[reSIProcate] Newbe question about sending sip packets

[Lorenzo <webmaster@xxxxxxxxxxxxx>]

Hi all,
I want to make a simple (maybe the simplest!) program to send a simple
sipmessage using resiprocate stack and a simple udp trasport.
I compile it on linux and windows and it's correct but it doesn't send
any packet!!
Does someone know what's wrong with this code?

Thank you,

Lorenzo

        target.uri().host() = "192.168.0.1";
        target.uri().port() = 5060;

        NameAddr from = target;
        from.uri().user() = "192.168.0.100";
        NameAddr contact = from;
        SipMessage* next = Helper::makeRegister( target, from, contact);
        stack->sendTo(next,outboundProxy);
        delete stack;
        return 0;
