Java 无法添加sip授权标头

我对jain sip库的身份验证有疑问。我正在使用jain sip向Asterisk服务器注册sip帐户。 当我尝试添加

AuthorizationHeader

时，出现以下错误消息：

类型Utils的方法makeAuthHeader（HeaderFactory、Response、Request、String、String）未定义

以下是代码片段：

AuthorizationHeader authHeader = Utils.makeAuthHeader(
                headerFactory, response, request, userId, password);
        request.addHeader(authHeader);

似乎找不到方法
makeAuthHeader（）

代码SipClientServiceImpl.java：

任何建议都将不胜感激

谢谢大家!
 类Utils不拥有此方法，您可以在此处看到：
你必须使用一些不同的东西，但我找不到关于使用什么类/方法的任何信息。
好吧，Utils不是API的一部分，它根本没有你试图使用的方法。进行客户端身份验证的最佳方法是使用

这是相关部分：

if (response.getStatusCode() == Response.PROXY_AUTHENTICATION_REQUIRED
                    || response.getStatusCode() == Response.UNAUTHORIZED) {
                AuthenticationHelper authenticationHelper = 
                    ((SipStackExt) sipStack).getAuthenticationHelper(new AccountManagerImpl(), headerFactory);

                inviteTid = authenticationHelper.handleChallenge(response, tid, sipProvider, 5);

                inviteTid.sendRequest();

                invco++;
            }

很难说到底发生了什么，因为Utils并不是真正的API。这个例子应该对您有所帮助。否则发布完整的代码和日志，感谢您的回复！我注意到了。这就是在这里发布问题的原因：）谢谢你的回答我是否需要在
public void processResponse中添加以下代码（ResponseEvent ResponseEvent
方法？出于某种原因，即使在执行代码段中的步骤后，它也不允许我进行注册。：/很可能是的。但这取决于情况。如果您正在进行注册，请确保调整代码，使其注册事务，而不是INVITE。下面的行似乎是问题所在
inviteTid=authenticationHelper.handleChallenge（响应，tid，sipProvider，5，false）；
It trows SIPException tid为空。您应该在客户端事务的上下文中发送请求以获取非空tid，但即使这样，也有更可靠的方法来实现。使用类似的方法可以使ClientTransaction ct=sipProvider.getNewClientTransaction（yourRegisterRequest）；ct.sendRequest（）工作；
