[Users] WeSIP setup problem

Thu Apr 26 12:55:41 CEST 2007

Hi Gines, thanks for your support

The serlvet code is the following

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

      //Get a proxy for this request
      Proxy callerProxy = callerInvite.getProxy();

	System.out.println("doInvite within neos servlet: requestURI is " +
callerInvite.getRequestURI() );

	callerProxy.proxyTo(callerInvite.getRequestURI());

    }

This code causes the "no route" exception. The println above gives :

doInvite within neos servlet: requestURI is sip:5002 at 192.168.1.11

where 5002 is the called SIP phone and 192.168.1.11 is the address of my OpenSER
+ WeSIP box (i.e. the managed SIP domain)

Following your advice I have tried to change the proxyTo to a different address:

	SipURI dest = sipFactory.createSipURI("5002","192.168.1.16");
      callerProxy.proxyTo(dest);

It that case, the called phone (5002, IP address 192.168.1.16) gets the INVITE
correctly. However, something puzzles me here: the serlvet is not supposed to
know the IP address of the called phone. In my understanding, the AS processes
the INVITE, then it must send it back to the proxy server which is supposed to
forward it to the next hop, is that right ?

Could you please give me an example of a doInvite which basically does nothing
and which lets the INVITE be forwarded to the called party ?

Finally here are my config files:
