Comcast battles robocalls with voice verified caller ID

It will be the largest landline voice implementation of the technology in the US

Comcast battles robocalls

Nobody likes robocalls but even with different kinds of enforcement, the problem remains persistent. YouMail reports that the US received under 46 billion robocalls in 2020 with February alone, for a total of 4.8 billion robocalls. Interestingly enough, even with the gravity of these figures, these are still considerably lower than the recorded all-time high of 58.8 billion robocalls made during 2019.

Comcast aims to battle this by rolling out the nation’s largest landline voice implementation of STIR/SHAKEN-based Verified Caller ID to its customers. Secure Telephone Identity Revisited (STIR) and Signature-based Handling of Asserted Information (SHAKEN) are two technologies that Comcast engineers helped develop to allow voice providers to “sign” and “verify” caller ID. This helps curb caller ID spoofing which is a method that tricks providers with spoofed or false caller ID information to reach their customers.

The landline voice implementation of STIR/SHAKEN-based verified caller ID will be available to Xfinity Voice, Comcast Business Voice, and Business VoiceEdge Select customers. Customers will now be able to see a label indicated that the caller ID information is verified and authenticated to make sure that the call really is coming from the number shown on the caller ID.
