i do not use any of it, and, i do not think it is even required. 
normally cable/dsl links are asymmetrical, so your outbound is already 
capped at 128k or whatever. inbound is whatever speed you have. i have 
2mbit. at this speed i can run speed test (from dslreports.com) and talk 
on the phone at the same time and hardly notice anything. sometimes 
things may get bad for a few seconds (like bad cell phone), but normally 
it will recover.

if you really want to do shaping then use dummynet(4). just create a 
pipe between vonage servers and your box and set it up the way you like.

btw, a friend of mine uses vonage behind his smc barricade router. seems 
to work just fine. he said he did not have to open anything on the router.
