无法使用twilio可编程语音呼叫客户

Question

我正在建立一个系统，该系统将对从端点生成的客户端进行呼叫，但是在发起呼叫时，只会使状态排队并且不会响铃。

exports.capabilityToken = functions.https.onRequest((request, response) => {
    const capability = new ClientCapability({
        accountSid: accountSid,
        authToken: authToken,
      });
      capability.addScope(new ClientCapability.IncomingClientScope(request.query.identity));
      const appSid = "APXXXXXXXXXXX";
      capability.addScope(
        new ClientCapability.OutgoingClientScope({ applicationSid: appSid })
      );
      const token = capability.toJwt();

      response.set('Content-Type', 'application/jwt');
      response.send(token);
 });

 exports.accessToken = functions.https.onRequest((request, response) => {
    console.log("tokenated");
    var identity = null;
    if (request.method == 'POST') {
      identity = request.body.identity;
    } else {
      identity = request.query.identity;
      console.log(request.query.identity);
    }  


    // Used when generating any kind of tokens
    const accountSid = "ACXXXXXXXX";
    const apiKey = "SKXXXXXX";
    const apiSecret = "XXXXXXX";

    // Used specifically for creating Voice tokens
    const pushCredSid = "CRXXXXXXXXX";
    const outgoingApplicationSid = "APXXXXXXXXX";

    // Create an access token which we will sign and return to the client,
    // containing the grant we just created
    const voiceGrant = new VoiceGrant({
        outgoingApplicationSid: outgoingApplicationSid,
        pushCredentialSid: pushCredSid
      });

    // Create an access token which we will sign and return to the client,
    // containing the grant we just created
    const token = new AccessToken(accountSid, apiKey, apiSecret);
    token.addGrant(voiceGrant);
    token.identity = identity;
    token.clientName = identity;
    latestToken = 'Token:' + token + " >>>>>>>>>>  @ " + moment().format('hh:mm a');
    console.log(latestToken);
    response.send(token.toJwt());
});

我只是使用Dial.client拨打电话，然后设置了我的身份，但实际上并没有拨打电话，而是显示了此输出。

{ accountSid: 'ACXXXX',
  annotation: null,
  answeredBy: null,
  apiVersion: '2010-04-01',
  callerName: null,
  dateCreated: null,
  dateUpdated: null,
  direction: 'outbound-api',
  duration: null,
  endTime: null,
  forwardedFrom: null,
  from: '+8628XXXXX',
  fromFormatted: '+86XXXXX',
  groupSid: null,
  parentCallSid: null,
  phoneNumberSid: null,
  price: null,
  priceUnit: 'USD',
  sid: 'CAXXXXXX',
  startTime: null,
  status: 'queued'
}
