快速入門：管理會議室通話

簡介

在 Azure 通訊服務 （ACS） 會議室通話期間，您可以使用通話 SDK 或通話自動化 SDK 或兩者來管理通話。 在會議室通話中，您可以使用指派給會議室中參與者和屬性的角色來控制通話內動作。 每個參與者允許參與者的角色控制功能，而會議室屬性則套用至整個會議室通話。

呼叫 SDK

通話 SDK 是用戶端通話連結庫，可讓會議室通話中的參與者執行數個通話內作業，例如螢幕共用、開啟/關閉視訊、靜音/取消靜音等等。 如需功能的完整清單，請參閱 呼叫 SDK 概觀。

您可以根據指派給通話參與者的角色來控制功能。 例如，只有演示者可以共享螢幕。 如需參與者角色和許可權，請參閱 會議室概念。

呼叫自動化 SDK

通話自動化 SDK 是一個伺服器端連結庫，可讓系統管理員在中央和控制的環境中管理進行中的會議室通話。 不同於呼叫 SDK，通話自動化 SDK 作業與角色無關。 因此，通話系統管理員可以代表會議室通話參與者執行數個通話內作業。

下列清單描述會議室通話中可用的常見通話內動作。

聯機到會議室通話

通話自動化必須先連線到現有的會議室通話，才能執行任何通話內作業。 CallConnected或 ConnectFailed 事件會使用回呼機制引發，以指出連接作業是否分別成功或失敗。

csharp

Uri callbackUri = new Uri("https://<myendpoint>/Events"); //the callback endpoint where you want to receive subsequent events
CallLocator roomCallLocator = new RoomCallLocator("<RoomId>");
ConnectCallResult response = await client.ConnectAsync(roomCallLocator, callbackUri);

Java

String callbackUri = "https://<myendpoint>/Events"; //the callback endpoint where you want to receive subsequent events
CallLocator roomCallLocator =  new RoomCallLocator("<RoomId>");
ConnectCallResult response = client.connectCall(roomCallLocator, callbackUri).block();

JavaScript

const roomCallLocator = { kind: "roomCallLocator", id: "<RoomId>" };
const callbackUri = "https://<myendpoint>/Events"; // the callback endpoint where you want to receive subsequent events 
const response = await client.connectCall(roomCallLocator, callbackUri);

Python

callback_uri = "https://<myendpoint>/Events"  # the callback endpoint where you want to receive subsequent events
room_call_locator = RoomCallLocator("<room_id>")
call_connection_properties = client.connect_call(call_locator=room_call_locator, callback_url=callback_uri)

成功連線到會議室通話之後， CallConnect 就會透過回呼 URI 通知事件。 您可以使用 callConnectionId ，視需要擷取會議室通話上的通話連線。 下列範例代碼段會使用 callConnectionId 來示範此函式。

新增 PSTN 參與者

使用通話自動化，您可以撥出 PSTN 號碼，並將參與者新增至會議室通話。 不過，您必須設定空間以啟用 PSTN 撥出選項（EnabledPSTNDialout設定為 true），且 Azure 通訊服務 資源必須布建有效的電話號碼。

如需詳細資訊，請參閱 會議室快速入門。

csharp

var callerIdNumber = new PhoneNumberIdentifier("+16044561234"); // This is the ACS-provisioned phone number for the caller  
var callThisPerson = new CallInvite(new PhoneNumberIdentifier("+16041234567"), callerIdNumber); // The target phone number to dial out to
CreateCallResult response = await client.GetCallConnection(callConnectionId).AddParticipantAsync(callThisPerson);

Java

PhoneNumberIdentifier callerIdNumber = new PhoneNumberIdentifier("+16044561234"); // This is the ACS-provisioned phone number for the caller
CallInvite callInvite = new CallInvite(new PhoneNumberIdentifier("+16041234567"), callerIdNumber); // The phone number participant to dial out to
AddParticipantOptions addParticipantOptions = new AddParticipantOptions(callInvite);
Response<AddParticipantResult> addParticipantResultResponse = client.getCallConnectionAsync(callConnectionId)
    .addParticipantWithResponse(addParticipantOptions).block();

JavaScript

const callInvite = {
    targetParticipant: { phoneNumber: "+18008008800" }, // The phone number participant to dial out to
    sourceCallIdNumber: { phoneNumber: "+18888888888" } // This is the ACS-provisioned phone number for the caller
};
const response = await client.getCallConnection(callConnectionId).addParticipant(callInvite);

