为什么在发送REGISTER消息时删除P-Charging-Vector报头？

Question

我尝试向I-CSCF发送REGISTER消息，如下所示。P-Charging-Vector header被添加到消息中，您可以在下面的日志中看到。我检查了发送出去的数据包，但此报头已被删除。它似乎被在SipServletRequestImpl.send()之后运行的代码删除了。另一个问题与其中的orig-ioi参数有关。它被设置为orig-ioi="Type“，但是正如您在下面的1cscf@homedomain.com消息中看到的那样，引号被删除了。

你对这个问题有什么想法吗？它是已知的错误还是限制？

代码如下：

sipFactory = (SipFactory) envCtx.lookup("sip/wae-base-sipt/SipFactory");
SipApplicationSession appSession = sipFactory.createApplicationSession();
SipServletRequest req = sipFactory.createRequest(appSession, "REGISTER",   "bob@yahoo.com", "bob@yahoo.com");
String icid = java.util.UUID.randomUUID().toString();
req.addHeader("P-Charging-Vector", "icid-value" + "=\"" + icid + "@47.168.150.25\";" +"orig-ioi=\"Type 1cscf@homedomain.com\"");

它的输出：

使用1.2.167版本的jain-sip-ri创建PChargingVector头部。

String val1 = "icid-value=\"218ace3d-12e7-4eb6-87a2-0bc7a744743d@47.168.150.25\";orig-ioi=\"1cscf@homedomain.com\"";
Header header1 =  SipFactory.getInstance().createHeaderFactory().createHeader("P-Charging-Vector", val1);            
System.out.println(header1.toString());

输出：

P-Charging-Vector: icid-value="218ace3d-12e7-4eb6-87a2-0bc7a744743d@47.168.150.25";orig-ioi=1cscf@homedomain.com

提前感谢

JSIP不喜欢在第二个参数前后缺少引号。要传递的标头应如下所示：

P-Charging-Vector: icid-value="18234_1374589491316@27.14.152.1";orig-ioi="Type 1cscf@homedomain.com"

我不确定它是否是正式需要的，但JSIP需要它。我可以看一看，等我有更多的时间再修。
