I am a developer wanting to build an application to obtain the phone number from an (unanswered) inbound call on Teams in order to query a customer database for prior orders, etc., and open a window showing that data to the user receiving the incoming call.

After a lot of online searching, I learned that it is possible to obtain the incoming phone number using call records, but this will NOT work for me because call records are only created after the call ends.

My question is: Is it possible, through the Graph API or some other method, to extract the phone number from an incoming call on Teams in real-time (or as close as possible) and pass that data to an application that can do something with it?
