获取 Microsoft Teams 的当前通话状态

Question

On my Windows PC, I've installed the Microsoft Teams app. I'd like to find out with an appropriate API whether I'm actually in a call and whether my microphone within a call is muted or not.

So my questions are:

1. How can I find out whether I'm currently in a call?
2. What is the current microphone state within a call (muted / unmuted)?

A little bit of background: I want to implement a little .NET Core service that polls for these information in the background.

Answer 1

1. You can get user status using Graph API presence request, in response body you will get status.

   GET https://graph.microsoft.com/v1.0/me/presence

Response:

HTTP/1.1 200 OK
Content-Type: application/json
Content-Length: 1574

{  
    "id": "fa8bf3dc-eca7-46b7-bad1-db199b62afc3",
    "availability": "Available",
    "activity": "Available"
}

2. To know current microphone state within a call (muted / unmuted) is not possible.

There is a get participant API to get microphone state but for this you need to create a calling bot in teams, create a call in that bot and then from created call using call ID you can get participant microphone state using GET https://graph.microsoft.com/v1.0/communications/calls/{id}/participants/{id}
