Download as PDF 53705 Federal Register / Vol. 87, No. 169 / Thursday, September 1, 2022 / Proposed Rules IX. Statutory and Executive Order Reviews Under the Clean Air Act (CAA), the Administrator is required to approve a SIP submission that complies with the provisions of the Act and applicable Federal regulations. 42 U.S.C. 7410(k); 40 CFR 52.02(a). Thus, in reviewing SIP submissions, the EPA’s role is to approve state choices, provided that they meet the criteria of the CAA. Accordingly, this action merely approves state law as meeting Federal requirements and does not impose additional requirements beyond those imposed by state law. For that reason, this action: • Is not a significant regulatory action subject to review by the Office of Management and Budget under Executive Orders 12866 (58 FR 51735, October 4, 1993) and 13563 (76 FR 3821, January 21, 2011); • Does not impose an information collection burden under the provisions of the Paperwork Reduction Act (44 U.S.C. 3501 et seq.); • Is certified as not having a significant economic impact on a substantial number of small entities under the Regulatory Flexibility Act (5 U.S.C. 601 et seq.); • Does not contain any unfunded mandate or significantly or uniquely affect small governments, as described in the Unfunded Mandates Reform Act of 1995 (Pub. L. 104–4); • Does not have federalism implications as specified in Executive Order 13132 (64 FR 43255, August 10, 1999); • Is not an economically significant regulatory action based on health or safety risks subject to Executive Order 13045 (62 FR 19885, April 23, 1997); • Is not a significant regulatory action subject to Executive Order 13211 (66 FR 28355, May 22, 2001); • Is not subject to requirements of the National Technology Transfer and Advancement Act (NTTA) because this rulemaking does not involve technical standards; and • This action does not have disproportionately high and adverse human health or environmental effects on minority populations, low-income populations and/or indigenous peoples, as specified in Executive Order 12898 (59 FR 7629, February 16, 1994). The basis for this determination is contained in section VII of this action, ‘‘Environmental Justice Concerns.’’ The SIP is not approved to apply on any Indian reservation land or in any other area where the EPA or an Indian tribe has demonstrated that a tribe has jurisdiction. In those areas of Indian country, the proposed rule does not have tribal implications and will not impose substantial direct costs on tribal governments or preempt tribal law as specified by Executive Order 13175 (65 FR 67249, November 9, 2000).

Synopsis I. Comments Sought on STIR/SHAKEN Implementation Extensions for Annual Review, Pursuant to Section 4(b)(5) of the TRACED Act When Congress directed the Commission to mandate implementation of STIR/SHAKEN in the TRACED Act, it also required the Commission to assess burdens and barriers to implementation, and it gave the Commission discretion to extend compliance with the implementation mandate upon a public finding of undue hardship. The Commission performed this assessment and granted three categorical extensions of the STIR/ SHAKEN mandate on the basis of undue hardship: (1) small voice service providers; (2) voice service providers unable to obtain the ‘‘token’’ necessary to participate in STIR/SHAKEN; and (3) services scheduled for section 214 PO 00000 Frm 00008 Fmt 4702 Sfmt 4702 discontinuance. See Second Caller ID Authentication Report and Order, 85 FR 73360 (Nov. 17, 2020). (As directed by a separate provision of the TRACED Act, TRACED Act § 4(b)(5)(B), the Commission also granted an extension for those portions of the network that rely on technology that cannot initiate, maintain, and terminate SIP calls. Because this extension was not granted on the basis of undue hardship, we do not seek comment on it in this Public Notice.) The TRACED Act further requires the Commission to assess burdens and barriers to implementation ‘‘as appropriate’’ after that initial assessment, and directs the Commission to, ‘‘not less frequently than annually after the first [extension] is granted,’’ reevaluate and potentially revise any extensions granted on the basis of undue hardship. It requires the Commission to issue a public notice explaining ‘‘why such [extension] remains necessary’’ and ‘‘when the Commission expects to achieve the goal of full participation’’ in caller ID authentication. To comply with these obligations, the Commission directed the Bureau in the Second Caller ID Authentication Report and Order to annually reevaluate the Commission’s granted extensions for undue hardship and revise or extend those extensions as necessary. (The Commission determined that the Bureau is in the best position to undertake this fact-intensive, case-bycase evaluation.) In its directions to the Bureau, the Commission permitted the Bureau to further extend an extension to which voice service providers are already subject, but prohibited the Bureau from terminating an extension prior to the extension’s originally set end date. The Commission did not permit the Bureau to grant extensions to any voice service providers or services not already subject to one. Should we further extend a granted extension, we are permitted to decrease, but not expand, the scope of entities entitled to that extension based on our assessment of burdens and barriers. In September 2021, we released a Public Notice seeking comment on the Commission’s three granted extensions and any associated burdens and barriers to the implementation of STIR/ SHAKEN. 