因为我是SIP的新手，所以无法理解它。请帮助我。

我已经下载了Android SDK中提供的示例项目“SipDemo”，但由于显示“注册失败”，因此无法理解。请检查设置'

Android代码如下：

WalkieTalkieActivity.java 

import android.app.Activity;
import android.app.AlertDialog;
import android.app.Dialog;
import android.app.PendingIntent;
import android.content.DialogInterface;
import android.content.Intent;

import android.content.SharedPreferences;
import android.os.Bundle;
import android.preference.PreferenceManager;
import android.util.Log;
import android.view.*;
import android.net.sip.*;
import android.widget.EditText;
import android.widget.TextView;
import android.widget.ToggleButton;
import java.text.ParseException;

public class WalkieTalkieActivity extends Activity implements

    pushToTalkButton.setOnTouchListener(this);
