TNS Half Year 2024 Robocall Report: Smaller Carriers Increase Signed Call Traffic, But Interconnectivity Challenges Limit STIR/SHAKEN Gains

Analysis of more than 1.5 billion daily call
events finds tier-1 carriers building on STIR/SHAKEN success
signing call traffic and delivering highest call authentication
level
Smaller carriers successfully increased the total volume of
signed call traffic in the first half of the year: 30 percent of
call traffic between non-top seven carriers is now signed and
verified with STIR/SHAKEN protocols, up from 22% in 2023. However,
Transaction Network Services' (TNS) Half Year 2024 Robocall
Investigation Report, released today, also finds that network
interconnectivity challenges are blunting the full benefits
STIR/SHAKEN can deliver to consumers and businesses, while bad
actors are increasingly leveraging AI to launch robocall
attacks.
The TNS report, a data-driven analysis of robocall trends,
suggests a critical transition period is underway for carriers,
regulators, and other telco stakeholders committed to supporting
smaller carrier digital transformation efforts, combating
increasingly sophisticated AI-powered deepfake scams, and
protecting voters from robocall disinformation campaigns leading
into the 2024 US Presidential election.
“The fact that three-quarters of total call traffic is signed
and 85% of all calls between tier-1 operators are signed speaks to
how far carriers of all sizes have come with STIR/SHAKEN and
protecting subscribers,” said Denny Randolph, President of TNS
Communications Market. “Still, there is more work to be done: SIP
interconnectivity issues mean that smaller carriers doing all the
right things with STIR/SHAKEN and call signing aren’t yet
experiencing the full value of those investments.”
To drive further call signing and authentication gains, there
are tangible steps telco stakeholders can explore to address legacy
network interconnectivity issues:
- Regulators. Continuing to enable smaller carrier SIP
network transitions and interconnection is vital. There is also a
need to acknowledge the budget challenges smaller carriers face in
undertaking digital transformation efforts. TNS’ Robocall Report
data affirms that increasing termination call signing will benefit
from advancing industry solutions that deliver ubiquitous
connectivity so non-tier-1 carriers can reach thousands of networks
without having to peer with each one individually.
- Smaller Carriers. Smaller carriers can expand their SIP
interconnectivity and mitigate the impact of SIP breakage by
deploying solutions like Call Guardian Authentication Hub (CGAH)
and IP Voice Transit services, which allow them to tap into
advanced call mitigation solutions (Branded Calling, Caller ID,
etc.) and bypass connectivity challenges with SIP to SIP peering –
even if they haven’t fully migrated to IP networks.
- Tier-1 Carriers. TNS Robocall Report data continues to
reflect the gains that tier-1 carriers (Verizon, UScellular,
T-Mobile, Lumen, Comcast, Charter and AT&T) are making with
signed calls and ensuring that call traffic is signed with
Attestation “A”. There have been great strides in enabling a
trusted ecosystem in which the value of STIR/SHAKEN can be seen.
However, there remains value for tier-1 carriers to support closing
the remaining interconnectivity gaps so the full benefit of the
standard can be realized.
The latest edition of TNS’ Robocall Investigation Report also
includes several new robocall insights to inform carriers,
regulators, policymakers, and the telecom industry on key trends
and developments thus far in 2024 and what might occur in the
second half of the year:
Political Disinformation Attempts to Increase Ahead of
Election Season
Following the massive volume of political robocalls early in the
US election primary season, political robocall activity ebbed due
to FCC punitive moves and reduced stakes as Presidential
nominations were secured.
However, TNS expects political disinformation attempts -
including AI deepfakes - to increase closer to the November US
Presidential election. In Q3, bad actors are likely to sow
misinformation aligned with key milestone events, including the
Republican and Democratic conventions and any future presidential
debates.
Americans Must Guard Against AI-Generated Robocalls
Generative AI has supercharged robocalls by replicating the ten
qualities of a voice —volume, pace, tone, pitch and enunciation,
among others — making scams seem much more realistic.
Americans must be proactive in protecting their voices from
being cloned by AI. This means changing their voicemail greetings
to an automated tone, creating a family safe word, and embedding
secondary safe words in messaging apps like FaceTime and
WhatsApp.
To support carrier and business efforts, TNS launched AI Labs to
develop new AI solutions that protect Americans from AI robocall
scams and lead the fight against bad actors.
