www.bekabusinessmedia.com SHOW.INCOMPAS.ORG 11 DAY 2 Branded Calling ID Services: An Overview from TransNexus In yesterday’s INCOMPAS Show Daily, we provided an introduction to Branded Calling ID. Today, we will continue the discussion with a brief overview of how it works and the key differences from proprietary branded calling solutions. BCID and Rich Call Data Branded Calling ID (BCID) uses a nonproprietary, standards-based approach to deliver branded calling information. It’s called Rich Call Data (RCD), and it builds upon the STIR/ SHAKEN call authentication standards. In STIR/SHAKEN, authenticated caller information is put into a SHAKEN PASSporT, which is then cryptographically signed using Public Key Infrastructure techniques to create a trusted signature. The terminating provider verifies the signature. These techniques ensure that information in the PASSporT cannot be changed or replayed. Rich Call Data provides a standardized method of adding information about the caller to the PASSporT, where the cryptographic techniques ensure that it won’t be altered. Here’s an example of the payload in a SHAKEN PASSporT: “attest”:”A”, “crn”:” Upcoming Delivery” “dest”:{“tn”:[“12025551001”]}, “iat”:1443208345, “orig”:{“tn”:”12025551000”}, “origid”:”123e4567-e89b-12d3a456-426655440000”, “rcd”:{ “icn”: “https://example.com/photos/acmedelivery-logo-256x256.png” “nam”:”ACME Delivery Service” } “rcdi”: { “/icn”: “sha256-RojgWwU6xUtI4q82+kHPyHm1 JKbm7+663bMvzymhkl4” } This SHAKEN PASSporT provides information for a call from 1-202-555-1000 to 1-202-555-1001 with a full A-level attestation. The IAT claim is the time-date stamp, and the OrigId is an optional identifier. The CRN provides a call reason, in this case, “Upcoming Delivery.” This is an optional feature in branded calling. The RCD section includes an ICN, which is the URL of the caller’s logo. This is also optional. The RCDI section provides an integrity value generated to ensure that the image posted at that link hasn’t changed since this PASSporT was authenticated. The RCD name conveys the brand name in branded calling. This is the bare minimum information presented in branded calling. Per the standards, it should only be used on calls that qualify for a full A-level attestation. BCID versus Proprietary Branded Calling BCID differs from the current proprietary branded calling solutions in several key areas: 1. BCID uses the Rich Call Data standards developed for STIR/SHAKEN to communicate branded call information, rather than proprietary out-of-band networks. 2. Branded calling information is independently vetted and verified by authorized partners, rather than the same business that sold a proprietary branded calling service. 3. BCID ensures network interoperability through a single uniform end-to-end ecosystem, avoiding the complexities of sharing branded calling information and activity across multiple proprietary networks. 4. Unlike proprietary solutions, BCID provides callers with a confirmation that their brand information was delivered. p TransNexus offers software for telecom service providers to manage and protect their telecom networks, including STIR/SHAKEN.
