[…] nobody uses SIP…

Say what?

In my part of the world signaling for literally every phone call, be it mobile or fixed, traverses networks and operators using SIP.

Had to scroll way too far for this.

Luckily, I’ve been able to get away with only using Teams for meetings, so my exposure is limited, but last time I messed around in the top right corner there was an area that indicated it would show notifications from other accounts.

I have had no need or desire to test this, though.

Apparently the dumpster fire known as MS Teams supports multiple accounts now.
