Hello, We put together a piece for the IETF blog describing the efforts of the Secure Telephone Identity Revisited (STIR) Working Group, which have received some press attention lately. It highlights the IETF's contribution to an industry-wide effort to rid the telephone network of illegal robocalls and fraud that depend on calling number impersonation. If you're interested to get some background on STIR, or to read about the direction of ongoing work, this is hopefully a good place to get started. https://www.ietf.org/blog/stir/ Thanks!
