Hi,

I am trying to build a simple architecture like this:

UAC <--> Proxy1 <--> Proxy2 <--> UAS

(each on a different VM)

Is it possible to have this architecture built without any "registrar" module?

I have simulated my UAC and UAS using SIPp and the routing in Proxy1 and Proxy2 is to forward to the next hop. for example in Proxy1, I have:

route{
        record_route();
        if (loose_route()) {
                route(FORWARD);
                break;
        }
        if (uri == myself){
                setdsturi("sip:__ADRESS_OF_PROXY2__");
                route(FORWARD);

break;

        }
        route(FORWARD);
}

route[FORWARD]
{
        if (!t_relay()) {
                sl_reply_error();
        }
}

I simulate packets in UAC in the following manner:

sipp -sn uac -rsa __ADDRESS_OF_PROXY1__ __ADDRESS_OF_PROXY1__

The problem is that my first proxy (Proxy1) is always returning "404 Not Found" on any INVITE and never forwards to Proxy2, even though I have asked it to do so in "if(uri==myself)".

Am I missing something in connecting the proxies in such a simple architecture?
