Purpose of this document
This document serves as a guide to prepare an IT organization for incorporating Unified Communications (UC) into desktop and application virtualization environments. Microsoft Skype for Business,
standard “must have” application for desktop users. In years past, it was acceptable to use Lync for chat and presence only. However today, 90 of the Fortune 100 companies are running Microsoft Skype for Business for media rich video calling, voice calling, conferencing, and screen sharing. Over 100 million people are using Skype for Business to communicate for work, as of March 2015. 79% of U.S. enterprise customers use or plan to use Skype for Business for telephony, according to Microsoft. Skype for Business is now the leader in PBX sales for enterprises of more than 400 lines and #3 PBX in America. Over 75% of surveyed customers have budget for Unified Communications. More over 3 out of 4 Citrix customers adopting UC have chosen Skype for Business. Without proper consideration and design for optimization, virtual desktop and application users will very likely find the Microsoft Skype for Business experience to be subpar. Citrix and Microsoft both provide technologies to optimize this experience, to make Skype for Business responsive with crisp video and audio, even when working remotely in a virtual desktop. However, with multiple combinations of Skype for Business infrastructures, clients, endpoint types, and user locations one must find the right “recipe” to deliver Skype for Business optimally. The Citrix® HDX™ RealTime Optimization Pack for Microsoft® Skype for Business®
offers clear, crisp high-definition video calls an optimized architecture. Users can seamlessly participate in audio- video or audio-only calls to and from other Skype for Business users, Optimization Pack users and other standards-based video desktop and conference room systems. Please note that – as of HDX RealTime Optimization Pack 2.0 we support Microsoft Skype for Business Server 2015 and the Skype for Business 2015 client in its native UI. Support for Skype for Business 2016 is currently being worked on. This document is meant to guide architects and administrators in choosing the right Skype for Business delivery solution for their Citrix environment.

Optimized versus Generic delivery of Microsoft Skype for Business
This is often what causes the most confusion about delivering a Microsoft Skype for Business experience in a Citrix environment. Most Citrix administrators are well aware of how the ICA protocol, a key element of Citrix’s HDX (high definition experience) software stack works. ICA is made up of many virtual channels that allow the end user to interact with and receive content from the server host. Among these are the most common, an interactive video display such as Thinwire (which offers an h.264-enhanced supercodec), bi-directional audio, and webcam video compression to deliver a webcam experience. While there are a lot of tuning options to deliver a reasonably good experience in this manner (see CTX133024 ), it is usually not the most optimal method for delivering Skype for Business. The main reason is that the media must “hairpin” from your client to the server in the data center and then back to the endpoint. This can put significant load on the server (especially for video) and can cause delay and an overall degraded experience, especially if the other party in a Skype for Business call is originating from a user in a similar virtualized experience. This method for delivering a Microsoft Skype for Business experience is referred to as “Generic” delivery. The preferred method of delivery is the “Optimized” method. In this case the architect and/or administrator chooses to deploy either a Citrix or Microsoft optimization solution. The “Optimized” method is basically like splitting the Skype for Business client in two, as illustrated in the following comparison diagram. The user interface lives inside the virtual host, and is seen completely in the virtual desktop or application display. However, the media rendering, or media engine is separated off to run on the endpoint. This allows for a very rich rendering of the audio and video experience.

Choosing the right Skype for Business optimization for your environment Skype for Business (SfB) optimization is not a “one size fits all” technology. You must consider your Skype for Business environment and the endpoints users will be using. A recommended solution for each scenario is outlined in the following matrix. Additionally this document offers greater detail on the pros/cons and things that must be considered for each optimization or delivery technology.
Windows 1 Macintosh 2 Linux 3 Chrome/HTML5 Android iOS SfB 2015 Server / SfB 2015 client on host
Lync 2013 Server/Lync 2013 client on host*

Thin PC 2 - Macintosh client versions supported: OS X 10.7 through 10.11 3 - Linux Client versions supported: Red Hat Enterprise 6.2, Ubuntu 14.04, 12.04 and 10.04, Suse Enterprise SP1, SP2 & SP3, HP ThinPro, Unicorn eLux RP 4.3.0 (only 32-bit versions are supported.) Dell Wyse ThinOS 8.2 is currently supported only on Linux RTME 1.8
It should be noted that optimization packs have not been developed yet for mobile OS’s. Typically mobile users who desire access to Skype for Business on their devices will leverage Skype for Business native apps from the appropriate app store. The new release of the HDX RealTime Optimization Pack, version 2.0 supports optimized delivery of the Skype for Business 2015 client to Linux, Mac and Windows devices.
Whenever possible, best practice is to use an optimized architecture for delivering Skype for Business to end users. Pros of using HDX RealTime Optimization Pack for Skype for Business
• Richest experience, all media rendered on endpoint • No hair-pinning effect, media communications go point to point between clients • Less resource impact on the XenApp/XenDesktop hosts • Less ICA bandwidth consumed over “generic” approach • Allows for use of high tech Skype for Business optimized headsets and handsets • Supports delivery with XenApp using Windows Server OS’s • Simple installation on client devices, minimal prerequisites • Can be used remotely from the enterprise network in conjunction with Skype for Business Edge Services (users making Citrix connections via NetScaler Gateway) • Wide choice of supported thin client devices (see list at : http://docs.citrix.com/en-us/hdx- optimization/2-0/hdx-realtime-optimization-pack-system-requirements.html )
• Support provided by both Microsoft and Citrix support • Supported method for delivering Skype for Business 2015 as seamless app from XenApp • No requirement for both the sides of the optimized architecture to authenticate to the backend • Requires no modification to the Skype for Business server back end

