New subject: Failing in dropping duplicated 200 OK on onreply_route()

16 May 2017

Hi.

I am trying to drop duplicated 200 OK on onreply_route(), but Kamailio
still delivering them:

if (is_method("INVITE") && t_check_status("200") &&
sdp_content()) {
        xlog("L_INFO", "200 OK Received\n");
        if (!isflagset(20)) {
                xlog("L_INFO", "200 OK Relayed\n");
                setflag(20);
        } else {
                xlog("L_INFO", "200 OK Dropped\n");
                drop;
        }
}

...
 From logs, I can see the script is executed, but still
200 OK is relayed: 
INFO: <script>: 200 OK Received
INFO: <script>: 200 OK Dropped
DEBUG: tm [t_reply.c:1234]: t_should_relay_response():
->>>>>>>>>
T_code=200, new_code=200

t_should_relay_response: 200 INV after final sent
DEBUG: tm [t_reply.c:1752]: relay_reply(): DEBUG: relay_reply: branch=0,
save=0, relay=0 icode=0 [...]

How can I proceed to get the desired behavior?
