Mobile operators fight robocalls


Suspicious of scams and tired of picking up what turn out to be robocalls, consumers miss important calls due to their reluctance to answer the phone. This impacts businesses as well as consumers, as they may be trying to reach a customer with information about a critical transaction.

Mobile operator T-Mobile says that’s why it’s working to develop new solutions that will help consumers stay spam-free without missing the calls they want. On January 18, the company announced that it was partnering with CTIA, the wireless industry association, to develop best practices for new and improved caller ID for businesses. CTIA facilitates the caller ID best practices (BCI) process and works with several companies in the wireless industry, T-Mobile reports.

BCI will enable businesses and organizations to provide outbound calls that are not only verified, but also include caller ID display, such as the company logo, on supported handsets. It could also allow consumers to see the reason for the call.

“For consumers and businesses that depend on phone calls for critical transactions such as financial services, insurance and healthcare, reliable calls are more important than ever,” T-Mobile said in a press release. .

Complement existing solutions

This new solution will combine authenticated caller ID, STIR/SHAKEN and rich call data (RCD), complementing them by enabling organizations to better identify themselves and providing the information to help consumers make a more informed choice about whether to answer the call.

STIR/SHAKEN is a standard identity authentication technology called ID that enables authentication and verification of caller ID information for calls routed over Internet Protocol (IP) networks, explains the Federal Communications Commission (FCC).

These STIR (Secure Telephone Identity Revisited) and SHAKEN (Signature-based Handling of Asserted Information Using to KENs) standards allow operators to validate a call as soon as they receive it and forward it to another operator and ultimately to the consumer.

The FCC has required providers to implement this in the IP portions of their networks by June 30, 2021.

Achieve high accuracy in call blocking and labeling

AT&T announced shortly after adding STIR/SHAKEN to its existing anti-spam efforts that it was blocking or tagging more than a billion robocalls per month.

“We authenticate and verify hundreds of millions of calls daily, including calls on our own wireless network and calls made with the other two major US wireless service providers,” AT&T said in a press release. . “We also use STIR/SHAKEN data to help us achieve high accuracy in our blocking and tagging.”

Similarly, Verizon announced that it completed upgrading its wireless network to STIR/SHAKEN two years ahead of the FCC deadline and blocked more than 13 billion robocalls.

“Verizon has encouraged the adoption of STIR/SHAKEN, an industry-wide effort that verifies that a call is actually originating from the number displayed on the caller ID and that it is not not spoofed,” the mobile operator said in a press release.
