使用NIST JAIN SIP API发送SIP请求时出错

Question

我试图使用NIST的JAIN SIP API实现发送REGISTER SIP请求。

首先我给我SipController类的数据成员的声明：

private int port; 
private long cseq = Math.abs(numberGenerator.nextInt()); 
private MessageFactory messageFactory; 
private AddressFactory addressFactory; 
private HeaderFactory headerFactory; 
private SipStack sipStack; 
private SipProvider sipProvider; 

，这里是发送请求的代码：

public void register(String aor,String serverAddress) throws ParseException,InvalidArgumentException,SipException 
    { 
     Address addressOfRecordObj = addressFactory.createAddress(aor); 
     ArrayList<ViaHeader> viaHeaders = new ArrayList<ViaHeader>(1); 
     try 
     { 
      viaHeaders.add(headerFactory.createViaHeader(InetAddress.getLocalHost().getHostAddress(),port,"udp",getNewBranch())); 
     } 
     catch (UnknownHostException e) 
     { 
      e.printStackTrace(); 
     } 
     Request request = messageFactory.createRequest( 
       ....addressFactory.createURI(serverAddress), 
       ...."REGISTER",sipProvider.getNewCallId(), 
       ....headerFactory.createCSeqHeader(cseq++,"REGISTER"), 
       ....headerFactory.createFromHeader(addressOfRecordObj,Integer.toString(Math.abs(numberGenerator.nextInt()))), 
       ....headerFactory.createToHeader(addressOfRecordObj,null), 
       ....viaHeaders, 
       ....headerFactory.createMaxForwardsHeader(70)); 
     request.addHeader(headerFactory.createContactHeader(addressFactory.createAddress("sip:127.0.0.1:"+port))); 
     log(">> "+request); 
     sipProvider.sendRequest(request); 
} 

我打电话使用语句

这种方法

sipController.register("sip:user@domain.com","sip:127.0.0.1:5061"); 

数据成员端口的值为5060.

我想要做的是发送请求到我的计算机上运行的另一个应用程序，它正在侦听端口5061.此应用程序是我发送请求的同一程序的另一个实例。

当我调用SipProvider类的sendRequest（）方法时，我得到一个javax.sip.SipException异常，并显示消息“发送请求时发生IO异常”。此异常包含一个java.net.BindException，其原因是消息“无法分配请求的地址：数据报发送失败”。

这里是堆栈跟踪：

在我做错了任何想法？

为了记录，我已经解决了这个问题。 这是一段时间以前，所以我不记得确切是什么错，但显然我使用了一个错误的.jar文件的NIST实现。
