AT&T and Comcast announce exchange of SHAKEN calls

AT&T and Comcast today announced that they’ve exchanged calls between their landline networks using caller ID authentication with STIR/SHAKEN.

AT&T reported that “The test used phones on the companies’ consumer networks—not in a lab or restricted to special equipment. It was conducted March 5, between AT&T Phone digital home service and Comcast’s Xfinity Voice home phone service.”

Further, AT&T reported that this test would “pave the way for AT&T and Comcast to begin offering authentication on calls between networks to customers later this year.”

This is great news for subscribers and businesses. By authenticating and verifying caller ID, the STIR/SHAKEN framework promises to eliminate unauthorized caller ID spoofing, an essential tactic used in the delivery of unwanted robocalls. Such calls are not just a nuisance, either—they often involve schemes to defraud their victims.

We applaud AT&T and Comcast for their work to develop and test this technology in their networks to provide customers with relief from unwanted robocalls.
