What you seem to be missing is the fact that so many people say "You 
must have QoS on your LAN to make voice work well."  In my experience 
that is not the case and creates needless complication on your LAN.

My general policy is "Plan for QoS on the LAN (only buy switches that 
can do it), but only actually set it up if it's needed."  Of course, QoS 
on a WAN is totally different.
