I hate to tell you, but ANI and caller-id can be spoofed too.

However, I agree that encouraging as much source filtering as possible
would be "a good thing."  Just as long as people don't get the idea
that source filtering would make authentication by source IP address
any more secure than authentication by caller-id.

Now, if we could just get the phone company to not charge 1,000% markup
on caller-id, we'd have it on all our modem lines now.
