Hi Erik,<br><br>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.
<br><br>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.
