Hi,
If its a cloud conferencing system, most likely the traffic is encrypted
which makes it difficult to be identified using application engines (such
as cisco nbar or riverbed afe).
The only option you have to tweak the system configuration to use custom
ports (other than the common ones for internet such 80 as 443), then use
MQC rules to create qos policies. These policies will be applicable only
within your network. Outside the network over internet, no qos.