Python

caller_id_number = PhoneNumberIdentifier(
    "+18888888888"
) # TThis is the ACS-provisioned phone number for the caller
target = PhoneNumberIdentifier("+18008008800"), # The phone number participant to dial out to

call_connection_client = call_automation_client.get_call_connection(
    "call_connection_id"
)
result = call_connection_client.add_participant(
    target,
    operation_context="Your context",
    operationCallbackUrl="<url_endpoint>"
)

拿掉 PSTN 參與者

csharp

var removeThisUser = new PhoneNumberIdentifier("+16044561234");

// Remove a participant from the call with optional parameters
var removeParticipantOptions = new RemoveParticipantOptions(removeThisUser)
{
    OperationContext = "operationContext",
    OperationCallbackUri = new Uri("uri_endpoint"); // Sending event to a non-default endpoint
}

RemoveParticipantsResult result = await client.GetCallConnection(callConnectionId).RemoveParticipantAsync(removeParticipantOptions);

Java

CommunicationIdentifier removeThisUser = new PhoneNumberIdentifier("+16044561234");
RemoveParticipantOptions removeParticipantOptions = new RemoveParticipantOptions(removeThisUser)
                .setOperationContext("<operation_context>")
                .setOperationCallbackUrl("<url_endpoint>");
Response<RemoveParticipantResult> removeParticipantResultResponse = client.getCallConnectionAsync(callConnectionId)
    .removeParticipantWithResponse(removeParticipantOptions);

JavaScript

const removeThisUser = { phoneNumber: "+16044561234" };
const removeParticipantResult = await client.getCallConnection(callConnectionId).removeParticipant(removeThisUser);

Python

remove_this_user = PhoneNumberIdentifier("+16044561234")
call_connection_client = call_automation_client.get_call_connection(
    "call_connection_id"
)
result = call_connection_client.remove_participant(remove_this_user, operation_context="Your context", operationCallbackUrl="<url_endpoint>")

傳送 DTMF

將 DTMF 音調清單傳送給外部參與者。

csharp

var tones = new DtmfTone[] { DtmfTone.One, DtmfTone.Two, DtmfTone.Three, DtmfTone.Pound }; 
var sendDtmfTonesOptions = new SendDtmfTonesOptions(tones, new PhoneNumberIdentifier(calleePhonenumber))
{ 
	OperationContext = "dtmfs-to-ivr" 
}; 

var sendDtmfAsyncResult = await callAutomationClient.GetCallConnection(callConnectionId).GetCallMedia().SendDtmfTonesAsync(sendDtmfTonesOptions);

Java

List<DtmfTone> tones = Arrays.asList(DtmfTone.ONE, DtmfTone.TWO, DtmfTone.THREE, DtmfTone.POUND); 
SendDtmfTonesOptions options = new SendDtmfTonesOptions(tones, new PhoneNumberIdentifier(c2Target)); 
options.setOperationContext("dtmfs-to-ivr"); 
client.getCallConnectionAsync(callConnectionId)
	.getCallMediaAsync() 
	.sendDtmfTonesWithResponse(options) 
	.block(); 

JavaScript

const tones = [DtmfTone.One, DtmfTone.Two, DtmfTone.Three];
const sendDtmfTonesOptions: SendDtmfTonesOptions = {
	operationContext: "dtmfs-to-ivr"
};
const result: SendDtmfTonesResult = await client.getCallConnection(callConnectionId)
	.getCallMedia()
	.sendDtmfTones(tones, {
		phoneNumber: c2Target
	}, sendDtmfTonesOptions);
console.log("sendDtmfTones, result=%s", result);

Python

tones = [DtmfTone.ONE, DtmfTone.TWO, DtmfTone.THREE]
call_connection_client = call_automation_client.get_call_connection(
    "call_connection_id"
)

result = call_connection_client.send_dtmf_tones(
	tones = tones,
	target_participant = PhoneNumberIdentifier(c2_target),
	operation_context = "dtmfs-to-ivr")

