Finally I was able to do some testing with the Citrix Lync optimization pack and off course installing was not a problem but when logging on Lync within XenApp the following error occurred."Citrix HDX RealTime Connector for Microsoft Lync was unable to sign in."
After retyping my username and password the Services Sign In was still not able to sign in.
When viewing the status in of the Citrix HDX RealTime Connector for Microsoft Lync in the Lync client, this is done by clicking on Audio Video Settings the service was not registered.
In the next screen print the status is Registered but it was not before I added some registry keys.
To get the Citrix HDX RealTime Connector to registred correctly the following registry keys were added.
If you look good to the Lync client there is a difference how to start an audio or video call.
When one of the above is selected there will be an other screen what is part of the Citrix HDX solution.
Here you can see that Citrix is actually handling the call. Also when there is an inbound call in XenApp session the Toast is slightly different form the normal Lync client.
When Video is used this is actually video from the local client which is displayed in the ICA session just like it's done with flash offloading.
When you tried to capture the screen it will be a screen dump without the video content.
This picture is taken with my phone.
I think Citrix has done some good work because with this pack it is possible to have audio and video within Citrix XenApp. Audio and video were not bad at all but I haven't tested with a lot of users and not when the system is used in a production environment.
