Dear Sir

            we use mobicent SIP servlet (my platform is mss-0.8-apache-tomcat-6.0.14-0902061530 ) to create a new B2BUA request when receive an Invite SIP message. As Sip-servlet-1.1 SPEC, Record-Route and Via header fields are not copied from orignal request,  the other headers SHOULD be keep. New B2BUA Invite request remove the Via and Record-Route, however, it also remove the Route header,  which we need this in our project. (see our log)

 
Could you please judge the issue??



Source code:

protected void doInvite(SipServletRequest request) throws ServletException,
            IOException {
        if(logger.isInfoEnabled()) {       
            logger.info("We got INVITE: \n" + request.toString());                           
        }
          String[] forwardingUri=new String[]{"sip:f...@sip-servlets.com", "sip:f...@127.0.0.1:5080"};
            B2buaHelper helper = request.getB2buaHelper();                       
           
            SipFactory sipFactory = (SipFactory) getServletContext().getAttribute( SIP_FACTORY);           
            Map<String, List<String>> headers=new HashMap<String, List<String>>();
            List<String> toHeaderSet = new ArrayList<String>();
            toHeaderSet.add(forwardingUri[0]);
            headers.put("To", toHeaderSet);           
          SipServletRequest forkedRequest = helper.createRequest(request,true,headers);
     
            if(logger.isInfoEnabled()) {
                logger.info("!new forkedRequest = " + forkedRequest);
            }       
            forkedRequest.send();           
    }   


the Log message indicates that  :

Fixed in trunk.
Can you try it from the source ? a new binary snapshot for test should be available soon too.
