Do you know where quantum is used for? It's for classes that are asking for
remaining bandwidth. So if that "one voip user" is never asking for more
then the configured rate of its class, quantum is never used. So it really
depends on how you configured the classes to answer that question.
And taking a quantum of 10 byte is not "wrong". But if you send 1000byte and
your quantum is 10byte, htb will use 10byte in it's calculations. So it can
disturb the setup, but nothing bad will happen.
