The HDX RealTime Optimization Pack (RTOP) for Skype® for Business is a feature of Citrix Virtual Apps and Desktops (formerly XenApp and XenDesktop), Advanced (formerly Enterprise) and Premium (formerly Platinum) editions. HDX RTOP provides optimized delivery of the Microsoft Skype for Business 2015, 2016 and 2019 clients.
HDX RTOP’s support and maintenance is tied to the lifecycle of the underlying Citrix Virtual Apps and Desktops (XenApp and XenDesktop) product in use.
HDX RTOP LTSR is compatible and supported with all actively supported Citrix Virtual Apps and Desktops (XenApp and XenDesktop) LTSRs and CRs. Please refer to the Citrix Product Lifecycle (Product Matrix) for details.
HDX RTOP is supported only on server and client Operating System versions that are supported by their manufacturer and only with Skype for Business versions that Microsoft still supports under mainstream or extended support.
1. Long Term Service Release
HDX RTOP 2.4 is a Long Term Service Release (LTSR). The EoM/EoL lifecycle of Optimization Pack 2.4 aligns with the lifecycle of the Citrix Receiver for Windows 4.9 LTSR.
Code-level maintenance (critical defect and security fixes) is provided by updating to the most recent RTOP Cumulative Update software version.
CUs are released twice a year, aligned with the XenApp/XenDesktop CUs in April and October.
The components covered under the LTSR program are:
- HDX RealTime Connector for Skype for Business
- HDX RealTime Media Engine for Windows only
HDX RealTime Media Engine for Mac, Linux, Android and Workspace Hub are not included in the LTSR program
Lifecycle Phases: GA (General Availability), EOM (End of Maintenance), EOL (End of Life). For definitions of these terms, click here.
Customers must be current with Citrix Customer Success Services (CSS) for Citrix Virtual Apps and Desktops to obtain HDX RealTime Connector LTSRs and LTSR Cumulative Updates (CUs).
Accessing and Deploying Updates: Cumulative Updates (CUs) are software releases that provide maintenance corrections and/or fixes. CUs will be available for download from www.citrix.com for Customer Success Services (Software Maintenance) customers.
Generally, CUs will include fixes and no new functionality. CUs are cumulative in nature, so any new CU will include all fixes released in previous CUs for that component.
This means that all updates will include all previous updates. You will not be able to install a subset of the fixes included in a CU release.
Support is available for any LTSR version level, but code level maintenance will be provided on the latest released CU.
Admins that want to routinely point their end users to the latest version may choose to advertise a download page for the latest current release version or a download page for the latest LTSR CU version (only the RTME for Windows is covered by the LTSR program). Those pages will be evergreen – the URLs will persist while the contents on the pages are refreshed with each release. If you prefer to point your end users to a specific version, choose one of the pages listed here.
