Skype for Business with MediaEngine produce High Jitter Values from the Client to the MediationServer


Roland Scheck

Question

Hello,

We have the Problem when a User starts a Phone Call to an external Attendee over Skype with Media Connector installed on the Citrix Terminal Server that the Call have High Jitter Values from the Client to the Mediation Server.

User have Win10, MediaEngine 2.3 and Citrix Receiver 4.10

The User connects to a shared Desktop (Windows Server 2012R2), VDA Version 7.11 and Media Connector 2.3. Media Connector state is optimized.

 

We have try to Update the MediaEngine on both side to 2.7, update the VDA to 7.15Cu3 and then to 1811.1, but the Problem persist.

 

We also try to install a new Citrix Terminal Server with an attach Hard Disk for c: (for the other Terminal Server we use PVS), on this new Server we only install Office with Skype, try different VDA Agents and Media Connectors, but as long as the Media Connector is installed we have this Issue. No Virus Scanner is installed on this Server.

 

Hypervisor is vmware. Also try to set on the VM the “Latency Sensitivity” to High, but with no success to change this behavior.

 

Did anyone have similar Problems or know why this happen?

 

Thanks

There is a known issue with reported high jitter values reported in QOE reports with RTOP. The issue is resolved in 2.8 release which is due in a few weeks. Remember this is a pure aesthetic issue in reports, it does not affect performance. Open a case and reference me. I will send you the fix for verification - to make sure this is the issue you are facing.
