使用voximplant的DialogFlow和上下文

Question

我尝试使用这里描述的Voximplant集成在DialogFlow中设置上下文：https://cogint.ai/voximplant-dialogflow-connector-2019/#settingcontexts

require(Modules.AI);
const languageCode = "en-US";
const agentId = 247;
let agent,
  call,
  conversation,
  endUserParticipant,
  isConversationCreated = false,
  isCallCreated = false,
  isCallConnected = false,
  isParticipantCreated = false;


VoxEngine.addEventListener(AppEvents.Started, 

function (ev) {
  agent = new CCAI.Agent(agentId);
  agent.addEventListener(CCAI.Events.Agent.Started, () => {
    conversation = new CCAI.Conversation({ agent: agent });
    conversation.addEventListener(CCAI.Events.Conversation.Created, () => {
      isConversationCreated = true;
      createParticipant();
    });
  });
});


VoxEngine.addEventListener(AppEvents.CallAlerting, 

function (ev) {
  isCallCreated = true;
  createParticipant();
  call = ev.call;
  call.answer();
  call.addEventListener(CallEvents.Connected, 
  
  function () {
    isCallConnected = true;
    //Script whith phone number to contexts must be added here somehow. Probably in setupMedia function.
    setupMedia();
  });
  
  call.addEventListener(CallEvents.Disconnected, 
  
  function () {
    conversation.stop();
    VoxEngine.terminate();
  });
});


function createParticipant() {
  if (!isConversationCreated || !isCallCreated) return;
  endUserParticipant = conversation.addParticipant({
    call: call,
    options: { role: "END_USER" },
    dialogflowSettings: {
      lang: languageCode,
      singleUtterance: true,
      replyAudioConfig: { audioEncoding: "OUTPUT_AUDIO_ENCODING_OGG_OPUS" },
    },
  });
  endUserParticipant.addEventListener(CCAI.Events.Participant.Created, () => {
    isParticipantCreated = true;
    setupMedia();
  });
}


function setupMedia() {
  if (!isParticipantCreated || !isCallConnected) return;
  endUserParticipant.analyzeContent({
    eventInput: { name: "WELCOME", languageCode: languageCode },
  });
  endUserParticipant.addEventListener(

//Script whith phone number to contexts must be added here somehow.
 phoneContext = {
        name: "phone",
        lifespanCount: 99,
        parameters: {
            caller_id: call.callerid(),
            called_number: call.number()
        }
    },
    //endUserParticipant.setQueryParameters({contexts: [phoneContext]})
//Script whith phone number to contexts must be added here somehow.
    CCAI.Events.Participant.PlaybackFinished,
    () => {
      
//Added by and call works, but hang up      
      VoxEngine.setQueryParameters({contexts: [phoneContext]});
//Added by and call works, but hang up

      VoxEngine.sendMediaBetween(call, endUserParticipant);
    }
  );
  VoxEngine.sendMediaBetween(call, endUserParticipant);
}

Voximplant号码被转发到Dialogflow，但在20秒后，voicebot变得静默，但呼叫没有终止。我去掉了上下文部分，call和voicebot就可以正常工作了。

怎么啦？

Answer 1

我推荐使用Voximplant的Modules.AI集成，而不是您在cogint.ai文章中使用的Modules.CCAI。Modules.CCAI是通过Dialogflow的一键式集成自动使用的，但除了我所看到的以外，它还没有得到很好的支持。

他们有该here的说明和演练视频here。不幸的是，它的应用编程接口与CCAI模块有很大的不同，但是你会找到更多的参考资料和例子(就像我在cogint.ai上看到的)。

Modules.AI仅适用于对话流ES。

Answer 2

我最终重写了我的代码。我能够通过脚本将caller_id / caller_number参数传递给DialogFlow，而不是作为上下文。但是，我在我的欢迎意图中添加了这两个变量作为上下文。

function setupMedia() {
  if (!isParticipantCreated || !isCallConnected) return;
  endUserParticipant.analyzeContent({
    eventInput: { 
                  name: "WELCOME", 
                  languageCode: languageCode, 
                  parameters: {
                                      //phone: call.callerid(),
                                      caller_id: call.callerid(),
                                      called_number: call.number()}
              },
  });
  endUserParticipant.addEventListener(
    CCAI.Events.Participant.PlaybackFinished,
    () => {
      VoxEngine.sendMediaBetween(call, endUserParticipant);
    }
  );
  VoxEngine.sendMediaBetween(call, endUserParticipant);
}
