Sip servlets REGISTER does but INVITE doesn't get to my application

[Wojciech Biolik]

Hi I have very wierd problem:

I use sip servlets in my application running on jboss.

I have mobicents-dar-properties file configured like this:

INVITE: ("pl.edu.agh.mobicentsVoIP.servlets.Application", "DAR:To", "TERMINATING", "", "NO_ROUTE", "0"), ("pl.edu.agh.mobicentsVoIP.servlets.Application", "DAR:From", "ORIGINATING", "", "NO_ROUTE", "0")

MESSAGE: ("pl.edu.agh.mobicentsVoIP.servlets.Application", "DAR:From", "ORIGINATING", "", "NO_ROUTE", "0")

OPTIONS: ("pl.edu.agh.mobicentsVoIP.servlets.Application", "DAR:From", "ORIGINATING", "", "NO_ROUTE", "0")

REGISTER: ("pl.edu.agh.mobicentsVoIP.servlets.Application", "DAR:From", "ORIGINATING", "", "NO_ROUTE", "0")

and sip.xml:

<sip-app>

        <app-name>pl.edu.agh.mobicentsVoIP.servlets.Application</app-name>

        <display-name>Mobicents VoIP System</display-name>

        <description>Mobicents VoIP System</description>

        

        <servlet>

                <servlet-name>ProxySipServlet</servlet-name>

                <display-name>ProxySipServlet</display-name>

                <description>Simple Proxy SIPServlet</description>

                <servlet-class>

                        pl.edu.agh.mobicentsVoIP.servlets.ProxySipServlet

                </servlet-class>

                <load-on-startup>1</load-on-startup>

        </servlet>

<listener>

                <listener-class>

                        pl.edu.agh.mobicentsVoIP.servlets.ProxySipServlet

                </listener-class>

        </listener>

</sip-app>

but in my application I recive only REGISTER requests (here are methods impl):

    @Override

    protected void doInvite(SipServletRequest req) throws ServletException,IOException {

            logger.info("Appl don't handle INVITE. Here's the one we got :  " + req.toString());

            super.doInfo(req);

            

    }  

protected void doRegister(SipServletRequest req) throws ServletException, IOException {

        logger.info("Received register request: " + req.getTo());

        int response = SipServletResponse.SC_OK;

        SipServletResponse resp = req.createResponse(response);

        

        Address address = req.getAddressHeader(CONTACT_HEADER);

        User user = facade.getUserByUserURI(req.getFrom().getURI().toString());

        

        if(user == null){

        user = new User(req.getFrom().getDisplayName(), "", req.getFrom().getURI().toString());

        }

        

        int expires = address.getExpires();

        if(expires < 0) {

                expires = req.getExpires();

        }

        if(expires == 0) {

                facade.unRegisterUser(user);

                logger.info("User " + user + " unregistered");

        } else {

                resp.setAddressHeader(CONTACT_HEADER, address);

                facade.registerUser(user);

                logger.info("User " + user + 

                                " registered with an Expire time of " + expires);

        }                               

                                        

        resp.send();

}

my question is why doesn't it work ? 

can anyone give me some clue?
