The wiki page is misleading. As the absolute minimum wiki should mention
that you need to restart the system after dropping in new jars. And it
should warn you that once you do that you are no longer running a stable
version of sipXecs.

What's going on here is that you are replacing libraries/jars that are used
by several components: not just sipXbridge. And since other components are
not built against the new versions the chances are something else will
sooner or later get terribly broken.

Running a nightly build of 4.0 would be safer than dropping in couple of
jars from it. The problem is that nightly 4.0 builds are no longer made
public (if someone were to set up independent build server that might help).

4.0.4 only has only 2 issues open at the moment: looks like it should be
our soon.
