If traffic is not TOS marked (i.e. TOS 0), heuristic classification will attempt to automatically classify the trafficby its patterns.TOS is configured on the ShoreTel IP PBX through the ShoreWare Director, navigate to Administration Call Control Options, as illustrated below. Since the numbers are in decimal, the TOS should be configured for 192 or 224.Optimizing ShoreTel Voice Over Ruckus WirelessPage 5
