You can disable UDP - that prevents from faked messages, but causes lots of interoperability problems.
Disabling UDP won't prevent faked messages. You don't have to inject the faked message into the same tcp connection (which would be difficult). You can open another tcp connection and send the faked BYE on it. There is nothing that would prevent this (and there are/were some UAs that opened a different tcp connection for each request).