通話錄音

Azure 通訊服務 會議室支援通話自動化所提供的錄製功能，包括 start、pausestop、、 resume等。 請參閱下列代碼段，以在會議室通話中啟動/停止/暫停/繼續錄製。 如需動作的完整清單，請參閱 通話自動化錄製。

csharp

// Start recording
StartRecordingOptions recordingOptions = new StartRecordingOptions(new ServerCallLocator("<ServerCallId>"))
{
   RecordingContent = RecordingContent.Audio,
   RecordingChannel = RecordingChannel.Unmixed,
   RecordingFormat = RecordingFormat.Wav,
   RecordingStateCallbackUri = new Uri("<CallbackUri>"),
   RecordingStorage = RecordingStorage.CreateAzureBlobContainerRecordingStorage(new Uri("<YOUR_STORAGE_CONTAINER_URL>"))
};
Response<RecordingStateResult> response = await callAutomationClient.GetCallRecording()
.StartAsync(recordingOptions);

// Pause recording using recordingId received in response of start recording.
var pauseRecording = await callAutomationClient.GetCallRecording ().PauseAsync(recordingId);

// Resume recording using recordingId received in response of start recording.
var resumeRecording = await callAutomationClient.GetCallRecording().ResumeAsync(recordingId);

// Stop recording using recordingId received in response of start recording.
var stopRecording = await callAutomationClient.GetCallRecording().StopAsync(recordingId);

Java

// Start recording
StartRecordingOptions recordingOptions = new StartRecordingOptions(new ServerCallLocator("<serverCallId>"))
                    .setRecordingChannel(RecordingChannel.UNMIXED)
                    .setRecordingFormat(RecordingFormat.WAV)
                    .setRecordingContent(RecordingContent.AUDIO)
                    .setRecordingStateCallbackUrl("<recordingStateCallbackUrl>");

Response<RecordingStateResult> response = callAutomationClient.getCallRecording()
.startWithResponse(recordingOptions, null);

// Pause recording using recordingId received in response of start recording
Response<Void> response = callAutomationClient.getCallRecording()
              .pauseWithResponse(recordingId, null);

// Resume recording using recordingId received in response of start recording
Response<Void> response = callAutomationClient.getCallRecording()
               .resumeWithResponse(recordingId, null);

// Stop recording using recordingId received in response of start recording
Response<Void> response = callAutomationClient.getCallRecording()
               .stopWithResponse(recordingId, null);

JavaScript

// Start recording
var locator: CallLocator = { id: "<ServerCallId>", kind: "serverCallLocator" };

var options: StartRecordingOptions =
{
  callLocator: locator,
  recordingContent: "audio",
  recordingChannel:"unmixed",
  recordingFormat: "wav",
  recordingStateCallbackEndpointUrl: "<CallbackUri>"
};
var response = await callAutomationClient.getCallRecording().start(options);

// Pause recording using recordingId received in response of start recording
var pauseRecording = await callAutomationClient.getCallRecording().pause(recordingId);

// Resume recording using recordingId received in response of start recording.
var resumeRecording = await callAutomationClient.getCallRecording().resume(recordingId);

// Stop recording using recordingId received in response of start recording
var stopRecording = await callAutomationClient.getCallRecording().stop(recordingId);

Python

# Start recording
response = call_automation_client.start_recording(call_locator=ServerCallLocator(server_call_id),
            recording_content_type = RecordingContent.Audio,
            recording_channel_type = RecordingChannel.Unmixed,
            recording_format_type = RecordingFormat.Wav,
            recording_state_callback_url = "<CallbackUri>")

# Pause recording using recording_id received in response of start recording
pause_recording = call_automation_client.pause_recording(recording_id = recording_id)

# Resume recording using recording_id received in response of start recording
resume_recording = call_automation_client.resume_recording(recording_id = recording_id)

# Stop recording using recording_id received in response of start recording
stop_recording = call_automation_client.stop_recording(recording_id = recording_id)

終止呼叫

您可以使用通話自動化 SDK 掛斷動作來終止通話。 當掛斷動作完成時，SDK 會 CallDisconnected 發佈事件。

csharp

_ = await client.GetCallConnection(callConnectionId).HangUpAsync(forEveryone: true); 

Java

Response<Void> response = client.getCallConnectionAsync(callConnectionId).hangUpWithResponse(true).block();

JavaScript

await callConnection.hangUp(true);

Python

call_connection_client = call_automation_client.get_call_connection(
    "call_connection_id"
)

call_connection_client.hang_up(is_for_everyone=True)
