It is possible for IP networks to differentiate between and prioritize data packets being transmitted through routers across networks. This is useful because in modern data networks many different IP services like email, voice, web pages, video and streaming music coexist within the same network infrastructure.
Broadcast IP audio data packets can be configured for expedited or assured forwarding (Quality of Service or QoS) when traversing different networks. Routers can also be configured to ignore these forwarding priorities so they are not assured across all networks.
The codec can be configured to prioritize IP data packets sent across a network by entering a value into the Differentiated Services Code Point (DSCP) field within the header of data packets transmitted by the codec over the network. Check with your IT administrator before changing this setting. By default the codec is configured for Assured Forwarding and more details about DSCP are available on Wikipedia at http://en.wikipedia.org/wiki/Dscp.
