For Microsoft Lync 2010 and Microsoft Lync 2010 Attendant clients that run on the Windows 7 or Windows Vista operating system, you can use policy-based QoS to assign the appropriate priority to each media packet. You will need to create a policy for each traffic type for which you want to use QoS. The procedure for each type is the same.

To create a client QoS policy

  1. Log on to the computer as a member of the Administrators group.

  2. Open a Command Prompt window: Click Start. In the Search box, type gpedit.msc, and then press Enter.

  3. In the console tree, expand Computer Configuration, expand Windows Settings, right-click Policy-Based QoS, and then click Create new policy.

  4. In the Policy name box, type a descriptive name for the policy that you are creating, for example, Lync Client Audio QoS.

  5. Select the Specify DSCP Value check box, and then select the DSCP value that you assigned to this media type during the planning phase.

  6. Clear the Specify Outbound Throttle Rate check box, and then click Next.

  7. If this policy will apply to all applications, click All applications. If it will apply only to Lync, click Only applications with this executable name. In the box provided type the file name of the client, for example, communicator.exe, and then click Next.

  8. Allow the policy to apply to all source and destination IP addresses (the default), and then click Next.

  9. In the Select the protocol this QoS policy applies to box, click TCP and UDP.

  10. Under Specify the source port number, click From this source port number or range. In the box provided, type the port range for the media type that you specified during planning, and then click Finish.

You will need to stop and restart Lync 2010 or Lync 2010 Attendant for the changes to take effect.
