This article describes the supported call types in the cloud communications API in Microsoft Graph and how they're used for the signaling process.
Peer-to-peer calls
A call is peer-to-peer (P2P) when one participant is directly calling another participant. If a bot calls a user, and the user is the only calling target specified, this is an example of a P2P call.
If a user wants to call a bot, the bot doesn't need any additional permissions in order to respond to the P2P call. In order for a bot to call a user, it must have the Calls.Initiate.All permission for a P2P call.
Group calls
A group call occurs if there are either three or more participants in the call, or if meeting coordinates were specified when the call was initially created.
You can create a group call through Microsoft Teams, for example.
Currently, bots are able to:
- Create group calls
- Join exisiting group calls
- Invite other participants into an existing group call
- Be invited into existing group calls
