Re: Docket No. WC 17-97 and CG 20-93; Ex Parte Communication

Dear Ms. Dortch:

On behalf of the AB Handshake Corporation (AB Handshake), pursuant to Section

1.1206(b)(2) of the Commission’s rules, please accept this notice of oral ex parte

communications in the above-referenced docket.

On Thursday, December 17, 2020, the two undersigned of this firm, counsel for AB

Handshake, along with Nadejda Papernaia, CEO, Vladimir Prosikhin, CSO, Sergey Okhrimenko,

CTO, and Igor Skutsenya of AB Handshake held a virtual meeting with Kenneth Carlberg of the

Commission’s Public Safety and Homeland Security Bureau and Pamela Arluk, Matthew

Collins, Connor Ferraro, Daniel Kahn, Alexander McMennamin Hobbs, and Mason Shefa of the

Commission’s Wireline Competition Bureau.

In the meeting, we discussed the Commission’s ongoing efforts to address fraudulent

robocalls and caller ID spoofing and the role of caller ID authentication frameworks in curbing

such calls. Specifically, we discussed out-of-band authentication methods that can help the

industry implement robust caller ID authentication for non-IP and mixed IP and non-IP

networks. Presentation materials that were part of the discussion are attached to this letter.

AB HANDSHAKE SOLUTIONTO ELIMINATE ROBOCALLS AND ONE-RING SCAMS

INTRODUCTION

AB Handshake actively supports FCCinitiatives to prevent spoofed calls and otherfraudulent practices.

A recent FCC report states: ”One of the mosteffective ways to prevent fraudulent activities,such as one-ring scam calls that originate inother countries, from harming Americanconsumers may be to eliminate them at theirsource.”

We believe that AB Handshake out-of-bandtechnology aligns with the FCC’s plans to stopabusive and fraudulent phone scams thatharm both American consumers andtelecommunications carriers -especially thosewho rely on personal and businesscommunication coming from outside the US

PROBLEM STATEMENT

The problem of robocalls and one-ring scamsdid not decrease significantly even with thewide adoption of STIR/SHAKEN within the USMajority of spoofed calls come from outside ofthe USA global adoption of complicated technologiesbased on digital signatures is facing seriousobstaclesBlocking robocalls by disconnecting carrierswill be damaging and affect the availability ofthe service for end users.

Works with IP and non-IP networks

Prevents Spoofed robocalls, One ring scams, CLI spoofing, Short-stopping, Call stretching, Interconnect bypass, and PBX hacking

Designed for all types of service providers: MNOs, MVNOs, Fixed line operators, Virtual PBX operators, Businesses and apps using SIP agents

Non-intrusive – no need for network upgrades and the validation process does not affect the call flow

Simple architecture – facilitates global implementation

Provides objective evidence of fraudulent call attempts to support resolution of operator disputes, payment withholding and other law enforcement needs

AB HANDSHAKE TECHNOLOGY

AB HANDSHAKE COMMUNITY

We are building a global community oftelecommunication service providers free ofrobocalls, one-ring scams and other types offraud harming the customers

The community is a perimeter of trust set up by the participants

International cooperation betweentelecommunication service providers restoresconfidence in voice services

AB HANDSHAKE OUT-OF-BAND SYSTEM ARCHITECTURE

The handshake is essentially communicationthat uses HTTPS with TLS encryption to checkfor alignment between active Call Registriesmaintained by each member of the ABHandshake community

The members of the AB Handshake community can decide whether a call that failsthe handshake validation should be blocked inreal-time, or if they only wish to receive analert while letting the call proceed

CALL VALIDATION FOR UNCONFIRMED CALL DETECTION

Unconfirmed call originates from robocall (orone-ring scam) device and is routed throughcarriers to terminating network

Terminating switch sends call data to terminating call registry to initiate callvalidation

Termination verification request is sent to callregistry on originating side

After non-discovery of this call’s details, theoriginating call registry sends an originationverification response with “no call” answer

Call registry on terminating side deduces it’san unconfirmed call scenario and sends amessage to terminating switch to alert andblock this call

SPOOFED ROBOCALL AND ONE RING SCAM DIAGRAM

DOMESTIC CALL VALIDATION FOR NON-IP NETWORKS

This diagram shows the use of AB Handshakefor calls originated from non-IP networks inthe US

Both TDM and terminating service providersuse AB Handshake call validation service

After completion of the AB Handshake callvalidation, the terminating service provider willdeliver to the end user phone a FullAttestation or its equivalent

INBOUND INTERNATIONAL CALL VALIDATION

The majority of spoofed robocalls and one ring scams are coming from abroad

Once we onboard international serviceproviders to AB Handshake, we can verify theorigin of inbound international traffic

If AB Handshake confirms that there is noinconsistency in the incoming call information,the US terminating operator passes a FullAttestation or its equivalent to the phone of acall recipient

AB HANDSHAKE GLOBAL DEVELOPMENT

We are building AB Handshake as a globalcommunity for telecom service providers

Lowering both economic and technicalbarriers to entry maximize participation bycarriers, enhancing AB Handshake’seffectiveness by increasing the number ofcalls subject to verification

We are initially targeting jurisdictions mostcommonly associated with fraud : This strategy will provide significant value

to telecommunication service providersand consumers in the US

It is also valuable for telecom serviceproviders located in jurisdictionsassociated with fraud because ABHandshake allows to confirm legitimatecalls originated in those jurisdictions
