3.1 System Requirements

The computer on which you want to install the endpoint for Microsoft Windows must meet the following requirements:

Requirement

Notes

Microsoft Windows operating system

One of the following, with the latest service packs installed:

  • Windows Server 2016

  • Windows 10 (32-bit or 64-bit)

  • Windows Server 2012 R2

  • Windows 8.1 (32-bit or 64-bit)

  • Windows Server 2012

  • Windows 8 (32-bit or 64-bit)

  • Windows Server 2008 R2

  • Windows 7 (32-bit or 64-bit)

  • Windows Vista (32-bit or 64-bit)

For IP Quality of Service (QoS):

  • For Windows 7 or later client operating systems, or Windows Server 2008 R2 or later server operating systems require the Quality Windows Audio Video Experience (qWAVE) feature. For more information, see Installing qWAVE to Monitor QoS Settings.

  • Windows Vista and Windows Server 2008 (non-R2) do not support setting DSCP bits.

NOTE:To allow VoIP RTP traffic to run on dynamic ports, you must disable the Windows firewall on any computer on which Performance Endpoint software is running.

Compatible network protocol software for RTP, TCP, and UDP

TCP/IP software is provided as part of the network support with all supported versions of Windows.

Quality of Service (QoS) support for TCP/IP is available in all supported versions of Windows that support QoS, except for Windows Vista and Windows Server 2008 (non-R2).

3.1.1 Installing qWAVE to Monitor QoS Settings

For the endpoint to properly monitor QoS settings on a computer running Windows Server 2008 R2 or later server operating systems, you need to install the Quality Windows Audio Video Experience (qWAVE) feature, and the associated service must be running.

The qWAVE feature is enabled by default on computers running Windows 7 and later client operating systems.

To install qWAVE:

  1. Launch the Windows Server Manager.

    NOTE:You can also install qWAVE by running the following at a command prompt:

    servermanagercmd -install qwave

  2. Select Features in the tree on the left, and then select Add Features in the right-hand pane.

  3. From the feature list, select Quality Windows Audio Video Experience.

  4. Click Next, and then click Install.

  5. After the qWAVE installation completes, reboot the server.

3.1.2 Enabling QoS for a Windows Server 2003 or Windows XP Computer

To enable QoS settings on endpoints running Windows Server 2003 or Windows XP, you must add the DisableUserTOSSetting DWORD registry value to each endpoint computer. Add the following DWORD registry value at the endpoints:

HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Services\Tcpip\Parameters\DisableUserTOSSetting = 0

Reboot the endpoint computers after you edit the registry settings.

NOTE:Windows Server 2008 R2 and Windows 7 do not require the DisableUserTOSSetting registry value.
