Guaranteed Caller® Service Provider

The Challenge

American consumers receive over 200,000 unwanted and/or fraudulent calls every minute, many of which use spoofed caller IDs to increase the likelihood that the called party will answer. Both the FCC in the USA — through the TRACED Act — and the CRTC in Canada have mandated that service providers implement the STIR/SHAKEN set of standards as a solution to the widespread use of caller ID spoofing in fraudulent calls.

The netnumber Global Data Services Solution

Guaranteed Caller® is our family of STIR/SHAKEN solutions, providing proactive and IETF/ATIS-compliant caller ID validation solutions for all common calling scenarios. 

Guaranteed Caller® Service Provider uses credentials and certificates from the national level to sign and verify consumer calls within an operator network. It fully meets all current FCC/CRTC mandates for IP STIR/SHAKEN standards, and it includes STI-AS, STI-VS (with included CRc certificate cache), SP-KMS, SKS and STI-CR. An optional CVT capability is available.

Guaranteed Caller® Service Provider provides three unique functional sets:

  • Service Provider Certificate Management (SPCM) generates new public/private key sets on a regular basis and then interacts with the STI-CA to request and receive STI-CA signed certificates. SPCM requests fixed-duration certificates that have a minimum lifetime of 24 hours and a maximum lifetime of 365 days. Signed certificates received from the STI-CA are pushed to the Guaranteed Caller® STI-CR. The associated private key is pushed to the Guaranteed Caller® SKS. At the end of their lifetime, certificates are automatically refreshed by SPCM until Guaranteed Caller® Service Provider service is canceled by the service provider.
  • Service Provider Call Signing (SPCS) is used to sign calls on behalf of customers. Access SPCS is via the ATIS 1000082 HTTPS/JSON API (or other technically feasible API approved by netnumber Global Data Services, including SIP Redirect) using a netnumber-generated security token and/or customer-sourced IP address(es). API queries received by SPCS with a valid authorization receive back a cryptographically signed SHAKEN PASSporT.
  • Service Provider Signature Verification (SPSV) is used to verify call signatures on behalf of customers. Access to SPSV is via the ATIS 1000082 HTTPS/JSON API (or other technically feasible API approved by netnumber Global Data Services, including SIP Redirect) using a netnumber-generated security token and/or customer-sourced IP address(es). API queries received by SPSV include a valid authorization and a cryptographically signed SHAKEN PASSporT. Received SHAKEN PASSporTs are verified by SPSV, and the results of that verification are returned via the ATIS 1000082 HTTPS/JSON API to the query source.

Key Features

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

Guaranteed Caller® is fully cloud native and containerized, providing effectively unlimited capacity via a highly elastic and dynamic scaling capability.

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

Not all calls need to be signed to be free from caller ID 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 only selecting calls that need to be signed.

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.

The STIR/SHAKEN OrigID value supports the 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.

Benefits

  • Fully comply with FCC and CRTC mandates for STIR/SHAKEN
  • Increase customer satisfaction by ending fraudulent caller ID spoofing
  • Minimize spend to implement STIR/SHAKEN in the network
  • Minimize network impact from STIR/SHAKEN compliance
  • Control CAPEX expenditure necessary to comply
