STIR/SHAKEN

According to this doc: https://docs.fcc.gov/public/attachments/FCC-20-42A1.pdf, VOIP providers must implement STIR/SHAKEN by June 30, 2021.  And furthermore, Comcast reports in this report that by the end of 2019, "virtually all calls...terminating with a Comcast residential subscriber are fully authenticated through the STIR/SHAKEN protocol".

 

We still get 3 or more ID-spoofed calls a day.  Is STIR/SHAKEN actually implemented?  Have the bad guys figured out a way around this technology?  Why are we still getting these calls?

You left out a critical part of that quote:


... “virtually all calls originating from a Comcast residential subscriber and terminating with a Comcast residential subscriber are fully authenticated through the STIR/SHAKEN protocol.

The claim is only for Comcast residential to Comcast residential calls. Calls from other systems to a Comcast number may or may not have the data needed to allow the caller ID info to be authenticated.

 

Unrelated, your link has a trailing comma which, for reasons I don't understand, causes a DOCX document to be downloaded instead of a PDF. The PDF link is https://docs.fcc.gov/public/attachments/FCC-20-42A1.pdf.
