Report Indicates Robocallers are Making Heavy Use of Smaller Networks

On September 12, Transaction Network Services (TNS) released its "2019 First Half Robocall Investigative Report." According to the TNS Report: "The data suggest that while top carriers are making inroads in the fight against robocalls, VoIP providers and smaller regional carriers need to take more aggressive action as bad actors shift focus to their networks." The top six U.S. carriers represented 70% of total calls during the first half of the year, "but only 12% of high-risk calls are from numbers owned by these carriers." 

The TNS Report found that "[R]obocallers may shift focus to smaller, regional carrier networks." As pointed out in a September 12 USA Today article, many smaller carriers appear to be behind the major carriers in implementing STIR/SHAKEN technology to verify that numbers displayed on Caller ID actually placed calls. And it appears that efforts by major carriers may be responsible for reducing robocalls originating in their respective networks. 

As mentioned in my August 23 blog post, a dozen major carriers have entered into an agreement with all fifty State Attorneys General to combat illegal and unwanted robocalls and caller ID spoofing, including by implementing STIR/SHAKEN. On legislative efforts in Congress to protect consumers from scam and unwanted calls, see my April 15 blog post.
