呼叫：应答

  • 项目

命名空间：microsoft.graph

重要

Microsoft Graph /beta 版本下的 API 可能会发生更改。 不支持在生产应用程序中使用这些 API。 若要确定 API 是否在 v1.0 中可用，请使用 版本 选择器。

启用机器人以接听来 电。 传入呼叫请求可以是来自组呼叫或对等呼叫中的参与者的邀请。 如果收到群组呼叫邀请，通知将包含 chatInfo 和 meetingInfo 参数。

机器人应在呼叫超时前接听、 拒绝 或 重定向 呼叫。当前超时值为 15 秒。 常规方案的当前超时值为 15 秒，基于策略的录制方案为 5 秒。

此 API 可用于以下国家级云部署。

权限

为此 API 选择标记为最低特权的权限。 只有在应用需要它时，才使用更高的特权权限。 有关委派权限和应用程序权限的详细信息，请参阅权限类型。 要了解有关这些权限的详细信息，请参阅 权限参考。

权限类型 最低特权权限 更高特权权限
委派（工作或学校帐户） 不支持。 不支持。
委派（个人 Microsoft 帐户） 不支持。 不支持。
应用程序 Calls.JoinGroupCall.All Calls.JoinGroupCallAsGuest.All

注意： 对于使用应用程序托管媒体的调用，还需要 Calls.AccessMedia.All 权限。 必须至少具有以下权限之一才能确保 source 对传入呼叫通知中的 解密：Calls.AccessMedia.All、Calls.Initiate.All、Calls.InitiateGroupCall.All、Calls.JoinGroupCall.All、Calls.JoinGroupCall.All、Calls.JoinGroupCallAsGuest.All。 source是传入呼叫通知中的呼叫者信息。 如果没有其中至少一个权限，将 source 保持加密状态。

HTTP 请求

POST /app/calls/{id}/answer
POST /communications/calls/{id}/answer

注意：/app 路径已弃用。 今后将使用 /communications 路径。

请求标头

名称 说明
Authorization 持有者 {token}。 必填。 详细了解 身份验证和授权。
Content-type application/json. 必需。

请求正文

在请求正文中，提供具有以下参数的 JSON 对象。

参数 类型 说明
callbackUri String 允许机器人为并发调用提供特定的回调 URI，以便接收以后的通知。 如果尚未设置此属性，则改用机器人的全局回调 URI。 这必须是 https。
acceptedModalities 字符串集合 接受模式的列表。 可取值为：audio、video、videoBasedScreenSharing。 需要用于接听呼叫。
callOptions incomingCallOptions 调用选项。
mediaConfig appHostedMediaConfig 或 serviceHostedMediaConfig 媒体配置。 必需。
participantCapacity Int 对于 基于 Teams 策略的录制 方案，应用程序可以处理呼叫的参与者数。

示例 3：应答基于策略的录音呼叫

在 基于策略的录制方案中，在策略下的参与者加入呼叫之前，传入呼叫通知将发送到与策略关联的机器人。 可以在 botData 属性下找到联接信息。 然后，机器人可以选择接听呼叫并相应地 更新录制状态 。

在请求中指定Answer基于策略的录制通知时participantCpapacity，属于同一策略组的后续参与者加入事件将作为参与者JoiningNotification而不是新的传入呼叫通知发送，直到当前呼叫实例正在处理的参与者数达到 中指定的participantCapacity数字。

下面是在这种情况下机器人将接收的传入呼叫通知的示例。
