When I start a call in Teams my user status is set to "busy-inacall" and as I have set "busy-on-busy" in the Teams admin policies, I am not available for a call anymore. When I'm in a call and a planned meeting in Outlook starts the user status is set to "busy-inAmeeting" and I'm still not available for a call anymore. When I'm not in a call and a planned meeting in Outlook starts, I am set to "busy-inAmeeting" as well but I'm available for a call.
So the user status/presence does not display the availability for a call. How can I get (via MS Graph) if is user is available for a call?
