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

WM1 No luck with Optus. They blamed my router. My only solution was to use the browser based version of teams when working from home and I had no issues.

My Teams Windows App worked fine when I was NOT connected to Dodo NBN FTN. I moved to Internode and the problem went away. Dodo later reported that they had fixed the problem but I had moved off by then.

VPN does not work, have tried multiple times. I'm glad optus has escalated, honestly I just gave up.

I had even tried VPNs to get around it and the problem remained.
