The problem is there is legitimate reason to spoof CID.
VOIP is one. I also have the ability to do it when I make a call from my work cell to have it display the city switchboard so people both aren’t calling me when I’m off duty, but also so that the people receiving calls see a call from the City, not from some random dude.
This is already being worked on with STIR/SHAKEN. Very similar to certificates with websites. You want to place a call as a certain number? Where is your proof you own that number? Now we’ll place your call. Your cell’s recent call list should already be showing little check marks on certain callers. Those are authenticated.
