Citrix® HDX™ RealTime Optimization Pack for Microsoft® Lync® version 2010 provides a highly scalable solution for delivering real-time audio-video conferencing and VoIP enterprise telephony through Microsoft® Lync® in XenDesktop, XenApp, and VDI-in-a-Box environments. HDX RealTime Optimization Pack leverages your existing Microsoft® Lync® infrastructure and inter-operates with other Microsoft® Lync® endpoints running natively on devices.

HDX RealTime Optimization Pack consists of both client and server components:

  • The client component, called Citrix HDX RealTime Media Engine, is integrated with the Citrix Receiver on the endpoint device and performs all signaling and media processing directly on the user device itself, offloading the server for maximum scalability, minimizing network bandwidth consumption and ensuring optimal audio-video quality.
  • The server-side (and virtual desktop) component, Citrix HDX RealTime Connector, is a connector to the Microsoft Lync client that drives the RealTime Media Engine on the endpoint. The RealTime Connector runs in the virtual server environment alongside Microsoft Lync and communicates signaling information over a Citrix ICA virtual channel to the RealTime Media Engine running on the user device.

What's new in version 1.4.100

  • We've added support for Microsoft Lync Online / Office 365 hosted Lync for those of you who maintain your user accounts in the cloud (typically SMB customers). Please note that AD Federation is not currently supported.

Issues fixed in version 1.4.100

  • We've reduced the delay in starting audio calls with participants outside your firewall.
  • Your users can now switch between terminals connecting to the same XenDesktop without having to restart RealTime Connector. [#14039]

What's new in version 1.4

  • We've added support for the Meet Now feature of Microsoft Lync. Your users can join a meeting through optimized voice and video or by phone.
  • We've added support for LogiTech C920 cameras for Windows and Linux Ubuntu desktops and HP ThinOS on HP terminals.

    When using a LogiTech C920 camera with the Optimization Pack, the CPU on the terminal sending the video doesn't limit the video resolution of the camera. The terminal can send up to HD (720P) video to the other parties in the call (depending on the codec used in the call, the processor speed of the recipient, and the network restrictions set by the Lync administrator).

Issues fixed in version 1.4

  • On Macs when you disconnect from XenDesktop while on a call, your call hangs up, just like on Windows and Linux. [#14005]
  • If you want your location and Single Sign on (SSO) information to be used in your authentication process for logons, you must enable the save password feature. [#15878]
  • You and your call participant can now both go on and off hold simultaneously without any adverse effects. [#16269]
