voice traffic, which can be both TCP or UDP. It is possible to limit these
port ranges using Group Policy Objects, but even with that, there is no way to
differentiate between voice or video traffic still. Your best bet is to mark
at the client level and have the switches trust the endpoints.<o:p></o:p></span></p>

OCS 2007 R2 and earlier are unable to mark at the client. OCS 2010, aka Wave 14
will do this naively AFAIK but they may make the SIP signaling CS4 rather than
CS3, RTAudio will be EF. So all that "you don't need QoS" statements
from MSFT sales people will change as soon as that is released. Just like they
call their implementation of QoS healing QoE. </span><o:p></o:p></p>

<p class=MsoNormal>Just wondering if anyone has experience setting up QoS on a
network in order to accomodate OCS? I would like to ensure that the OCS packets
are tagged and prioritized according to the organization's QoS policy and
wondering what ports, etc... I should look for in order to identify OCS
traffic.<o:p></o:p></p>
