Citrix recommends that you deliver the Lync client using generic HDX RealTime technologies, Local App Access, or Microsoft Lync 2013 VDI Plug-in if your users need the following features that are not supported by HDX RealTime Optimization Pack for Lync. For more information, see Delivering Microsoft Lync to XenApp and XenDesktop Users.
For a feature matrix of alternative methods of delivering the Lync client from XenApp and XenDesktop, see http://support.citrix.com/article/CTX200279.
Caution: Editing the registry incorrectly can cause serious problems that may require you to reinstall your operating system. Citrix cannot guarantee that problems resulting from the incorrect use of Registry Editor can be solved. Use Registry Editor at your own risk. Be sure to back up the registry before you edit it.
- The dialpad is not supported with the Lync 2010 client.
- The HDX RealTime Connector for Lync 2013 installer does not support Lync when installed using the Office 365 Click-to-Run.
- Lync basic is not supported by the RealTime Connector. Workaround: Use the full version of Lync.
- Response groups is not supported.
- Delegation is not supported.
- Voicemail access and playback is not supported. Use Microsoft Outlook to view, access, and playback voicemail messages.
- Recording is not supported. Citrix recommends evaluating third-party server-based recording solutions.
- Gallery view is not supported in multiparty calls. Active speaker view is used in Lync multiparty calls using Optimization Pack.
- There are no Call and Video Call buttons in the Lync Contact Card.
- On Linux terminals, the RealTime Media Engine installer disables multimedia redirection in Linux Receiver. This avoids Optimization Pack and Linux/Unix Receiver getting into a conflict when accessing video devices. However, this means that other Unified Communications applications cannot work with Generic USB redirection when accessed on a Linux terminal that has RealTime Media Engine installed.
- The date and time strings on USB telephone devices with display capabilities are not properly localized.
- The Lync dial pad and Lync dial-in bar do not support mnemonic dialing (for example, 1800CALLATT).
- The Optimization Pack disables the use of hardware accelerated H.264 video using the Logitech C920 camera to prevent an issue with bad video. To use hardware acceleration with the Logitech C920 create or modify the following registry key:
On 32-bit Windows:
Data: 0 (enables the hardware acceleration);
On 64-bit Windows:
Data: 0 (enables the hardware acceleration)
