Integrate Microsoft Teams Audio calls in my application

[Larry88]

Hello All

We have an android application, I want to Integrate Teams Audio calls in my application.

This is our user case: Customer use android application at reception desk, to call staff via MS Team service.

Function require detail:

- List all user of Microsoft Teams in the application

- Choose a user and make a call to user inside the application

Do the MS Team have any API help us do that? If yes, could give us document about it? If no, is there any special service MS Team for Microsoft Partner?

I look forward to your response.

Thank you so much.

@Larry88 - You can create a call using API. You can list all the members using Teams Roaster and please check this Create call API to create a call with user.

Thanks,

Nikitha.

Hi Nikita,

I have the same requirement as integration with MS Teams to make a Call. I checked your reference link "Create call API"(https://docs.microsoft.com/en-us/graph/api/application-post-calls?view=graph-rest-1.0&tabs=http), but the document describes it just work for the bot.
In case I have a web application, have anyway to make a call to MS Teams?

I look forward to your response
Thanks

Hi Nikita,
From reading the document you attached I understand that in a 1:1 call I have to call the bot and have the bot call the person in the MS teams again, is that right?
