Guaranteed Caller Enterprise

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 Enterprises, it might be difficult to obtain A-level attestation because the Originating Service Provider doesn’t necessarily have all the information to offer such an attestation. Enterprises often purchase Telephone Numbers (TNs) from a source, then load-balance their outgoing calls over multiple voice service providers, hence the correlation of the TNs with the Enterprise is not always apparent. 

The NetNumber Solution

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™ Enterprise is using authorization delegated from the Service Provider level to sign and verify calls from Enterprises to their service providers. Guaranteed Caller™ Enterprise allows service providers to monetize STIR/SHAKEN immediately. It includes Enterprise Onboarding/Vetting Service, Subordinate-CA Service, Delegate Certificate Management, RCD PASSPorT call signing and full resale/wholesale capability.

Key Features

IETF/ATIS Compliant
The Guaranteed Caller™ family is fully compliant with all relevant IETF/ATIS standards for STIR/SHAKEN.


FIPS 140-2 Level 1, Level 2 Compliant
All key-related elements of Guaranteed Caller™ are FIPS 140-2 Level 1 compliant. Level 2 compliance is an available option.


Fully Cloud Native, Containerized Implementation
Guaranteed Caller™ is fully cloud native and containerized, providing effectively unlimited capacity via a highly elastic dynamic scaling capability.


Support for TDM-SHAKEN
Guaranteed Caller™ Service Provider includes full support for TDM-SHAKEN. The in-network Cloud Connect node optionally supports TDM/SS7 physical interfaces.


Configurable Selection of Calls to be Signed
Not all calls need to be signed to be known free from CLI spoofing. Unnecessary call signing may equate to unnecessary OPEX. The Guaranteed Caller™ in-network Cloud Connect node provides configurable call signing selection rules, saving service providers unnecessary spend by selecting for signature only those calls that need to be signed.


Configurable Call Attestation Rules
STIR/SHAKEN relies on accurate call attestation. The Guaranteed Caller™ in-network Cloud Connect node provides configurable rules for setting attestation levels, ensuring that this critical value is set in compliance with local network policy.


Configurable OrigID Values
The STIR/SHAKEN OrigID value supports traceback of calls that incorrectly received an “A” attestation. The Guaranteed Caller™ in-network Cloud Connect node provides configurable rules for setting OrigID as local network policy dictates.
