# 初始化
#### 应用场景
在座席侧使用Openeye软电话接口进行注册话机号码时，需要完成组件初始化。
#### 前提条件
1. 已经完成WebDemo的下载。
2. 已经安装Openeye的本地程序包，并且OpenEye的本地程序已经启动。
3. 已经完成param.js中服务器等信息的配置。
 
#### 流程说明

Demo中代码路径：WebDemo\\js\\OpenEye_SDK.js。
1. [初始化SDK](https://support.huaweicloud.com/devg-openeye-cec/cec_05_1517.html)。

   打开webdemo页面，会收到OpenEye返回的消息，只有收到onOpeneyeLoginReady后才能调用OpeneyeLogin下的接口，只有收到onOpeneyeCallReady后才能调用OpeneyeCall下的接口。
   ```
   function initOpeneye(){  
       if (global_openEye_SDK== null)  
       {  
          global_openEye_SDK = new OpenEye_SDK({
   onOpeneyeDeamonReady: onOpeneyeDeamonReady,
   onOpeneyeDeamonClose: onOpeneyeDeamonClose,
   serviceStartUp: serviceStartUp,
   serviceShutDown: serviceShutDown,
   onOpeneyeLoginReady: onOpeneyeLoginReady,
   onOpeneyeLoginClose: onOpeneyeLoginClose,
   onOpeneyeCallReady: onOpeneyeCallReady,
   onOpeneyeCallClose: onOpeneyeCallClose,
   onVersionInfoNotify : onVersionInfoNotify
   });
       }  
   }  
   function onVersionInfoNotify(data)  
   {  
       writeLog("version is " + data.param.version);  
   }  
   function onOpeneyeDeamonReady() {  
       writeLog("OpenEye Deamon is Ready");  
   }  
   function onOpeneyeDeamonClose() {  
       writeLog("OpenEye Deamon is Closed, please restart OpenEye Deamon it.");  
       global_openEye_SDK= null;  
   }  
   function serviceStartUp() {  
       writeLog("Openeye Service StartUp");  
   }  
   function serviceShutDown() {  
       writeLog("Openeye Service is shutdown, please restart it.");  
   }  
   function onOpeneyeLoginReady(){  
       writeLog("onOpeneyeLoginReady");  
   }  
   function onOpeneyeLoginClose(){  
       writeLog("onOpeneyeLoginClose");  
   }  
   function onOpeneyeCallClose() {  
       writeLog("onOpeneyeCallClose");  
   }  
   function onOpeneyeCallReady() {  
       writeLog("onOpeneyeCallReady");
   }
   ```
   
   
2. 初始化OpenEyeCall的参数和监听呼叫事件。 
   ```
   function initOpeneyeCall(localIp)  
   {  
       console.info("onOpeneyeCallReady");
       initOpeneyeCall();
   }
   ```
   - 调用[setBasicCallEvent](https://support.huaweicloud.com/devg-openeye-cec/cec_05_1531.html)接口监听的OpenEyeCall的呼叫事件。
     ```
     function initOpeneyeCall()  
     {  
         global_openEye_SDK.openEyeCall.setBasicCallEvent({  
             onCallIncoming: onCallIncoming,
             onCallOutGoing: onCallOutGoing,
             onCallRingBack: onCallRingBack,
             onCallConnected: onCallConnected,
             onCallEnded: onCallEnded,
             onCallEndedFailed: onCallEndedFailed,
             onCallRtpCreated: onCallRtpCreated,
     onCallOpenVideoReq: onCallOpenVideoReq
         });  
     }
     ```
     
   
   - 调用[config](https://support.huaweicloud.com/devg-openeye-cec/cec_05_1518.html)接口设置OpenEyeCall的SIP服务器信息。
     ![](https://support.huaweicloud.com/devg-openeye-cec/public_sys-resources/note_3.0-zh-cn.png)
     必须保证SIP服务器的信息填写正确，否则无法进行账号注册
     ```
     function sipBasicCfg() {
         global_cloudIPCC_SDK.openEyeCall.config({
             networkInfo: {
                 serverAddr: GlobalSipIp,
                 sipServerPort: GlobalSipPort,
                 sipTransportMode: 0,
                 httpPort: 0
             },
         }, {response: configResponse});
     }
     function configResponse(data)
     {
         if (data.result == 0) {
             writeLog("Set OpenEyeCall Sip Config Success.");
             register();
         } else {
             writeLog("Set OpenEyeCall Sip Config Failed.");
         }
     }
     ```
