MS Teams call user API

Question

Partner organization would like to migrate from stationary phones to MS Teams. MS Teams would serve as virtual phone. They would like to receive calls from users outside group. Somebody call on department number, middleware choose user, call it in MS Teams and transfer connection.
I was searching in API docs, but I found only chat messages (also sender must be defined...)
https://learn.microsoft.com/en-us/graph/api/channel-post-messages?view=graph-rest-1.0
Is it possible, to do this in MS Teams?

Answer 1

Hi MarekDrzewiecki-8400！

I also searched Teams API document but only found this link shows call resource API:

https://learn.microsoft.com/en-us/graph/api/resources/call?view=graph-rest-beta

Besides, Luca also provides a good way to receive calls from users outside group by create Teams Phone System.

If you want to create phone system in MS Teams, please refer to:

Hi,
you have to setup Teams Phone System, either via Direct Routing or via Calling Plan
