Real-time Microsoft Teams Phone (PSTN) Events & Bot Joining Calls Automatically

I’m working on a solution to capture real-time events from Microsoft Teams Phone(PSTN Calling), specifically for events like:

Outbound calls

Inbound calls

My goal is not only to capture these events but also to have a bot, built with the Microsoft Bot Framework, join the calls as soon as they start.

Here are a few questions I have:

Capturing Events: What is the best way to retrieve these specific events in real time? I’ve explored the Microsoft Graph API, but I’m uncertain if it provides what I need for Teams Phone (PSTN Calling).

Bot Joining Calls: How can I programmatically have the bot join a call automatically? I’ve read about call automation and using the Graph API for joining calls, but not sure how to get the meeting id of teams phone (pstn) calls real or near real-time.

Any advice or relevant documentation would be really helpful! Thanks!
