Preferences – Quality of Service
The Quality of Service pane lets you request a specific transport service for audio, video and signaling traffic.
There are two types of services. The service to use depends on what your internet service provider supports:
• GQoS, which is available for audio and video.
• DSCP (also known as ToS), which is available for audio, video and signaling.
In a network that has the default configuration, the recommended value for audio is 46, because “46” is the
standard marking for audio.
In addition, if you are running Bria on Windows on an Intel® Centrino® Duo mobile-technology-based laptop,
you can request to reserve bandwidth for audio traffic on wireless networks using 802.11e. If bandwidth is
available when the call is placed, it will be reserved for the call, possibly resulting in better audio service.
Bria supports 802.1p QoS packet tagging. If you set up for QoS, Bria will include the specified information in
the packets that it sends to the network provider. Whether the packet is delivered with the specified service
depends on whether your broadband router and the network provider between you and the other party supports
multiple transport services. In other words, whether each network provider reads the QoS information and
prioritizes packet delivery based on the requested service.
