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

Hello,

This is not happening when the request is redirected to wesip, using:

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

The request printed in the wesip debug logs have the route.

But if I don't redirect the request to wesip and use the following:

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

}

I see that openser removes the top most Route header.

Am I doing something wrong?

Thanks
