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,
As an alternate solution, I am using teams via Web which works perfectly fine with same ISP.
I think the issues is with using app with certain ISP and that is strange. If I can work with web then why cant MS update or propose any settings that can resolve this issue.

Thanks and Regards,

Viren

Hi Viren, I have been troubleshooting with Dodo. Do you happen to have a TP-Link Deco Mesh Wifi network? Cheers, Daryl.

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.
