On a WAN connection, audio quality depends on the latency, packet loss, and jitter on the connection. You can use voice chat over both LAN and WAN connections. This low latency codec is ideal for voice communications. The bandwidth consumption with this codec is approximately 56 Kbps (28 kilobits per second in each direction). This codec was introduced in the Citrix Receiver for Windows’ 11.2 online plug-in and in the 11.100 Citrix Receiver for Linux. If the audio functionality is a separate USB device, you can redirect the audio separately using Bidirectional Audio.Ĭonfigure Bidirectional Audio to use the Optimized-for-Speech audio codec (also known as Medium Quality). In a general scenario, separate plug-in webcams have the audio and video USB functions combined, but laptop or integrated devices are often (but not always) separate devices. If you use the microphone in the webcam, note that there are two types of webcams ones where the audio device is part of the webcam device and others where the audio device (USB logical arrangement) appears separately. To use speakers and a microphone, you must use version 12.x or above of the Citrix Receiver’s online plug-in for Windows, because you require the echo cancellation feature introduced in that release. Citrix recommends using a good quality headset with noise and echo cancellation. Even if the webcam being used has a built-in microphone, it is generally best to use a headset with a microphone to avoid picking up ambient noise and generating echoes in the audio. This approach minimizes bandwidth consumption. If using a headset, it is generally best to send the audio over the Bidirectional Audio virtual channel (CTXCAM, “Client Audio Mapping”) instead of using USB Redirection (CTXGUSB). If using a USB telephone on the LAN, then isochronous USB redirection over the CTXGUSB “Generic USB” virtual channel is recommended because both signaling and audio are involved. The HDX Monitor should be used to confirm the configuration settings in effect. The following configuration guidelines for XenDesktop can improve the user experience when using voice chat and/or video chat with Lync.

Refer to the Knowledge Center article CTX124655 ‑ Best Practice: How to Configure XenApp 6 Voice and Video Chat Features for Microsoft Office Communicator 2007 R2 for information on using XenApp 6 to deliver Microsoft Office Communicator.
The article is split into two sections the first section deals with any configuration changes required to the XenDesktop 5.x environment and the second section looks at Microsoft Lync itself. This article describes how to get the best results from both products in these scenarios.
The user can view the video conference and participate in the conversation but does not use a webcam. The user might choose to join in a video conference as a voice-only participant. Video conferencing as an observer (voice-only participant) It enables users to chat in real time using a headset or USB telephone connected to their computer or thin client. This feature of Lync is much like using a telephone. There are three scenarios where HDX RealTime is used with Lync: Citrix XenDesktop with HDX RealTime allows the users to communicate using the voice chat and video chat features of Microsoft Lync.
Microsoft Lync is a unified communications client used with Microsoft Lync Server that provides instant messaging, voice chat, and desktop video conferencing.
This article provides guidelines for configuring XenDesktop 5.x to deliver Microsoft Lync (formerly Microsoft Office Communicator).