Upgrading from RealTime Optimization Pack 1.8 to 2.0
The update process for the pieces are as follows: 1. On each of the Windows guest operating systems, you will need to uninstall the Citrix HDX RealTime Connector ver 1.8 before installing the Citrix HDX RealTime Connector ver 2.0 2. On each of the client machines the Citrix HDX RealTime Media Engine must be upgraded to 2.0 at the same time. The Citrix HDX RealTime Connector 2.0 cannot be used with Citrix HDX RealTime Media Engine 1.8.
Your users may sometimes arrive at a situation where they don’t get the desired status, connection type and mode as shown above. Here are a few ways to resolve the issues they may face: 1. Citrix HDX RealTime Connector systray shows status as Un-optimized.
HDX RealTime Media Engine on the client machine. Ensure the VDA has the HDX RealTime Connector installed and the client endpoint has the Media Engine installed on it.

Page 25
Resolution – It is strongly recommended that your users use the Skype for Business UI in conjunction with Citrix HDX RealTime Optimization Pack, as the UI integration and testing has been conducted with the latest version. The issue can be resolved by running the following command on your Lync 2013 server. For more information follow this link .
Set-CsClientPolicy -Identity Global -EnableSkypeUI $true
Then restart the Lync Server Front-‐End service on your Lync servers.
4. Citrix HDX RealTime Connector is not seen in the systray of the session, even after the Skype for Business Client has been launched within the VDA. Resolution – this issue occurs if the VDA doesn’t have the required Skype for Business update as described in the KB3114351 installed in it.

Bandwidth consumption with the HDX RealTime Optimization Pack is consistent with native Skype for Business. Bandwidth guidelines: http://technet.microsoft.com/en-us/library/gg615029(v=ocs.14).aspx
http://technet.microsoft.com/en-us/library/jj688118.aspx The HDX RealTime Media Engine will obey bandwidth restrictions configured on the SfB/Lync server, applying them to both RT Video and H.264. If the customer already provisioned their network for "fat desktop" Skype for Business / Lync users with voice and video conferencing, the Optimization Pack will work with that bandwidth as it adds very little network overhead; the only additional traffic is the low bandwidth virtual channel control interactions between the RTC on the VDA and the RTME on the user device.

How does the HDX RTOP support Quality-of-Service (QoS)?
It is possible to configure alternate UDP ports for audio and video to manage QOS. Port ranges are configured with a server-side policy on the Lync server, using the Set-CsConferencingConfiguration cmdlet:
https://technet.microsoft.com/en-us/library/gg412969.aspx (reference) https://technet.microsoft.com/en-us/library/jj204760%28v=ocs.15%29.aspx (examples of usage)
ClientAudioPort/ClientAudioPortRange/ClientVideoPort/ClientVideoPortRange.
If using Office 365 / Skype for Business Online, use remote administrative access to manage these parameters, as described here: http://blog.schertz.name/2015/04/managing-lync-online-with-powershell/ (high level overview) https://technet.microsoft.com/ja-jp/library/dn362831%28v=ocs.15%29.aspx (detailed documentation)
Citrix RealTime Optimization Pack 1.8 supported only the legacy parameters ClientMediaPort and ClientMediaPortRange. It was possible to configure the port range for media, but not possible to configure separate port ranges for audio and video.
The RTOP also supports DSCP marking for media packets. This provides another solution for QoS. For Windows this is possible by pushing out QoS policies to the endpoints. For Linux and Mac OS X, we provide registry settings that need to be applied in the user’s profile on the server.
http://support.citrix.com/article/CTX201116 (may need minor updating for 2.0)
The HDX RTME uses Microsoft Edge servers only for media connectivity, i.e. to obtain ICE candidates using STUN and TURN protocols during call setup, and to relay media streams if direct connectivity is not possible. In the v2 architecture, SIP signaling is handled exclusively by the Skype for Business client on XenApp/XenDesktop.

