Hi Bodgan
I use loose_route too, any idea?
I have in the openser.cfg:

if (loose_route()) {
                # mark routing logic in request
                append_hf("P-hint: rr-enforced\r\n");
                route(1);
                return;
};

and in the route 1

route[1]
{
        # send it out now; use stateful forwarding as it works reliably
        # even for UDP2TCP
        if (!t_relay()) {
                sl_reply_error();
        };
}

Those are the traces with ngrep, this is the message that the softphone sent to the balancer openser server:

ACK sip:gil@192.168.1.28 SIP/2.0..
Via: SIP/2.0/UDP 192.168.1.28:3806;branch=z9hG4bK8010c001d753db11bc2c000f1f72ea95..

And, this is the message that the balancer openser server send:

Hi Jose,

you need both record_route() and loose_route().
