呼叫概述Calls overview

Microsoft Graph 中的云通信 Api 为您的应用程序和服务通过各种通信相关功能(如呼叫和联机会议)与用户进行交互的方式添加了一个新的维度。The cloud communications APIs in Microsoft Graph add a new dimension to how your apps and services interact with users through various communications related features, such as calls and online meetings. 本文介绍了受支持的呼叫类型以及它们如何用于信号流程。This article describes the supported call types and how they're used for the signaling process.

对等呼叫Peer-to-peer calls

当一个参与者直接呼叫另一个参与者时,呼叫为对等(P2P)。A call is peer-to-peer (P2P) when one participant is directly calling another participant. 如果机器人呼叫用户,并且用户是指定的唯一呼叫目标,则这是 P2P 呼叫的一个示例。If a bot calls a user, and the user is the only calling target specified, this is an example of a P2P call.

P2P 调用关系图

如果用户想要呼叫机器人,bot 不需要任何其他权限即可响应 P2P 呼叫。If a user wants to call a bot, the bot doesn't need any additional permissions in order to respond to the P2P call. 为了使 bot 能够呼叫用户,它必须具有调用。 Initiate。 P2P 呼叫的所有权限。In order for a bot to call a user, it must have the Calls.Initiate.All permission for a P2P call.

组调用Group calls

如果呼叫中有三个或更多参与者,或者在最初创建呼叫时指定了会议坐标,则会发生组调用。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.

例如,您可以通过 Microsoft 团队创建组呼叫。You can create a group call through Microsoft Teams, for example.

分组调用关系图

目前,bot 能够:Currently, bots are able to:

  • 创建组调用Create group calls
  • 加入现有的组调用Join exisiting group calls
  • 邀请其他参与者加入现有的组呼叫Invite other participants into an existing group call
  • 被邀请加入现有的组调用Be invited into existing group calls
