sip заголовок авторизации не может быть добавлен

Question

У меня вопрос об аутентификации с jain sip library. Я использую jain sip для регистрации учетных записей sip на сервере Asterisk. Как только я пытаюсь добавить AuthorizationHeader следующее сообщение об ошибке появляется:

The method makeAuthHeader(HeaderFactory, Response, Request, String, String) is undefined for the type Utils

Вот фрагмент кода:

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

Кажется, что может не метод makeAuthHeader() не может быть найден.

Код SipClientServiceImpl.java:

Answer 1

Ну, Utils не является частью API, и у него просто нет метода, который вы пытаетесь использовать. Лучший способ сделать клиент авторизацию, чтобы использовать пример из https://svn.java.net/svn/jsip~svn/trunk/src/examples/authorization/ShootistAuth.java

Это соответствующая часть:

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++; 
      } 

Answer 2

Класс Utils не принадлежит этот метод, как вы можете увидеть здесь: http://grepcode.com/file/repo1.maven.org/maven2/javax.sip/jain-sip-ri/1.2.203/gov/nist/javax/sip/Utils.java Вы должны использовать что-то другое, но я не могу найти ничего о том, что класс/метод для использования.
