SIP註冊失敗

Question

我遇到了SIP API的問題。我按照d.android.com的指南，從sip2sip.info獲得一個免費的SIP帳戶來測試我的應用程序。 更新：我試過ekiga.net，而且我自己也設置了一個Kamailio服務器，但是這些也沒有幫助。

每當我嘗試註冊我的配置文件時，都會失敗並顯示錯誤消息「0」。以下是代碼：

package com.mysys.mysip; 

import java.text.ParseException; 

import android.net.sip.SipException; 
import android.net.sip.SipManager; 
import android.net.sip.SipProfile;

import android.view.View.OnClickListener; 
import android.widget.Button; 
import android.widget.TextView; 

public class MainActivity extends Activity { 
    public SipManager mSipManager = null; 
    public SipProfile mSipProfile = null; 

    @Override 
    public void onCreate(Bundle savedInstanceState) { 
     super.onCreate(savedInstanceState); 
     setContentView(R.layout.activity_main); 

     if (mSipManager == null) { 
      mSipManager = SipManager.newInstance(this); 
     } 

     Button connectButton = (Button) findViewById(R.id.buttonConnect); 
     connectButton.setOnClickListener(new OnClickListener() { 
      @Override 
      public void onClick(View v) { 
       buildProfile(); 
       if (mSipProfile != null) { 
        openProfile(); 
       } 
      } 
     }); 
    } 

    public void buildProfile() { 
     try { 
      SipProfile.Builder builder = new SipProfile.Builder("censored", "sip2sip.info"); 
      builder.setPassword("censored"); 
      mSipProfile = builder.build(); 
     } catch (ParseException e) { 
      Log.e("SipProfile.Builder", "Parse error!"); 
      e.printStackTrace(); 
     } 
    } 

    public void openProfile() { 
     Intent intent = new Intent(); 
     intent.setAction("com.mysys.sip.INCOMING_CALL"); 
     PendingIntent pendingIntent = PendingIntent.getBroadcast(this, 0, intent, Intent.FILL_IN_DATA); 

     SipRegistrationListener listener = new SipRegistrationListener() { 
      @Override 
      public void onRegistering(String localProfileUri) { 
       Log.i("SIP Registration", "Registering."); 
       updateStatus("Registering..."); 
      } 

      @Override 
      public void onRegistrationDone(String localProfileUri, long expiryTime) { 
       Log.i("SIP Registration", "Done!"); 
       updateStatus("Registered! Yay!"); 
      } 

      @Override 
      public void onRegistrationFailed(String localProfileUri, int errorCode, String errorMessage) { 
       Log.e("SIP Registration", "Failed! URI: " + localProfileUri + " Reason: " + errorMessage); 
       updateStatus("Registration failed."); 
      } 
     }; 

     try { 
      mSipManager.open(mSipProfile, pendingIntent, null); 
      mSipManager.setRegistrationListener(mSipProfile.getUriString(), listener); 
     } catch (SipException e) { 
      e.printStackTrace(); 
     } 
    } 

    public void updateStatus(final String status) { 
     this.runOnUiThread(new Runnable() { 
      public void run() { 
       TextView statusView = (TextView) findViewById(R.id.textViewStatus); 
       statusView.setText(status); 
      } 
     }); 
    } 

    @Override 
    public boolean onCreateOptionsMenu(Menu menu) { 
     getMenuInflater().inflate(R.menu.activity_main, menu); 
     return true; 
    } 

    @Override 
    public boolean onOptionsItemSelected(MenuItem item) { 
     switch (item.getItemId()) { 
      case R.id.menu_settings: 
       Intent intent = new Intent(this, SettingsActivity.class); 
       startActivity(intent); 
     } 
     return super.onOptionsItemSelected(item); 
    } 
} 

與Android SDK自己的演示相比，我查了兩次代碼，但沒有發現任何東西。我在查詢之前也進行了搜索，唯一相關的是我發現將協議設置爲TCP，但它並未解決我的問題。

Answer 1

你檢查以下功能是否返回true：

isVoipSupported()和isApiSupprted()。同時檢查您的SIP帳戶是否正常工作。

Answer 2

你可以嘗試onther免費服務抿像https://www.linphone.org/eng/linphone/register-a-linphone-account.html並對其進行測試，它爲我工作通過SIP帳戶Linphone中

Answer 3

builder.setPort(5060); 
builder.setProtocol("TCP"); 
builder.setOutboundProxy("proxy.sipthor.net"); 
me = builder.build();
