Improved QoS support in H323plus
To All
I have updated QoS support in H323plus. DSCP (Diffserv) is now enabled by default (if compiled with DNS support). Transport QoS is now also negotiated between the parties during the capability exchange with the higher QoS value given precedence over the lower value for both direction media flow.
The default values for DSCP are 46 (guaranteed) for audio and 26 (controlled load) for Video. You can change these by calling statics H323AudioCapability::SetDSCPvalue() and H323VideoCapability::SetDSCPvalue() from your application. You can also turn off the feature via a new function H323EndPoint::DisableH245QoS().

Forgive my lack of understanding, what does DSCP have to do with DNS? Why the relationship here?

You are correct it was a typo. My bad I mean compiled with QoS support :). For windows it requires the platform SDK.
