Hi,
I've only seen a couple of mentions of QOS with softphone but nothing really for remote access so i'm not sure if it's possible though I know in the hosted Mitel solution there is some detail on it -
https://oneview.mitel.com/s/article/Implementing-QoS-on-Windows-EnvironmentsWe have found intermittent phone quality issues for users and I'm just exploring possible ways to improve it.
One of them is to switch from using BLAST as the connection protocol to PCOIP and the other was to try some QOS settings to prioritise voice.
We are running MiCollab 7.3 client on VmWare Horizon 7.8
