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)
