[Users] who removes top most route header? (openser 1.2.0 + wesip) - sr-users

27 Apr 2007

Hi,

I have testing openser 1.2.0 with seas module and wesip.

If I send an INVITE message with a Route header, the SIP servlet receives
the INVITE with the full Route Header, and when I proxy it the Route is the
same, but I expected that the top most Route header has been removed. Who is
in charge to do it? openser or wesip? I first thought it might be openser
through loose_route(), but it seems not to be the case.

The openser cfg file is similar to the example given in wesip tutorial:

route{
       if (!mf_process_maxfwd_header("10")) {
               sl_send_reply("483","Too Many Hops");
               exit;
       };
       if (msg:len >=  2048 ) {
               sl_send_reply("513", "Message too big");
               exit;
       };

    xlog("L_INFO",  "$rm: ci=$ci ft=$ft tt=$tt cseq=$cs ruri:$ru received
from: $si:$sp \n");

        if (!method=="REGISTER")
                record_route();

        if (loose_route()) {
        xlog("L_INFO", "RR enforced\n");
                append_hf("P-hint: rr-enforced\r\n");
                route(1);
        };

        if (uri==myself) {
        xlog("L_INFO", "uri == myself");
                if (method=="REGISTER") {
                        save("location");
                        exit;
                };
                lookup("aliases");
                if (!uri==myself) {
            xlog("L_INFO", "outbound alias\n");
                        append_hf("P-hint: outbound alias\r\n");
                        route(1);
                };
                if (!lookup("location")) {
                        sl_send_reply("404", "Not Found");
                        exit;
                };
        xlog("L_INFO", "usrloc applied\n");
                append_hf("P-hint: usrloc applied\r\n");
        };
        route(1);
}

route[1] {
    if(!as_relay_t("app_server_one")){
        t_reply("500","Application Server error");
    }
}

route[2] {
    xlog ("L_INFO", "$rm: cseq:$cs $ru: RELAYING (PROXY) to $du (flags:
$mF)
...\n");
    if (!t_relay()) {
        sl_reply_error();
    };
    exit;

}

This the log from wesip:
