Setting up the RealTime Multimedia Engine (RTME)

connector

This section describes how to install and use Lync or Skype for Business (SFB) on a Citrix desktop.

1 Install Citrix HDX RealTime Connector on Citrix desktop VDA/Server.

NOTE:

• HDX RealTime Multimedia Engine is the package installed on ThinOS; it is HDX RealTime Connector that needs to be installed

or upgraded on the remote server and VDA.

• The Upgrade option from 1.7 to 1.8 is discussed at Docs.citrix.com/en-us/hdx-optimization/1-8/upgrade-1-7-to-1-8.html.

• The Firewall conguration is required on remote server and VDA. For more information, refer to Docs.citrix.com/en-us/hdx-

optimization/1-8/hdx-realtime-optimization-pack-congure-rewall.html.

• To know about the technical overview of RTME 2.1, go to Docs.citrix.com/en-us/hdx-optimization/2-1/hdx-realtime-

optimization-pack-overview.

IMPORTANT: The RTME 1.8 feature on ThinOS supports only HDX RealTime Connector 1.8 due to Citrix limitation.

2 Update the ThinOS rmware, and install the RTME.i386.pkg on the ThinOS client. For information about installing the RTME package,

see Installing the RTME package on ThinOS.

IMPORTANT

: In ThinOS 8.3.1 HF release and ThinOS 8.3.2 release, the RTME 1.8 and 2.1 co-exist in the release package,

supporting both versions of RTME connectors.

3 (This step is for RTME 1.8 only) Congure the Domain Name Server (DNS) settings on ThinOS for Lync Server.

NOTE

: You must ensure that the thin client does not have USB redirection for video/audio devices in order to have RTME

working correctly.

4 Log in to your Citrix Desktop, and sign in to Lync client or Skype for Business (SFB) client.

• For RTME 1.8, the RTME icon is displayed in the lower-left corner of the Lync client window.
