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) https://authenticate.iconectiv.com/authorized-service-providers-authenticate -Paul On 9/10/20 4:09 PM, Michael Thomas wrote:

Promoting Caller ID Authentication to Combat Spoofed Robocalls – The Commission will consider a Report and Order that would continue its work to implement the TRACED Act and promote the deployment of caller ID authentication technology to combat spoofed robocalls. (WC Docket No. 17-97)
So I have a question: what percentage of traffic in the US is really coming from the legacy PSTN? My understanding is that it's pretty low these days.
If that's true, it seems to me that this is a SIP problem, not an e.164 problem.
