In the growing effort to combat robocalls, T-Mobile and Comcast announced this morning that they are the first to allow cross-network protection for their customers. This is a big step in the fight over call verification as robocallers continue to attack our phone lines with spam.

T-Mobile and Comcast are utilizing the STIR/SHAKEN standards to verify/authenticate calls that occur between their networks. Starting today, T-Mobile customers will get that verification from calls that originate from a Comcast Xfinity Voice number, while Xfinity Voice customers will get the same from T-Mobile calls “later this year.”

In addition to the cross-network news, T-Mobile says that the┬áCaller Verified service that’s a part of protecting customers from robocalls, now works on 10 smartphones, including LG G8 ThinQ, Samsung Galaxy Note8 and Note9, Samsung Galaxy S8, Galaxy S8+, Galaxy S9, Galaxy S9+, Galaxy S10e, Galaxy S10 and Galaxy S10+. Caller Verified implements the STIR/SHAKEN verification I just mentioned above to show customers that calls coming to their phone are “Verified.” Those will now included calls from Comcast home numbers on all of those phones, once they’ve been updated to the latest available software.

This is good news! Now we just need all of these wireless carriers to come together to do similar things.