86 FR 56705 (Oct. 12, 2021). In December 2021, we issued our first annual reevaluation and declined to modify any of the existing extensions. The extension for services scheduled for section 214 discontinuance ended on June 30, 2022. We now seek comment to enable our second annual reevaluation of the two remaining STIR/ SHAKEN implementation extensions— E:\FR\FM\01SEP1.SGM 01SEP1 jspears on DSK121TN23PROD with PROPOSALS Federal Register / Vol. 87, No. 169 / Thursday, September 1, 2022 / Proposed Rules for small voice service providers and for providers unable to obtain the required token—granted based on undue hardship. Small Voice Service Provider Extension. We seek comment on the Commission’s extension for facilitiesbased small voice service providers. In September 2020, the Commission granted a two-year extension for all small voice service providers, defined as ‘‘a provider that has 100,000 or fewer voice service subscriber lines.’’ Second Caller ID Authentication Report and Order. Under this extension, small voice service providers were given until June 30, 2023 to implement STIR/SHAKEN. The Commission found that this extension was appropriate because small voice service providers may face substantial costs—in addition to resource constraints—to implement STIR/SHAKEN and confront unique equipment availability issues. In December 2021, the Commission shortened the extension for a subset of small voice service providers likely to be the source of illegal robocalls. 87 FR 3684 (Jan. 25, 2022) It shortened the extension to one year—until June 30, 2022—for non-facilities-based small voice service providers based on overwhelming record support and available evidence showing that this subset of providers were originating a large and disproportionate amount of robocalls. It also required small voice service providers suspected of originating illegal robocalls to implement STIR/SHAKEN on an accelerated timeline. The Commission maintained the two-year extension for facilities-based small voice service providers because it found they were less likely to be the source of illegal robocalls. When we considered this remaining extension in the 2021 annual reevaluation, we declined to lengthen it beyond June 30, 2023, noting that the Commission’s guiding principle in establishing the extension was ‘‘to achieve ubiquitous STIR/SHAKEN implementation to combat the scourge of illegal caller ID spoofing as quickly as possible.’’ We seek comment on the burdens and barriers to facilities-based small voice service provider implementation and whether we should revise their STIR/ SHAKEN extension. Have the burdens or barriers affecting small providers originally discussed in the Second Caller ID Authentication Report and Order, changed since last year’s evaluation and, if so, how? Should any Commission actions in the previous year inform or impact our reevaluation of the small voice service provider extension? Have any new burdens or VerDate Sep<11>2014 16:46 Aug 31, 2022 Jkt 256001 barriers emerged that the Commission did not consider or could not have been aware of when it initially gave small voice service providers a two-year extension? If so, do these burdens or barriers warrant an extension beyond the current June 30, 2023 date, and if so, how long of an extension is necessary and appropriate? How would any additional extension be consistent with the Commission’s goal of ubiquitous STIR/SHAKEN implementation? In response to our Public Notice seeking comment for the 2021 annual extension reevaluation, the Satellite Industry Association (SIA) requested an ‘‘indefinite’’ extension for satellite voice service providers’’ in light of the ‘‘challenging circumstances facing small satellite VSPs, combined with their unique economic, operational, and technical characteristics.’’ The Bureau determined that the record was insufficient to evaluate SIA’s request at that time, but stated it would seek further comment on the request as part of the instant 2022 reevaluation. In the interim, as part of its May 2022 Further Notice of Proposed Rulemaking, 87 FR 42670 (July 18, 2022), the Commission sought comment on the larger questions of the applicability of the TRACED Act to small satellite providers and whether it should grant such providers an extension for implementing STIR/ SHAKEN. Should the Bureau further extend the small provider implementation extension just for small satellite voice service providers as part of this inquiry or should we leave this issue to the full Commission to consider more generally? Do small satellite voice service providers face unique challenges in implementing STIR/SHAKEN? What are these challenges? How do they impact this subset of providers’ ability to implement STIR/SHAKEN? What is a realistic time frame for any extension we grant? What impact would an extension for small satellite voice service providers have on other providers or the public? What impact would such an extension have on the Commission’s longstanding goal of ubiquitous deployment of STIR/ SHAKEN? Extension for Voice Service Providers That Cannot Obtain a SPC Token. We seek comment on the Commission’s extension for voice service providers that cannot obtain the Service Provider Code (SPC) token necessary to participate in STIR/SHAKEN. In the Second Caller ID Authentication Report and Order, the Commission granted voice service providers that are incapable of obtaining a SPC token due to Governance Authority policy an PO 00000 Frm 00009 Fmt 4702 Sfmt 4702 53707 extension until they are capable of obtaining said token. (Recognizing that ‘‘a voice service provider may not be able to immediately come into compliance with its caller ID authentication obligations after it becomes eligible to receive’’ a SPC token, the Commission stated that it ‘‘will not consider a voice service provider that diligently pursues a certificate once it is able to receive one in violation of [its] rules.’’). In May 2021, the Governance Authority revised the STI–GA Token Access Policy to enable token access by some voice service providers previously unable to receive a token. In the 2021 annual reevaluation, we found that this policy revision had resolved the main practical concern underlying this extension and that token access no longer stood as a significant barrier to full participation in STIR/SHAKEN. We nonetheless declined to revise this extension on the basis that it remains necessary for the reason the Commission previously identified: ‘‘[A]n entity that meets the definition of a provider of ‘voice service’ cannot comply with the STIR/SHAKEN rules if it is unable to receive a token.’’ We seek comment on this extension and whether it remains necessary. Is it still true that a provider cannot comply with the STIR/SHAKEN rules if it is unable to receive a token? Has anything changed that has made a token unnecessary to participate in STIR/ SHAKEN, making this extension no longer needed? Even if it remains theoretically necessary, are all practical impediments presented by token access resolved, such that we should consider recommending terminating this extension? If we did recommend terminating this extension, when is an appropriate end date? If the extension remains necessary, is token access an impediment to ubiquitous STIR/ SHAKEN? Are there steps the Commission or the Governance Authority could take regarding token access to better promote full participation in STIR/SHAKEN? II. Comments Sought on STIR/SHAKEN Efficacy, Pursuant to Section 4(b)(4) of the TRACED Act When Congress mandated that the Commission require voice service providers to implement STIR/SHAKEN in the TRACED Act, it also directed the Commission to ‘‘assess the efficacy of the technologies used for [the] call authentication frameworks’’ no later than three years after the December 30, 2019 enactment date of the Act. The Commission was also directed to ‘‘revise or replace the call authentication frameworks’’ if the Commission E:\FR\FM\01SEP1.SGM 01SEP1 jspears on DSK121TN23PROD with PROPOSALS 53708 Federal Register / Vol. 87, No. 169 / Thursday, September 1, 2022 / Proposed Rules determines it is in the public interest to do so based on the assessment and to submit a report to Congress ‘‘on the findings of the assessment . . . and on any actions to revise or replace the call authentication frameworks.’’ Pursuant to this Congressional mandate, we seek comment to inform our analysis of the efficacy of the STIR/ SHAKEN caller ID authentication framework that the Commission required voice service providers to implement on their IP networks. (We do not, in this Public Notification, seek comment on caller ID authentication in non-IP networks. In the September 2020 Second Caller ID Authentication Report and Order, the Commission determined that no standardized framework for nonIP networks existed and consequently required providers to work to develop a solution rather than implement a framework. The Commission recently sought comment on whether we should require providers to implement a non-IP caller ID authentication solution. Because the Commission has not yet mandated providers implement any particular non-IP caller ID authentication technology, there is no implemented technology to assess in this required reevaluation.) We start by seeking comment on the standard by which we should assess the efficacy of STIR/SHAKEN. We propose to assess the efficacy of STIR/SHAKEN based on how well it effectuates the authentication of caller ID information. We believe this is the best standard because it evaluates the effectiveness of the STIR/SHAKEN framework at executing the function of the technology mandated under section 4: performing caller ID authentication. We seek comment on this proposal. Is there another way to interpret this statutory language and assess the STIR/SHAKEN framework? For example, should we measure the impact of STIR/SHAKEN on preventing illegally spoofed robocalls, or preventing all illegal robocalls, to determine its efficacy? How would such an approach be consistent with the text of the statute? Would it be an appropriate measure of STIR/ SHAKEN’s effectiveness as a caller ID authentication framework? Or would such an approach only measure the impact and limitations of caller ID authentication generally, regardless of ‘‘the technologies used’’? Could different caller ID authentication frameworks more or less effectively combat illegally spoofed or all illegal robocalls? We next seek comment on the efficacy of the STIR/SHAKEN framework under this standard. Has STIR/SHAKEN proven to effectively authenticate caller VerDate Sep<11>2014 16:46 Aug 31, 2022 Jkt 256001 ID information? Are there ways it could be more effective at that task and, if so, how? Do any specific factors limit its efficacy, and what solutions might resolve those issues? Will any identified concerns be addressed by further deployment across the voice network? In the Bureau’s December 2020 Report to Congress, we stated that, without widespread implementation, it was ‘‘premature to assess the efficacy of STIR/SHAKEN in practice’’ at that time. (The TRACED Act required the Commission to submit that report ‘‘not later than 12 months after’’ enactment.) Since that date, many voice service providers have been required to implement, and have implemented, STIR/SHAKEN. Is it still premature to evaluate the efficacy of STIR/SHAKEN in practice? If so, we seek comment on whether commenters continue to believe that the framework is effective as designed. And if commenters believe we should evaluate STIR/SHAKEN under a different or additional standard, we seek comment on the efficacy of STIR/SHAKEN under any alternative standards proposed. Under any standard, we seek comment on whether the efficacy of STIR/SHAKEN would improve when the framework is paired with other tools or if there are additional steps that the Bureau, Commission, or stakeholders such as voice service providers or the Governance Authority could take to improve the efficacy of STIR/SHAKEN. (Recognizing the benefits of pairing caller ID authentication with call analytics, the Commission adopted a safe harbor enabling voice service providers to block unwanted calls by default based on reasonable analytics that incorporate caller ID authentication information, so long as consumers are given the opportunity to opt out.) Should the Commission consider whether it is in the public interest to revise or replace the STIR/SHAKEN framework? Would revising or replacing the framework at this time be premature, as providers continue to take steps to implement the technology consistent with the Commission’s efforts to bolster its caller ID authentication rule scheme? How would the costs of such revision or replacement compare to the benefits? We ask that any comments indicating that the STIR/ SHAKEN framework is ineffective at authenticating caller ID information identify alternatives that would more effectively authenticate caller ID information.

Synopsis

I. Comments Sought on STIR/SHAKEN Implementation Extensions for Annual 
Review, Pursuant to Section 4(b)(5) of the TRACED Act

    When Congress directed the Commission to mandate implementation of 
STIR/SHAKEN in the TRACED Act, it also required the Commission to 
assess burdens and barriers to implementation, and it gave the 
Commission discretion to extend compliance with the implementation 
mandate upon a public finding of undue hardship. The Commission 
performed this assessment and granted three categorical extensions of 
the STIR/SHAKEN mandate on the basis of undue hardship: (1) small voice 
service providers; (2) voice service providers unable to obtain the 
``token'' necessary to participate in STIR/SHAKEN; and (3) services 
scheduled for section 214 discontinuance. See Second Caller ID 
Authentication Report and Order, 85 FR 73360 (Nov. 17, 2020). (As 
directed by a separate provision of the TRACED Act, TRACED Act Sec.  
