Basically, I've used 403 (Forbidden) when a UAC tries to register

And I've used 404 (Not Found) when a UAC sends a non-REGISTER

I used to have 403 for that, but I received
some comments from somebody on the list that 404 (Not Found) would
be more appropriate.
I don't feel strongly about this issue.
If anybody has any ideas, please go ahead.
Nonchair comment:
If we agree that SIP and SIPS point at the same thing, then rejecting
a SIP request with a 404 when there is an "equivalent" registration
seems wrong. 403 seems better, but what it seems like we need is an
"Invalid Scheme" response. I'm also tempted by 488 (Not Acceptable
Here) even though we normally use that for SDP.
Even a 400 (Bad Request) seems better than 404.
