Yep.

I've done this sort of thing to get around NAT problems, that's about  
it.

Perhaps their theory is that a VPN gives them a "private" network, and  
they've heard that "private" networks do VoIP better.
Obviously, a VPN doesn't give you control of the packets on the wire  
like a private network does, so that theory doesn't work.
