On
April 17, T-Mobile and Comcast announced
the launch of “cross-network robocalling protection built on STIR/SHAKEN
standards” and their partnering to provide caller ID verification and alert voice
subscribers to illegal robocalls and scammers. As announced by the two providers
and as described in press reports,
T-Mobile and Comcast are beginning to authenticate calls between their
networks.
T-Mobile is now operating CallerVerified,
its implementation of SHAKEN/STIR protocol, in a number of its devices and with
more devices to be added. Later this year Comcast Xfinity Voice home
subscribers will see caller ID verification messages. Comcast previously
announced a similar partnership with AT&T, and T-Mobile expects to reach
similar arrangements with AT&T and Verizon in the very near future.

Act Would Help Protect Consumers From Illegal Robocalls."
