4.5 Preferences – Quality of Service
The Quality of Service panel 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 VoIP 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.
Bria Professional supports 802.1p QoS packet tagging. If you set up for QoS, Bria Professional 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.
