with A-level attestation either.
Guaranteed Caller™ is NetNumber’s family of STIR/SHAKEN solutions, providing proactive and IETF/ATIS compliant CLI validation solutions for all common calling scenarios.
Guaranteed Caller™ International is using authorization delegated from the Service Provider level to sign and verify calls originating in a
service provider network outside the USA/Canada. Guaranteed Caller™ International provides global carriers with improved call answer rates while simultaneously providing an important competitive differentiator.
