Citrix Optimization Pack 1.3 for Microsoft Lync 2010

Citrix have released a new version of Optimization Pack 1.3 for Microsoft Lync 2010

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 Optimization Pack 1.3 for MS Lync 2010

  • We’ve added two authentication methods: TLS-DSK and Kerberos.
  • We’ve simplified logon so your users aren’t prompted for credentials as often.
  • We’ve added menu options to Microsoft Outlook and as Smart Tags in other Microsoft Office applications:
    • Start a Call
    • Start a Video Call
