我正在尝试将传出的 sip 请求发送到另一台服务器，但该请求只是路由回我的服务器。我需要通过 UDP 发送请求。我正在使用 MOBIENTS Sip Servlet。

这是日志：

Here's my DAR config:

ALL:("RestComm", "DAR:From", "NEUTRAL", "", "NO_ROUTE", "0")
INVITE:("org.mobicents.servlet.sip.example.CallBlockingApplication", "DAR:From", "ORIGINATING", "", "NO_ROUTE", "0")
REGISTER:("RestComm", "DAR:From", "NEUTRAL", "", "NO_ROUTE", "0")
MESSAGE:("SmsReceiver", "DAR:TO", "ORIGINATING", "", "NO_ROUTE", "0", "DIRECTION=OUTBOUND")

Here's my code (using HttpServlet) that sends the message:

    public void doGet(HttpServletRequest request, HttpServletResponse response) {
            SipFactory sf = (SipFactory) getServletContext().getAttribute(
                            "javax.servlet.sip.SipFactory");

            SipApplicationSession appSession = ((ConvergedHttpSession) request
                            .getSession()).getApplicationSession();

            logger.info("sipfactory= " + sf);
            logger.info("appSession=" + appSession);

            try {
                    SipServletRequest sipRequest = sf.createRequest(appSession, "MESSAGE","sip:1404xxxxxxx8@216.27.87.216",
                                    "sip:63917xxxxxxx@216.27.87.216");


                   //the uri where I want to send my message
                    SipURI uri = sf.createSipURI("1404xxxxxxx", "sms-proxy-01.bandwidthclec.com");
                    uri.setPort(5060);                                                

                    sipRequest.setRequestURI(uri);


                   //message content
                    sipRequest.setContent("foo-bar", "text/plain");
                    logger.info("sipRequest= " + sipRequest);
                    sipRequest.send();
            } catch (ServletParseException e) {
                    // TODO Auto-generated catch block
                    e.printStackTrace();
            } catch (UnsupportedEncodingException e) {
                    // TODO Auto-generated catch block
                    e.printStackTrace();
            } catch (IOException e) {
                    // TODO Auto-generated catch block
                    e.printStackTrace();
            }

    }

任何帮助/建议都会很棒。

提前致谢。
