使用 Amazon Chime SDK PSTN 音訊服務結束通話 - Amazon Chime SDK

您可以使用 CreateSipMediaApplicationCall API 來結束外撥通話。API 會叫用指定 SIP 媒體應用程式 ID 的端點。客戶可以透過將動作傳回至 SIP 媒體應用程式來控制呼叫的流程。

如果成功回應，API 會傳回 202 http 狀態碼與 transactionId，您可以搭配 UpdateSipMediaApplicationCall API 使用來更新進行中呼叫。

下圖顯示對傳出呼叫的 AWS Lambda 函數端點發出的呼叫。

叫用 CreateSipMediaApplicationCall API 時的資料流程。當外撥通話的狀態變更時，API 會叫用不同的端點。

針對 SIP 媒體應用程式設定的端點會針對撥出呼叫的不同狀態叫用。當客戶和呼叫時，Amazon Chime SDK 會使用HANGUP呼叫事件類型叫用端點。

此範例顯示的典型調用事件HANGUP。