4(b)(5)(B), the Commission also granted an extension for those portions 
of the network that rely on technology that cannot initiate, maintain, 
and terminate SIP calls. Because this extension was not granted on the 
basis of undue hardship, we do not seek comment on it in this Public 
Notice.)
    The TRACED Act further requires the Commission to assess burdens 
and barriers to implementation ``as appropriate'' after that initial 
assessment, and directs the Commission to, ``not less frequently than 
annually after the first [extension] is granted,'' reevaluate and 
potentially revise any extensions granted on the basis of undue 
hardship. It requires the Commission to issue a public notice 
explaining ``why such [extension] remains necessary'' and ``when the 
Commission expects to achieve the goal of full participation'' in 
caller ID authentication. To comply with these obligations, the 
Commission directed the Bureau in the Second Caller ID Authentication 
Report and Order to annually reevaluate the Commission's granted 
extensions for undue hardship and revise or extend those extensions as 
necessary. (The Commission determined that the Bureau is in the best 
position to undertake this fact-intensive, case-by-case evaluation.) In 
its directions to the Bureau, the Commission permitted the Bureau to 
further extend an extension to which voice service providers are 
already subject, but prohibited the Bureau from terminating an 
extension prior to the extension's originally set end date. The 
Commission did not permit the Bureau to grant extensions to any voice 
service providers or services not already subject to one. Should we 
further extend a granted extension, we are permitted to decrease, but 
not expand, the scope of entities entitled to that extension based on 
our assessment of burdens and barriers.
    In September 2021, we released a Public Notice seeking comment on 
the Commission's three granted extensions and any associated burdens 
and barriers to the implementation of STIR/SHAKEN. 86 FR 56705 (Oct. 
12, 2021). In December 2021, we issued our first annual reevaluation 
and declined to modify any of the existing extensions. The extension 
for services scheduled for section 214 discontinuance ended on June 30, 
2022. We now seek comment to enable our second annual reevaluation of 
the two remaining STIR/SHAKEN implementation extensions--

[[Page 53707]]

for small voice service providers and for providers unable to obtain 
the required token--granted based on undue hardship.
    Small Voice Service Provider Extension. We seek comment on the 
Commission's extension for facilities-based small voice service 
providers. In September 2020, the Commission granted a two-year 
extension for all small voice service providers, defined as ``a 
provider that has 100,000 or fewer voice service subscriber lines.'' 
Second Caller ID Authentication Report and Order. Under this extension, 
small voice service providers were given until June 30, 2023 to 
implement STIR/SHAKEN. The Commission found that this extension was 
appropriate because small voice service providers may face substantial 
costs--in addition to resource constraints--to implement STIR/SHAKEN 
and confront unique equipment availability issues. In December 2021, 
the Commission shortened the extension for a subset of small voice 
service providers likely to be the source of illegal robocalls. 87 FR 
3684 (Jan. 25, 2022) It shortened the extension to one year--until June 
30, 2022--for non-facilities-based small voice service providers based 
on overwhelming record support and available evidence showing that this 
subset of providers were originating a large and disproportionate 
amount of robocalls. It also required small voice service providers 
suspected of originating illegal robocalls to implement STIR/SHAKEN on 
an accelerated timeline. The Commission maintained the two-year 
extension for facilities-based small voice service providers because it 
found they were less likely to be the source of illegal robocalls. When 
we considered this remaining extension in the 2021 annual reevaluation, 
we declined to lengthen it beyond June 30, 2023, noting that the 
Commission's guiding principle in establishing the extension was ``to 
achieve ubiquitous STIR/SHAKEN implementation to combat the scourge of 
illegal caller ID spoofing as quickly as possible.''
    We seek comment on the burdens and barriers to facilities-based 
small voice service provider implementation and whether we should 
revise their STIR/SHAKEN extension. Have the burdens or barriers 
affecting small providers originally discussed in the Second Caller ID 
Authentication Report and Order, changed since last year's evaluation 
and, if so, how? Should any Commission actions in the previous year 
inform or impact our reevaluation of the small voice service provider 
extension? Have any new burdens or barriers emerged that the Commission 
did not consider or could not have been aware of when it initially gave 
small voice service providers a two-year extension? If so, do these 
burdens or barriers warrant an extension beyond the current June 30, 
2023 date, and if so, how long of an extension is necessary and 
appropriate? How would any additional extension be consistent with the 
Commission's goal of ubiquitous STIR/SHAKEN implementation?
