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.

Hi Daryl,
No, I haven't contacted Dodo and also I do not have TP-Link Deco Mesh Wifi.
I have Dodo HG659 Home Gateway Modem.
Is this to do with Modem?

Tx,

Great.
This worked for me.

I had to ask Admin to update the settings and it took around 2 hours to get this impact.

Thank you very much.
