Guaranteed Caller International

The Challenge

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.
