Just one point, it's not advisable to mix allow and deny like that -
it isn't treated as a "do this, do that, else something" sequential
process. I don't recall the details but it can produce result you
don't expect.
Normal advice is to just use allow, or just use deny. Allow implies
deny everything that doesn't match, deny implies allow everything
that doesn't match.
So in the above, 'allow members of "data";' will implicitly deny
everything except members of "data" - and so implicitly deny members
of "voip".
