Explanation

Note that Microsoft Lync Server 2013 does not support QoS for other Windows operating systems, such as Windows Vista or Windows XP. The port ranges and DSCPs must be different for audio and video. To create a Quality of Service audio policy for Windows 7 or Windows 8 computers, first log on to a computer where Group Policy Management has been installed. Open Group Policy Management (click Start, point to Administrative Tools, and then click Group Policy Management) and then complete the following procedure: - In Group Policy Management, locate the container where the new policy should be created. For example, if all your client computers are located in an OU named Clients then the new policy should be created in - Right-click the appropriate container and then click Create a GPO in this domain, and Link it here. - In the New GPO dialog box, type a name for the new Group Policy object in the Name box (for example, Lync Audio) and then click OK. - Right-click the newly-created policy and then click Edit. - In the Group Policy Management Editor, expand Computer Configuration, expand Policies, expand Windows Settings, right-click Policy-based QoS, and then click Create new policy. - In the Policy-based QoS dialog box, on the opening page, type a name for the new policy (e.g., Lync Audio) in the Name box. Select Specify DSCP Value and set the value to 46. Leave Specify Outbound Throttle Rate unselected, and then click Next. - On the next page, make sure that All applications is selected and then click Next. This setting instructs the network to look for all packets with a DSCP marking of 46, not just packets created by a specific application.
