The average consumer receives 13 spam or fraud calls monthly, requiring adaptive AI defenses beyond static databases
Spam calls remain one of the most frustrating digital nuisances of modern life. In January 2025 alone, 4.7 billion spam calls were placed to Americans. The financial toll is staggering: the first half of 2023 saw approximately 78 billion robotexts and 31 billion robocalls, leading to estimated losses exceeding $46 billion.
What makes 2025 different is the sophistication of these attacks. Voice deepfake scams have entered the mainstream, with scammers using AI to clone voices and create convincing impersonations. Traditional blockers that rely on static databases simply cannot keep pace. AI-powered privacy management solutions are now essential for anyone serious about protecting themselves from unwanted calls and the fraud they often carry.
Spam Calls in 2025: Why We Still Need AI-Powered Privacy Management
The robocall problem has evolved far beyond simple nuisance calls. According to Truecaller's U.S. Spam and Scam Report, 92% of Americans received spam calls in 2023, and 86% received spam texts. The consequences are real: 56 million Americans reported losing money through scam calls in 2023, representing 21% of adults.
Generative AI has escalated these challenges dramatically. Advancements in natural language processing enhance the sophistication of scams, facilitating convincing social engineering attacks. Scammers now use AI-generated voices, spoofed caller IDs, and hyper-targeted messages that make it increasingly difficult to distinguish legitimate calls from fraud attempts.
The scale of operations is alarming. In 2021, a single spammer from India was responsible for generating over 202 million spam calls. This industrialized approach to phone fraud requires equally sophisticated defenses.
Is Robokiller Still Effective Against Modern Spam Calls?
Robokiller was once a go-to solution for spam call blocking, using AI-powered call screening to answer calls and waste scammers' time. The app claims to use a global database of 1.4 billion analyzed calls and AI-powered audio fingerprinting technology. However, recent user data tells a different story.
The app's safety score has fallen to 55.8/100, with 37.2% of reviewers reporting negative experiences. User complaints reveal several critical issues:
Legitimate calls from friends and family getting blocked
The fundamental problem is that static block-list models struggle against modern AI-driven spoofing tactics. When scammers can generate new numbers instantly and use sophisticated voice cloning, a database-dependent approach becomes reactive rather than proactive.
What Makes an AI Spam Call Blocker Effective in 2025?
Effective spam call blocking in 2025 requires more than a large database. Here are the technical and privacy requirements modern solutions must meet:
Real-time AI call screening: Systems must analyze caller behavior during the call itself, not just check numbers against lists. Using natural language processing and machine learning, effective systems analyze call content and interaction patterns to distinguish humans from bots.
STIR/SHAKEN integration: The STIR/SHAKEN framework authenticates caller IDs by digitally signing calls to verify legitimacy before they reach recipients. However, STIR/SHAKEN authenticates carriers, not individual caller IDs, which limits its effectiveness against sophisticated spoofing.
Caller ID Verification protocols: Emerging alternatives like CIV (Caller ID Verification) authenticate the actual caller ID through challenge-and-response processes. Compared with STIR/SHAKEN, CIV works with both IP and non-IP networks and does not require trusted certificate authorities.
On-device privacy: The best solutions process calls locally rather than sending your data to external servers. This protects your privacy while still providing robust screening.
Adaptive learning: AI models need to continuously adapt to new threats. The average U.S. consumer receives 13 spam or fraud calls per month, and the tactics behind those calls evolve constantly.

Cloaked Call Guard
Cloaked's Call Guard uses AI-powered real-time call filtering to stop spam, scam, and telemarketer calls before they ring your phone. Every call from a number not in your contacts is automatically screened, with an advanced AI model engaging callers to detect scams in real-time.
The results from a family-focused pilot are compelling: An 83% reduction in spam calls and a 91% reduction in suspicious calls. Most significantly, potential AI scam attempts dropped to zero.
