OK, so does that mean that setting it to 25000 should leave time for the
re-invite or does the timeout start after that.  If so is there another
control for waiting for the re-invite?

Note, a test by my provider shows that this particular number gives the
re-invite after 6 seconds.  I hang up at 4.
