[cisco-voip] auto QoS for Ip telephony solution

[Ed Leatherman]

Hi Erik,

I'm no qos expert by any stretch, this is just what we do and it seems to
work out for us.. traffic markings come out end-to-end how we want them to
at least. If someone else sees something wrong with it i'd love to hear it.

I've been using "auto qos voip trust" on both those instances, i've been
adding to that "mls qos trust dscp" to the callmanager ports and layer 3
links, because the auto trust statement seems to put mls qos trust cos
instead. To my understanding the callmanager servers mark their traffic with
the dscp bits.
