When screen sharing people see black screen
Hi Viren_Manek;
Believe is ISP related.
Change the QoS setting in Teams fixed the problems for us.
Your tenant admin needs to change this:
Teams Admin> Meetings > Meeting Settings > Network
Turn off -> Insert Quality of Service (QoS) markers for real-time media traffic
Also update Teams client to the latest version.
Log-out and log back in.
Restart your Teams app.
You may need to wait for the change to kick in.
Good luck.
Regards
Tenny
I logged a case with Dodo on 28/5 & follow it up with them weekly. I have been advised they are aware of the issue & their escalation support team is working on a resolution with Microsoft and other ISPs also affected. No eta when it will be resolved sorry.
The only 'fix' is to change ISP which I can't do as I live in a rural area & Optus/Dodo/I-Primus etc are the only ones available. I just keep hot spotting my mobile when I need to share my screen & once the session has started reconnect to my home wifi which seems to keep the port opened & I can keep sharing. If I stop sharing the port closes & I have to go back through hotspotting phone.