    In response to our Public Notice seeking comment for the 2021 
annual extension reevaluation, the Satellite Industry Association (SIA) 
requested an ``indefinite'' extension for satellite voice service 
providers'' in light of the ``challenging circumstances facing small 
satellite VSPs, combined with their unique economic, operational, and 
technical characteristics.'' The Bureau determined that the record was 
insufficient to evaluate SIA's request at that time, but stated it 
would seek further comment on the request as part of the instant 2022 
reevaluation. In the interim, as part of its May 2022 Further Notice of 
Proposed Rulemaking, 87 FR 42670 (July 18, 2022), the Commission sought 
comment on the larger questions of the applicability of the TRACED Act 
to small satellite providers and whether it should grant such providers 
an extension for implementing STIR/SHAKEN.
    Should the Bureau further extend the small provider implementation 
extension just for small satellite voice service providers as part of 
this inquiry or should we leave this issue to the full Commission to 
consider more generally? Do small satellite voice service providers 
face unique challenges in implementing STIR/SHAKEN? What are these 
challenges? How do they impact this subset of providers' ability to 
implement STIR/SHAKEN? What is a realistic time frame for any extension 
we grant? What impact would an extension for small satellite voice 
service providers have on other providers or the public? What impact 
would such an extension have on the Commission's longstanding goal of 
ubiquitous deployment of STIR/SHAKEN?
    Extension for Voice Service Providers That Cannot Obtain a SPC 
Token. We seek comment on the Commission's extension for voice service 
providers that cannot obtain the Service Provider Code (SPC) token 
necessary to participate in STIR/SHAKEN. In the Second Caller ID 
Authentication Report and Order, the Commission granted voice service 
providers that are incapable of obtaining a SPC token due to Governance 
Authority policy an extension until they are capable of obtaining said 
token. (Recognizing that ``a voice service provider may not be able to 
immediately come into compliance with its caller ID authentication 
obligations after it becomes eligible to receive'' a SPC token, the 
Commission stated that it ``will not consider a voice service provider 
that diligently pursues a certificate once it is able to receive one in 
violation of [its] rules.''). In May 2021, the Governance Authority 
revised the STI-GA Token Access Policy to enable token access by some 
voice service providers previously unable to receive a token. In the 
2021 annual reevaluation, we found that this policy revision had 
resolved the main practical concern underlying this extension and that 
token access no longer stood as a significant barrier to full 
participation in STIR/SHAKEN. We nonetheless declined to revise this 
extension on the basis that it remains necessary for the reason the 
Commission previously identified: ``[A]n entity that meets the 
definition of a provider of `voice service' cannot comply with the 
STIR/SHAKEN rules if it is unable to receive a token.''
    We seek comment on this extension and whether it remains necessary. 
Is it still true that a provider cannot comply with the STIR/SHAKEN 
rules if it is unable to receive a token? Has anything changed that has 
made a token unnecessary to participate in STIR/SHAKEN, making this 
extension no longer needed? Even if it remains theoretically necessary, 
are all practical impediments presented by token access resolved, such 
that we should consider recommending terminating this extension? If we 
did recommend terminating this extension, when is an appropriate end 
date? If the extension remains necessary, is token access an impediment 
to ubiquitous STIR/SHAKEN? Are there steps the Commission or the 
Governance Authority could take regarding token access to better 
promote full participation in STIR/SHAKEN?

II. Comments Sought on STIR/SHAKEN Efficacy, Pursuant to Section 
4(b)(4) of the TRACED Act

    When Congress mandated that the Commission require voice service 
providers to implement STIR/SHAKEN in the TRACED Act, it also directed 
the Commission to ``assess the efficacy of the technologies used for 
[the] call authentication frameworks'' no later than three years after 
the December 30, 2019 enactment date of the Act. The Commission was 
also directed to ``revise or replace the call authentication 
frameworks'' if the Commission

[[Page 53708]]

determines it is in the public interest to do so based on the 
assessment and to submit a report to Congress ``on the findings of the 
assessment . . . and on any actions to revise or replace the call 
authentication frameworks.''
