Generally speaking, the bulk of data flowing in any end-user pipe is contained 
in TCP and that can be rate limited on the receiving side.  UDP traffic 
you're more or less out of luck with unless the ISP supports ECN which many 
do not.

So really the key to VOIP on consumer grade connections simply not to fill 
your pipe, since you have no control over what is prioritised.
