T-Mobile says that it and a group of other companies have completed a wireless call combining authenticated caller ID and Rich Call Data (RCD) using the STIR/SHAKEN framework and protocols. The initiative is aimed at protecting people receiving calls from spoofers and spammers.

First Orion, CTIA, Everbridge, iconectiv, NetNumber, Numeracle and Twilio also participated in the proof of concept test.

T-Mobile says that previously caller ID information was taken from third party databases that could provide inaccurate information. RCD is taken by the receiving end of the call directly from the organization that is calling and therefore is virtually certain to be accurate. In addition, RCD is part of the STIR/SHAKEN framework. This means that the information will not be displayed unless it is authenticated by the network. 

“The ability to deliver RCD to mobile devices is a key tool in the battle against scammers as it increases consumer trust in knowing who is calling them and why,” T-Mobile CTO Abdul Saad said in the press release. “This proof-of-concept shows that by working together as an industry we can make sure that legal, critical, and wanted calls are delivered with a high level of consumer confidence.”

The above image illustrates three pieces of information delivered to the phone: The calling name or label, the reason for the call (i.e., “customer service calling”) and the company logo.

There was a lot of STIR/SHAKEN news during the past few months as the June 30 FCC deadline to implement the technology on certain portions of their networks approached. 

In March, T-Mobile said it was working with Spectrum Voice from Charter Communications on the protocol and thus was “effectively” partnering with all major US networks. On June 30 – deadline day — the service provider said that it had filed a certification of completion of implementation with the FCC. The filing is certification that all calls originating on its network are STIR/SHAKEN compliant.