    Pursuant to this Congressional mandate, we seek comment to inform 
our analysis of the efficacy of the STIR/SHAKEN caller ID 
authentication framework that the Commission required voice service 
providers to implement on their IP networks. (We do not, in this Public 
Notification, seek comment on caller ID authentication in non-IP 
networks. In the September 2020 Second Caller ID Authentication Report 
and Order, the Commission determined that no standardized framework for 
non-IP networks existed and consequently required providers to work to 
develop a solution rather than implement a framework. The Commission 
recently sought comment on whether we should require providers to 
implement a non-IP caller ID authentication solution. Because the 
Commission has not yet mandated providers implement any particular non-
IP caller ID authentication technology, there is no implemented 
technology to assess in this required reevaluation.) We start by 
seeking comment on the standard by which we should assess the efficacy 
of STIR/SHAKEN. We propose to assess the efficacy of STIR/SHAKEN based 
on how well it effectuates the authentication of caller ID information. 
We believe this is the best standard because it evaluates the 
effectiveness of the STIR/SHAKEN framework at executing the function of 
the technology mandated under section 4: performing caller ID 
authentication. We seek comment on this proposal. Is there another way 
to interpret this statutory language and assess the STIR/SHAKEN 
framework? For example, should we measure the impact of STIR/SHAKEN on 
preventing illegally spoofed robocalls, or preventing all illegal 
robocalls, to determine its efficacy? How would such an approach be 
consistent with the text of the statute? Would it be an appropriate 
measure of STIR/SHAKEN's effectiveness as a caller ID authentication 
framework? Or would such an approach only measure the impact and 
limitations of caller ID authentication generally, regardless of ``the 
technologies used''? Could different caller ID authentication 
frameworks more or less effectively combat illegally spoofed or all 
illegal robocalls?
    We next seek comment on the efficacy of the STIR/SHAKEN framework 
under this standard. Has STIR/SHAKEN proven to effectively authenticate 
caller ID information? Are there ways it could be more effective at 
that task and, if so, how? Do any specific factors limit its efficacy, 
and what solutions might resolve those issues? Will any identified 
concerns be addressed by further deployment across the voice network? 
In the Bureau's December 2020 Report to Congress, we stated that, 
without widespread implementation, it was ``premature to assess the 
efficacy of STIR/SHAKEN in practice'' at that time. (The TRACED Act 
required the Commission to submit that report ``not later than 12 
months after'' enactment.) Since that date, many voice service 
providers have been required to implement, and have implemented, STIR/
SHAKEN. Is it still premature to evaluate the efficacy of STIR/SHAKEN 
in practice? If so, we seek comment on whether commenters continue to 
believe that the framework is effective as designed. And if commenters 
believe we should evaluate STIR/SHAKEN under a different or additional 
standard, we seek comment on the efficacy of STIR/SHAKEN under any 
alternative standards proposed. Under any standard, we seek comment on 
whether the efficacy of STIR/SHAKEN would improve when the framework is 
paired with other tools or if there are additional steps that the 
Bureau, Commission, or stakeholders such as voice service providers or 
the Governance Authority could take to improve the efficacy of STIR/
SHAKEN. (Recognizing the benefits of pairing caller ID authentication 
with call analytics, the Commission adopted a safe harbor enabling 
voice service providers to block unwanted calls by default based on 
reasonable analytics that incorporate caller ID authentication 
information, so long as consumers are given the opportunity to opt 
out.)
    Should the Commission consider whether it is in the public interest 
to revise or replace the STIR/SHAKEN framework? Would revising or 
replacing the framework at this time be premature, as providers 
continue to take steps to implement the technology consistent with the 
Commission's efforts to bolster its caller ID authentication rule 
scheme? How would the costs of such revision or replacement compare to 
the benefits? We ask that any comments indicating that the STIR/SHAKEN 
framework is ineffective at authenticating caller ID information 
identify alternatives that would more effectively authenticate caller 
ID information.