What sets the platform apart is its comprehensive approach. Beyond call screening, 120+ data brokers are targeted for removal of personal information, addressing the root cause of targeted scam attempts. The service also includes $1 million identity theft insurance for eligible losses.
Major carriers and operating systems offer baseline protections:
Carrier solutions:
AT&T ActiveArmor provides automatic fraud call blocking and suspected spam warnings. AT&T scored highest among carriers surveyed, earning an A on services despite only partial anti-robocall technology compliance.
Verizon Call Filter helps identify, block, and report spam calls. However, Verizon charges $3.99 per month for its Call Filter Plus app with enhanced features.
T-Mobile Scam Shield offers free scam call blocking for all users, combining automatic blocking with scam ID notifications.
OS-level features:
iPhone's Silence Unknown Callers sends calls from numbers not in your contacts straight to voicemail.
Most Android phones offer Caller ID & Spam Protection that flags suspicious calls and can block known spam automatically.
The challenge with carrier protections is inconsistency. A survey of 24 major phone companies found that half earn D or F grades for how well they protect customers from robocalls. Top carriers have successfully signed and verified 86% of traffic between them, but smaller carriers on legacy networks remain vulnerable.
Third-Party & Research-Grade Tools
Several innovative alternatives outperform legacy apps:
YouMail blocks known spam numbers automatically and plays an "out of service" message to trick robocallers. This approach can actually get you removed from spammer lists since the number appears disconnected.
Google Call Screen for Pixel phones detects spam based on what a caller says or by matching against Google's database of known spammers. AI-powered replies are generated on-device, and transcripts are stored only on your phone.
RobocallGuardPlus, developed by Georgia Tech, represents a research-grade approach. The system blocked 95% of mass robocalls, 82% of evasive robocalls, and 75% of targeted robocalls in user studies of 8,000 robocalls. It uses a smart virtual assistant with natural language processing to engage callers in conversation, accurately distinguishing between human and robotic callers.
How Do TCPA and STIR/SHAKEN Regulations Affect Your Spam-Call Defenses?
Understanding the legal backdrop helps explain why certain protections exist and what recourse you have.
TCPA (Telephone Consumer Protection Act):
The TCPA has long been a focus of privacy litigation. In December 2024, 85.3% of all TCPA filings were class actions, and January 2025 saw filings up over 250% year-over-year. The 2021 Supreme Court ruling in Facebook v. Duguid narrowed what qualifies as an automatic telephone dialing system, but litigation continues to surge.
For consumers, the TCPA provides the right to sue companies for unauthorized calls, with damages of $500 per violation (or $1,500 for willful violations).
STIR/SHAKEN:
Required by the TRACED Act of 2019, STIR/SHAKEN mandates that carriers authenticate caller ID information. Top carriers now sign 95% of call traffic with "A level" attestation. However, the framework's limitations became apparent when the FCC proposed a $2 million fine against Lingo Telecom for applying incorrect STIR/SHAKEN attestations to deepfake robocalls impersonating President Biden.
FCC enforcement:
The FCC has removed twelve companies from the Robocall Mitigation Database for non-compliance and ordered blocking of traffic from 185 companies. This enforcement pressure drives product design toward compliance-first approaches.
How to Choose the Right AI Privacy Solution in 2025
Selecting the right protection requires matching your needs to available solutions. Here's a practical framework:
1. Assess your exposure level. If you receive more than the average 13 spam or fraud calls per month, you need more than basic carrier protection. Check whether your personal information is already available through data brokers.
2. Prioritize proactive over reactive. Database-only solutions will always lag behind scammers who generate new numbers constantly. Look for AI-driven real-time screening that analyzes caller behavior during the call itself.
3. Address the root cause. AI's ability to craft sophisticated phishing messages poses significant challenges to detection systems. Solutions that combine call blocking with data removal from brokers reduce your attack surface.
5. Evaluate privacy trade-offs. Some solutions require significant data access. The best approaches keep your real phone number out of the hands of bad actors by using unlimited phone and email aliases.
