Hello RobertoGomez,

  1. Start a scheduled meeting automatically
    This is not directly supported through Teams APIs. While a calling/meeting bot can programmatically join a scheduled meeting, there is no supported API to automatically press the Teams Room "Join" button or start a meeting UI without user interaction.

  2. Automatically answer an incoming call in a meeting room
    Not supported through general Teams APIs. Auto-answer is available only for certain Teams-certified devices (such as Teams Rooms and Teams phones) through device configuration and policies, rather than via Teams API calls.

  3. Add participants to an ongoing call or meeting
    Yes, supported. Microsoft Graph Cloud Communications APIs allow applications or bots to invite additional participants to an active call or meeting using the participant invite API.
