AT&T Reports 1 Billion Robocall Blocks Per Month As STIR/SHAKEN Deadline Nears

American telecom giant AT&T has announced an update of the company’s effort toward combating the momentous rise in spam phone calls. According to AT&T representatives, the company’s anti-spoofing programming is preventing 1 billion fraudulent calls per month, more than double the amount of the previous year. 


Over the last few years, mobile users across the country have experienced a noticeable rise in the amount of spam calls, leading telecom service providers to devise new strategies to prevent calls from successfully reaching customers. The problem became exacerbated over the course of the pandemic, due to a reduced workforce and dependence on remote activity. In fact, a recent CNBC article found that Americans collectively lost $29.8 billion in 2020 alone. To address this increase in criminal activity, AT&T created a “triple-barrelled” protection in combination with AT&T ActiveArmorSM, to help manage suspicious activity:

-AT&T Call Protect gives wireless customers automatic fraud blocking and suspected spam alerts.

-Our global fraud team runs an additional program that blocks fraud calls to every type of AT&T phone service.

-STIR/SHAKEN, a new call authentication technology, is now boosting both programs with extra data for detection and accuracy.

Coincidently, the update from AT&T has arrived only a few days before the FCC’s STIR/SHAKEN protocol reaches the compliance deadline. To those who are unfamiliar, STIR/SHAKEN is a set of government protocols that hopes to provide customers with better protections against the recent rise in fraudulent calls from global VoIP systems.

"With AT&T ActiveArmorSM, we detect and prevent security issues with multiple layers of protection," said Jenifer Robertson, chief customer officer, AT&T Consumer. "Our robocall efforts are a prime example."Our ultimate goal is to be able to report fewer blocked calls, as an indication that fewer illegal calls are being sent. We'll continue to work with law enforcement and the Industry Traceback Group to trace illegal calls back to the source."
