Robocalling Blocking Cause and Effect

Robocalls - State of industry Robocalling, spamming, scamming, spoofing are scenarios that play out for consumers multiple times a week. 28.5 Billion US only number of robocall received 2018 FCC has received 3.7 million complaints in 2018 In the past year more than 740,000 Canadians have complained to the Canadian Anti-Fraud Centre about being targeted by a phone scam The CRTC receives more complaints about nuisance communications—specifically, spam and telemarketing than any other subject.

Robocalls - State of industry Unregulated call blocking and labeling solution providers are making the decisions on how to present legal enterprise calls to the consumer There are technologies to identify and block illegal robocalls, but they are getting it wrong in the U.S.

STIR/SHAKEN STIR: Secure Telephone Identity Revisited - defines a signature to verify the calling number, and specifies how it will be transported in SIP “on the wire”. SHAKEN: Signature-based Handling of Asserted information using toKENs - the framework document developed to provide an implementation profile for Service Providers implementing STIR. Together, STIR and SHAKEN represent the SIP protocol changes, signature standard, and interoperability framework.

Benefits & Limitations Consumers will have more information when deciding whether to answer a call. The identity of the originating carrier is included with the call authentication information. Knowing the originating carrier will accelerate illegal robocall tracebacks and enforcement. Limitations It can only identify if a call was not spoofed – not whether or not the caller is a scammer. It only works on an IP end-to-end call path. The benefits will not fully materialize until all service providers implement the STIR/SHAKEN standards

Analytics Server STIR/SHAKEN will provide crucial layer of protection, however, consensus is clear: a layered approach requiring access to an Analytics Server at the Verification point is also required.

Presented by Marian Hearn – ATIS - The SHAKEN Governance Model Webinar Canadian STIR/SHAKEN January 2018 the CRTC Compliance and Enforcement Sector issued CRTC 2018-32, “Measures to reduce caller identification spoofing and to determine the origins of nuisance calls”. That decision directed the Canadian telecom industry to: Develop a traceback process at the CISC Network and Technical Working Group(NTWG), Report on the status of the industry readiness for “authentication and verification of caller ID information for IP voice calls” using STIR/SHAKEN, through NTWG Establish a governance framework Presented by Marian Hearn – ATIS - The SHAKEN Governance Model Webinar

Presented by Marian Hearn – ATIS - The SHAKEN Governance Model Webinar Canadian STIR/SHAKEN A small group of carriers have incorporated the CSTGA to fulfill the role of GA, based on the governance model in ATIS-1000080. The detailed corporate structure continues to be a work in progress. A technical advisory committee (TC) was established and has produced a Canadian technical requirements document (CTRD) for SHAKEN governance. TC is evaluating technical and operational issues relating to the PA and CA roles, including exchange of international certificates, beginning with Canada/U.S. Informal discussions are ongoing with a number of vendors who are interested in fulfilling the role of PA for Canada. There is ongoing dialogue with CRTC staff regarding formal endorsement of the CSTGA as the Canadian GA. Presented by Marian Hearn – ATIS - The SHAKEN Governance Model Webinar
