Azure Bot that joins Microsoft Teams Call and transfers speech to text using Azure Speech Service

Question

I configured Azure Bot which is configured to join Microsoft Teams calls, and calling endpoint is provided. Now using .NET I have implementation for calling endpoint and also the speech service starts converting speech to text when the call is answered. But the issue is that this works right now with my Microphone, the audio is not going through team's call (no audio configuration for speech service). How I can achieve that the audio to go from teams to my server not from my microphone to the server.. I was going through the documentation, but it didn't help much..