Microsoft Lync VDI 2013 plugin
This is a v1 approach from Microsoft aimed at avoiding the “hairpinning” effect and offloading the media rich Skype for Business functions to the endpoint. This method was suggested by Microsoft to be used for Lync access in a VDI scenario before the Citrix Real Time Optimization Pack 2.0 was released. It is now a Microsoft recommended best practice to use the RTOP 2.0 over the Microsoft plugin in all environments.
It is important to note that Microsoft Lync VDI 2013 plugin only supports Windows client endpoints. Unlike Citrix optimization packs there is no support for Macintosh or Linux clients. Furthermore the list of Windows OS’s supported is limited. ( Source ) These include:
Windows Embedded Standard 7 with SP1, Windows 7 with SP1, Windows 8, Windows 8.1 Embedded and Windows 10 Embedded
Additionally there are fewer supported options for Skype for Business delivery with the Microsoft Lync VDI 2013 plugin. VDI delivery from Windows Workstation hosts are fully supported from Microsoft. Delivery from XenApp using Windows Server 2008R2 published desktops does work successfully, and is supported by Citrix. However, this method is not supported by Microsoft. Additionally publishing Skype for Business seamlessly on XenApp does not work with the Microsoft Lync VDI 2013 plugin. The Microsoft Lync VDI 2013 plugin is supported in the following Citrix environments:
XenDesktop 5.6 with Windows 7 VDA’s for delivery XenDesktop 7.x with Windows 7 or 8.1 VDA’s for delivery XenDesktop/XenApp 7.x with Windows Server 2008R2 VDA’s for delivery* XenApp 6.x with Windows Server 2008R2 VDA’s for delivery*
*server based desktop delivery supported by Citrix but not by Microsoft
The installation and configuration procedures are as follows: 1. Ensure a supported Citrix Receiver is installed on each endpoint device. 2. Download the Microsoft Lync VDI Plugin directly from Microsoft. You will need to choose the 32 bit version for a Citrix environment. 3. Install the Microsoft VDI Plugin on all client machines that will use Lync optimization and that meet the Windows OS prerequisites stated above. 4. A Lync Server certificate must be installed on each user device as well as on the desktop hosts.
Delivering Microsoft Skype for Business to XenApp and XenDesktop Users
Page 29
5. On Lync Server 2013, ensure that EnableMediaRedirection is set to $True for all VDI users. (see screen shot below) After connecting, one can quickly confirm that optimization is working. If it is possible to connect directly with the VDI desktop using RDP it is recommended to try this first to confirm pairing. However, if one tests with RDP, the bitness of the RDP client must be 32 bit to match the version of the Microsoft Lync VDI 2013 plugin. Obviously testing can be done directly with the Citrix Receiver. However, it is common to test with RDP when troubleshooting errors, pairing issues, or in support exercises with Microsoft. Once connected you should see the icons at the bottom of the Lync 2013 UI to change slightly and show that pairing is complete.
If pairing does not complete for some reason the icon on the lower left will indicate no audio devices are available by issuing an exclamation icon warning. It is also common for the icon on the lower right to blink during the pairing process. If it disappears completely, pairing was unsuccessful and optimized Lync calls will not occur.
The Generic HDX RealTime technologies for media-over-ICA provide a valuable fallback when optimized delivery of the Skype for Business client is not possible. Over the years, Citrix has introduced numerous HDX technologies to deliver a good user experience when this approach is used, such as:
•
• Webcam Video Compression (300-‐600 Kbps) • UDP/RTP Audio transport (resilient to network congestion and packet loss) Delivering Microsoft Skype for Business to XenApp and XenDesktop Users
Page 30
• Adaptive Display (video quality and frame rate self-‐adjust to the network) • Multi-‐stream ICA with packet tagging (DSCP and WMM) for QoS • Jitter buffering and echo cancellation in Citrix Receiver for Windows • Audio plug-‐n-‐play • Audio device routing (e.g. ringtone to speakers, audio to headset)

Local App Access, a platinum edition feature, seamlessly integrates users' locally installed Windows applications into a hosted desktop environment without changing from one computer to another.
With Local App Access, you can: • Access applications installed locally on a physical laptop, PC, or other device directly from their virtual desktop. Provide a flexible application delivery solution. If users have local applications that you cannot virtualize or that IT does not maintain, those applications still behave as though they are installed on a virtual desktop. • Eliminate double-‐hop latency when applications are hosted separately from the virtual desktop by putting the shortcut to the published application on the user's Windows device.
With the feature parity that we have achieved with RTOP 2.0, there are but a couple of features that necessitate the usage of the Local App Access. The 2 features are gallery view & client-side recording.
If you wish to make access of Skype for Business running on the client endpoint available for the users in the Citrix HDX session, you must enable the Local App Access feature, which is not enabled by default in the hosting and client environment. Delivering Microsoft Skype for Business to XenApp and XenDesktop Users
Page 31
There are two modes to enable the feature – Published Shortcuts or Published Application
Local App Access – Published Shortcuts
The entire set of shortcuts on the user’s desktop will be made available in the Citrix HDX session. Ensure that the Skype for Business shortcut is available on the user’s desktop.
The biggest challenge in delivering Skype for Business using Local App Access is that the Skype for Business client should co-reside with the Outlook client. Since in a XenApp/XenDesktop environment it is generally not desirable to install Office on the user device, this usually means configuring either a second instance of the Skype for Business client on the XenApp/XenDesktop server or an instance of the Outlook client on the user device.
Another limitation is with app sharing. While desktop sharing works fine when the Skype for Business client is delivered using Local App Access, app sharing does not work when the app is running on a different machine (i.e. not on the user device).
Follow the below steps to enable the Local App Access feature: On the Desktop Delivery Controller, open Studio and select Policies in the left pane and select Create Policy in the Actions pan on the right.
