We have started a new effort to reduce robocalling, swatting and vishing in a SIP network following the ideas presented by Henning Schulzrinne in his presentation at IETF 86 Orlando and the recent SIPNOC.  Fundamentally, we plan to minimize the ability to spoof the caller's id.   We have created a new ietf list, [email-masked]<mailto:[email-masked]>, where stir stands for "Secure Telephone Identity Revisited".

Our emphasis in this effort is deployable solutions that can significantly reduce problems in a year or two, not solutions that take a revolution in how service provider and enterprises deploy SIP networks.  For that reason, we are particularly interested in getting active participation by as many SIP service providers as possible, as well as the vendors that serve them.

Some discussion has been ongoing among a group of us, and a meeting was held last week to see if we had enough common vision to initiate an IETF effort we thought would actually get deployed.  So if you get on the list, you will see discussion on specific points already underway.

If you are interested in working on this effort, or want to stay informed, you can subscribe by visiting:

We hope to arrange a session in Berlin, details will be forthcoming.
