I want to use callto to initiate video calls on Teams.
Something like:
<a href="callto:[email protected]">start call</a>
This worked at first, but after about 3 calls it switched to always popping up a "Calling disabled by your administrator" message.
I am the administrator, and there appears to be nothing in the Team admin portal to govern this.
A support call to Microsoft ended with them insisting this was a bug on my end and not an issue with Teams.
What am I doing wrong?
