Quality of Service
I'm not knowledgeable with QoS (yet another thing I need to learn at some point).
How is QoS implemented for voice when you have a L2 access layer? From what I've been reading it sounds like you don't implement QoS at the access layer, you implement CoS instead. Is this correct?
What about at the distribution layer where routing takes place? Is QoS necessary there?

I believe the call signaling by default is CoS 3 at the Layer 2 level and is mapped to the DSCP CS3 PHB at Layer 3.
Depending on your scenario you may want to use a higher DSCP PHB for signaling.
