Phone scammers will soon lose a major advantage

The Federal Communications Commission is taking aim at a key loophole that helps robocallers dodge detection systems meant to protect consumers. If you’re still getting bombarded with scam calls on your phone, this gap involving older network technology is a likely contributor. The FCC wants to ensure calls maintain their digital fingerprints even when passing through these older networks.  

Modern phone calls over internet (IP) networks benefit from STIR/SHAKEN, a system the FCC champions for tracking, blocking, and warning about bad calls. It acts like a digital fingerprint to verify caller ID isn’t faked or “spoofed”. It’s crucial for spotting malicious calls before they potentially trick someone.  

The problem is that when calls travel — even partially, through older, non-IP phone lines (think traditional landlines) — this STIR/SHAKEN verification often gets lost due to technical limitations of those networks. Scammers know this and actively exploit it by routing calls through these pathways, effectively erasing the digital proof of origin. This makes their illegal calls much harder for carriers to identify and block.  

Patching the network hole

The FCC’s new proposal directly targets this non-IP loophole. For the last four years, providers using these older networks faced delayed deadlines for implementing call authentication required by the TRACED Act. The FCC now wants to end these delays and get authentication solutions deployed.  

This initiative stems from the TRACED Act, which is legislation designed specifically to bolster the fight against the flood of illegal robocalls. While STIR/SHAKEN on IP networks has certainly made a dent, billions are still lost annually to frequent phone scams related to everything from fake auto warranties to government impersonations, seriously damaging consumer trust. Addressing specific vulnerabilities like the non-IP gap is essential.

Shutting down this specific loophole won’t magically stop all robocalls overnight, but it’s a necessary technical fix in the ongoing battle. Ensuring calls retain authentication across different network types makes it tougher for scammers to operate anonymously and hide their tracks. Ultimately, closing this gap should lead to fewer fraudulent calls getting through to consumers and hopefully increase the reliability of caller ID.
