Options – Advanced – Quality of Service
The Quality of Service pane lets users request a specific transport service for audio, video and signaling traffic.
There are two types of services: the proper service depends on what a user’s 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 addition, when running X-Lite within Windows
®
on an Intel
®
Centrino
®
Duo mobile-technology-based
laptop, users can request reserved bandwidth for audio traffic on 802.11e wireless networks. If available when
the user places a call, X-Lite will reserve bandwidth for the call (which may lead to improved audio quality).
Some versions of Windows
®
restrict the services that users can access:
