Help stop robocalls and nuisance calls internationally

Communications Service Providers (CSPs), enterprises, equipment manufacturers and industry standards bodies across the globe can join the Global Trust Lab and participate in a testbed to validate industry standards that help restore trust to the phone channel.

Current Testbeds

Brazil
Canada
United States

In North America, testing is conducted as part of the ATIS Robocalling Testbed, which is exclusively hosted by TransUnion. The goal of the ATIS Robocalling Testbed is to remove obstacles and accelerate the validation of caller authentication standards like STIR/SHAKEN. TransUnion provides technical support for the relevant connectivity information, representative network configuration, our Caller ID Authentication software functionality and supported test scenarios. Visit the ATIS Testbed site here.

Upcoming developments

With stable, interoperable and compliant STIR/SHAKEN call authentication solutions now operating within multiple countries, there’s growing interest in various new developments, including:

Cross-border call authentication: Advances are being made in deploying trusted and interoperable cross-border STIR/SHAKEN call authentication across countries. The most recent approach is described in ATIS-1000087.v002.

Diverted call authentication: Advances are being made in the ability to authenticate diverted calls (e.g., forwarded calls) that are susceptible to malicious replay attacks. A new PASSporT type (“div”), based on IETF standards, is detailed in ATIS-1000085.v002, while details about the signing and verification RESTful API requirements to support “div” are in 3GPP TS 24.229.

Delegate certificates: While participation in STIR/SHAKEN today is tightly governed, certain entities may be better positioned to indicate their authorized use of a calling telephone number by signing their own calls. (See ATIS-1000092.)

See also ATIS-1000094 to learn about our Rich Call Data (RCD) standard.

The Global Trust Lab is well positioned to help accelerate industry adoption of these and other extensions.
