On Wednesday, T-Mobile and Comcast announced a partnership to combat the industry's growing problem of robocall. As of today, companies will begin to authenticate calls made between their networks to verify if consumers are people who actually call them.
Americans received more than 26 billion unwanted phone calls last year, and after some push from federal agencies Like the Federal Communications Commission, operators are beginning to implement an authentication system designed to combat them , known as the SHAKEN / STIR protocol. T-Mobile and Comcast will begin using the protocol to authenticate calls made between the two networks on a handful of devices.
"Automatic calls and spam calls are a problem throughout the industry, and we must join forces to keep consumers protected.Today, we are the first to cross industry lines to do just that," he said. John Legere, CEO of T-Mobile.
The SHAKEN / STIR protocol verifies authentic calls by using digital certificates that help determine where a call is being placed. If a caller is identified, T-Mobile will display "Caller Verified" in the caller ID. T-Mobile began verifying some calls within its own network in January, and this partnership will extend it to calls made between T-Mobile customers and customers of Comcast's residential telephone service.
The protocol will begin to be implemented in 10 devices, including the LG G8 ThinQ, the Samsung Galaxy Note 8 and Note 9, the Galaxy S8, S8 Plus, S9, S9 Plus, S10, S10 and S10 Plus. T-Mobile says it will soon be available on Galaxy Fold and A6 and other devices on its networks in the coming weeks and months. Comcast customers will have to wait until "later this year" before seeing the verification message.
"Fraudulent calls hurt everyone, so we want to give consumers more power to protect themselves," Eric Schaefer, senior vice president of Comcast Cable, said. "Our engineers played a key role in the development of this technology for the entire industry, and we are pleased to work with T-Mobile to offer another first in the fight against fraudulent calls."
In March, AT & T announced its SHAKEN / STIR partnership with Comcast as well, but call verification between the two networks has not yet begun. T-Mobile said it would likely partner with other carriers such as AT & T and Verizon in the coming months to authenticate more calls between networks.
The SHAKEN / STIR system has some limitations. For now, he is only able to verify that the person on the other line is a human. It can not detect spam calls. That means that the system will be much more useful as more networks implement it and allow you to authenticate calls between service providers.
