FCC: rulemaking on STIR/SHAKEN and Caller ID Authentication

Thu Sep 10 21:19:24 UTC 2020

A *LOT* goes through at least one TDM transition (so you can kiss that 
identity header goodbye). None of the big names in long distance 
termination support STIR/SHAKEN. There's about 4-5 that will do 
STIR/SHAKEN outside of testbed connectivity (my employer is one). One 
big name is still using a self signed certificate to sign their 
STIR/SHAKEN calls, it'll expire in a couple weeks so they should figure 
life out quickly. I won't shame them here.

The lions share of intercarrier traffic won't go through SIP until the 
big ILECs are required to interconnect over SIP in reasonable and 
non-discriminatory ways. I'm not holding my breath.

(AT&T Wireless and Verizon Wireless hide behind their respective 
landline networks generally, and without SIP connectivity to those, you 
won't be getting green checkmark calls to people on the two largest 
wireless carriers outside of private testbed connectivity anytime soon)
